Wendougee DATA S or LITA BA: Which Profiling Espresso Machine To Buy?

The short version (read this first)

Wendougee DATA S or LITA BA? One of the questions we get asked most often is whether to choose the DATA or the LITA, The Wendougee DATA S and the Wendougee LITA BA share the same DNA: dual boilers, a saturated 316L stainless group, German WIKA pressure sensing, an Italian GICAR flow meter, and the E-Bar profiling app. They differ in pump, steam power, footprint, and price. The DATA S is the no-compromise flagship; the LITA BA is the compact, more affordable way into the same profiling world.

Here is our honest take, and we sell both so weigh it accordingly. The DATA S is for the enthusiast barista who wants everything. Its gear pump protects the puck and tracks profiling curves more smoothly, its big 1.8-litre steam boiler handles milky drinks and small home gatherings, its larger saturated brew boiler holds temperature through long sessions, and it plumbs straight into a water line so you never refill a tank. The LITA BA is for lighter home use, roughly five to ten cups a day, in a small kitchen. It keeps the premium components and most of the profiling experience in a smaller, phone-free package, which makes it a great first serious machine for someone who doesn't want to compromise on quality.

If you want the reasoning, the specs, and which one fits your kitchen, keep reading. Everything below backs up that recommendation.

What's the right option if I'm just starting my coffee hobby?

If you are entering the coffee world and want your first serious machine, the LITA BA is usually the smarter starting point, and the DATA S is the one to choose if you already know you want the flagship and plan to entertain or steam a lot of milk. Both let you start simple and grow, which is exactly what a newcomer needs.

Here's the part worth saying plainly. At this level, your grinder, your beans, and your technique shape the cup more than the choice between these two machines. A profiling machine rewards you most once your fundamentals are solid, so a beginner's early wins come from dialing grind and ratio, not from chasing complex curves. Both machines save profiles you can run with one touch while you learn, then open up the full E-Bar app when you're ready. If you want the science of why profiling helps, our guide to pressure and flow profiling breaks it down.

So a beginner is not "settling" with the LITA BA. You get the same saturated group, the same commercial sensors, and the same app as the flagship, in a machine that costs less and fits a normal kitchen.

Wendougee DATA S or LITA BA: what's actually different?

The DATA S and LITA BA differ in four ways that decide the rest: pump technology, steam capacity, footprint, and price. They are built on an identical philosophy, so this is a question of degree, not of quality tiers.

Start with what they share, because it's most of the machine. Both are semi-automatic dual boilers with a saturated 316L stainless group head machined as one block with the brew boiler, the same approach commercial La Marzocco machines use. Both carry a German WIKA pressure sensor and an Italian GICAR flow meter, the kind of commercial-grade parts that feed live data to the E-Bar app so the pump self-corrects mid-shot. Both profile pressure or flow, save recipes per bean, stop the shot by weight with a BooKoo scales, and sync grind size with Wendougee Wendougee MILO and ARES grinders.

Now the forks. The DATA S uses a gear pump; the LITA BA uses two electromagnetic vibratory pumps. The DATA S carries a 1.8-litre steam boiler and a 0.8-litre brew boiler; the LITA BA carries 0.8 litres and 0.35 litres. The DATA S is full stainless and bigger; the LITA BA is coated steel, much shallower, and adds an onboard screen so you can run it without your phone. And the DATA S costs €3,695-3,795 against the LITA BA's €2,299-3,380.

Gear pump vs dual vibratory pumps: the real difference

A gear pump moves water by meshing gears at variable speed, giving smooth, quiet, precise pressure that holds a target as the puck changes. The LITA BA's two vibratory pumps run at offset frequencies to emulate that smoothness, distorting the puck far less than the single vibratory pump in most machines, though not quite matching gear-pump smoothness.

The LITA BA's two vibratory pumps

This is the single most important hardware difference. The DATA S adjusts pump speed hundreds of times per second to track whatever curve you've programmed, which matters most on the gentle declining tails that delicate light roasts reward. Owners describe it as quiet enough that an early shot won't wake someone in the next room, and reviewers rate the gear pump as better than rotary for control.

The DATA S Gear Pump

The LITA BA's dual-pump design is a genuinely clever middle path. Two pumps under software control correct each other to hold a target pressure, and because they vibrate at different frequencies they cause much less puck disturbance than a typical one-pump machine. They sit between a classic vibratory machine and the DATA S on noise, and for everyday espresso and most profiling they are more than capable. The gear pump simply tracks a complex curve more exactly.

Which one makes better espresso?

For most people, both machines make excellent, café-quality espresso, and the gap in the cup is small. The DATA S has the edge when you chase the most faithful, repeatable reproduction of a complex multi-stage curve, especially on light roasts. The LITA BA delivers the great majority of that same experience.

The honest answer is that your grinder and beans decide more than the pump does. Give both the same well-dialed puck and the cups land close together. Where the DATA S pulls ahead is precision under demand: the gear pump plus the larger brew boiler holds a steadier line through long, back-to-back dial-in sessions. Where the LITA BA shines is that it brings the same saturated group and the same profiling app to a far smaller, cheaper machine, so the espresso quality is closer than the price gap suggests.

Which has better steam for milk drinks?

The DATA S is clearly the better steamer. Its 1.8-litre steam boiler climbs to around 2.5 bar at around 140°C, textures a 500 ml jug (two flat whites) in one pull, and recovers fast for back-to-back drinks, which is the right tool if you entertain or make several milk drinks in a row.

Wendougee DATA S 1,8L Steam boiler

The LITA BA's 0.8-litre steam boiler is no slouch. It reaches up to 2.5 bar at 140°C and textures a 500 ml jug for two flat whites comfortably. The real difference is recovery and sustained volume. The LITA BA is happy making one or two drinks at a time; the DATA S is the one to pick for larger jugs, several drinks in a row, or a small gathering at home.

Which is better for light roasts?

The DATA S has a small but real edge for serious light-roast work. Light roasts are dense and reward a gentle pre-infusion and a smooth declining pressure tail, which the gear pump tracks most precisely, and the larger 0.8-litre brew boiler holds temperature through the three or four shots a tough dial-in can take.

Wendougee DATA S 0,8L saturated group head

That said, the LITA BA handles light roasts well too. Its has 0.53l saturated group head and incoming-water pre-heating keep brew temperature steady, and its dual pumps still profile pressure or flow in 0.1-bar steps across the full range. If light-roast dial-in is your main pursuit and you tune across many shots in a session, the DATA S gives you more thermal headroom. For most light-roast drinking, the LITA BA is more than enough.

Which has better build quality and longevity?

Both are built to a commercial standard with serviceable, mostly-metal internals, and the DATA S sits a step higher on materials. It has a full stainless-steel body; the LITA BA uses a coated cast-steel body. Both use 316L stainless boilers, a saturated 316L group, copper pipework, and side panels that come off easily for service.

Which is better for small kitchens?

The LITA BA is the clear winner for tight spaces. At 261 mm wide and just 386 mm deep, it is materially smaller than the DATA S, which is 290 mm wide and 490 mm deep (closer to 50 to 52 cm once you account for hoses). On a standard 60 cm worktop, the LITA BA's shallow depth is a real practicality win, especially with a backsplash or shelf behind it.

The LITA BA is also lighter at 22 kg versus 25 kg, and draws less power (2100 W versus 2800 W) because it heats smaller boilers. Both can be plumbed in with an included kit, and both hold a similar tank volume (1.2 litres for the LITA BA, 1.5 litres for the DATA S). If counter depth is your constraint, the LITA BA is built for it.

Is the DATA S worth the extra money?

For the enthusiast who wants the flagship, yes. The premium price buys the gear pump, the much larger 1.8-litre steam boiler, the bigger brew boiler, a full stainless body, three finishes, and direct plumb-in in the box. If you steam a lot of milk, entertain, pursue light-roast precision seriously, or simply want the end-game machine, that money is well spent.

For lighter use, it's harder to justify, and that's the point of the LITA BA. the LITA BA returns the onboard screen and Intelligent Disc, a smaller footprint, and the same premium internals. You give up steam capacity, some thermal reserve, gear-pump smoothness, and the full stainless body, but you keep the core profiling experience. So the DATA S is worth it for the enthusiast who wants everything; the LITA BA is the smarter spend for almost everyone else.

Which is better value?

Value depends on how you'll use the machine. For lighter home use and small kitchens, the LITA BA is the stronger value: you get café-level profiling and commercial-grade parts. For heavy use, milk-forward routines, and end-game ownership, the DATA S earns its premium on steam, thermal mass, and the gear pump.

There's no single right answer, which is why we keep splitting it by buyer. A newcomer or a one-to-two-drink household gets more value from the LITA BA. An enthusiast who entertains and chases profiling precision gets more value from the DATA S over the life of the machine. Same philosophy, two honest answers.

How do they compare to the Decent and La Marzocco?

Both Wendougees play in Decent DE1/DE1XL profiling territory, but as true dual boilers they brew and steam at once and offer real steam power, which the thermoblock Decent can't match without add-ons. The trade is that the Decent profiles temperature mid-shot (neither Wendougee does) and has a much larger profile-sharing community. On price, the €3,695-3,795 DATA S undercuts the DE1XL.

Against La Marzocco, the contrast is different. The Linea Mini retails far higher (roughly 2.5 times the LITA BA) and brings brand prestige and a saturated group, but no programmable profiles, no flow profiling, and no built-in gravimetric dosing. The LITA BA matches the Micra on saturated group and dual-boiler architecture and adds the programmable profiling the Micra lacks; the Micra wins on rotary-pump feel and prestige. If you want hands-on analog control instead, a Lelit Bianca V3 gives you a manual flow paddle, and an ECM Synchronika gives you a traditional E61 dual boiler that never changes, neither offers repeatable saved profiles.

Which should you buy, and what Vellutto recommends

Vellutto recommends the DATA S for enthusiast baristas who steam milk, entertain or run small events at home, and care about puck integrity and the smoothest profiling curves; it's an extremely capable machine with commercial-level steam, excellent thermal stability from the bigger saturated brew boiler, and direct water plumbing for easy daily life. We recommend the LITA BA for lighter home use of around five to ten cups a day: a small footprint, great build quality, premium components, and a great choice for people starting their coffee hobby who don't want any compromises.

We sell both, so this isn't a neutral ranking, but it is an honest one. Put simply: the DATA S is for the enthusiast who wants everything; the LITA BA is for the enthusiast who wants almost everything, smaller and cheaper. If you tell us how you drink your coffee, how much milk you steam, and how much counter space you have, we'll point you to the right one. You can buy the Wendougee DATA S here or the Wendougee LITA BA here. Both ship insured across the EU and EEA with a two-year warranty.

Full specifications, side by side

Note on the LITA variant ladder: BR = 1 pump, pressure control, no hot-water tap (entry); LR = 1 pump + hot-water tap; BA = 2 pumps + flow-priority mode (the version Vellutto stocks); LA = 2 pumps + flow-priority + a hot-water tap from the group head. The LITA LA is identical to the BA apart from that tap. Both machines profile pressure or flow per profile (not both at once), and neither profiles temperature mid-shot.

Overview & Key Differences

What is the difference between the Wendougee DATA S and the LITA BA?

Both the Wendougee DATA S and the Wendougee LITA BA are app-controlled dual-boiler espresso machines that share the same 316L stainless-steel saturated group head and full pressure- and flow-profiling capability. The difference is scale and intent. The DATA S is the flagship: a 1.8 L steam boiler and 0.8 L brew boiler, a quiet commercial-grade gear pump, a full stainless-steel body and a wooden profiling paddle. The LITA BA is the compact, more affordable model: a 0.8 L steam boiler and 0.35 L brew boiler, twin electromagnetic vibratory pumps, and a built-in Intelligent Disc controller so you can run saved profiles directly from the machine. In short, the DATA S offers more steam power and capacity, while the LITA BA delivers the same profiling experience in a smaller, lower-cost package.

Wendougee DATA S or LITA BA — which one should I buy?

Choose the DATA S if you want maximum steam power for milk-based drinks, the smoothness of a gear pump, a larger water tank and the option to plumb directly into a water line. Choose the LITA BA if counter space and budget matter most, or if you like having on-machine controls so you don't need your phone for every shot. Both pull the same quality of espresso thanks to the shared saturated group head and PID-controlled dual boilers — so the decision usually comes down to steam capacity, footprint and price rather than cup quality.

Is the LITA BA simply a cheaper version of the DATA S?

In many ways, yes. The LITA BA keeps the core of what makes the DATA S special — the 316L saturated group head, true dual boilers, E-Bar pressure and flow profiling, and Bluetooth grinder and scale integration. To reach a lower price and smaller size, it uses smaller boilers and twin vibratory pumps instead of the single gear pump, in a more compact body. For many home baristas, the LITA BA captures most of the DATA S experience for noticeably less.

Specifications & Hardware

What are the boiler sizes on each Wendougee machine?

The DATA S has a 1.8 L steam boiler and a 0.8 L brew boiler. The LITA BA has a 0.8 L steam boiler and a 0.35 L brew boiler. Both are stainless steel and feed a saturated group head, but the larger boilers on the DATA S give it more steam reserve and thermal stability when you're making several drinks in a row.

What type of pump does each machine use?

The DATA S uses a single commercial-grade gear pump, which runs quietly and delivers exceptionally smooth, repeatable pressure transitions — ideal for flow profiling. The LITA BA uses two electromagnetic vibratory pumps working together, which still allow precise pressure and flow control but are slightly louder than the gear pump. Both give you full profiling; the gear pump is simply the more refined, quieter solution.

What group head do the DATA S and LITA BA use?

Both machines use a saturated group head machined from 316L stainless steel — the same premium grade used in commercial-level boilers. Because the group is integrated into the brew boiler, temperature stays extremely stable and there is no cooling flush needed before your first shot, unlike traditional E61 machines.

How big are the DATA S and LITA BA, and how much do they weigh?

The DATA S measures 290 × 490 × 370 mm and weighs about 25 kg. The LITA BA measures 261 × 386 × 334 mm and weighs about 22 kg. The LITA BA is smaller in every dimension, which makes it the easier fit for compact kitchens and tighter coffee bars.

What portafilter size do they use?

Both machines use a standard 58 mm bottomless portafilter with a wooden handle, included in the box. This means they're compatible with the wide range of 58 mm baskets, tampers and accessories already on the market.

What commercial-grade components are inside?

Both machines are built around professional instrumentation: a German WIKA pressure sensor and an Italian GICAR sensors flow meter, which together enable accurate pressure and flow profiling. The DATA S additionally features a WIKA analog steam-pressure gauge on the front panel. These are the kinds of components you'd expect to find in commercial equipment, which is a large part of why both machines profile so precisely.

Performance & Taste

Which machine has more steam power?

The DATA S has the stronger steam, thanks to its larger 1.8 L steam boiler — it can texture a full milk jug quickly and is well suited to back-to-back cappuccinos and flat whites. The LITA BA's 0.8 L steam boiler is impressive for such a compact machine and is more than enough for one or two milk drinks at a time, but it has less reserve when you're steaming continuously.

Do these machines make café-quality espresso?

Yes. Both deliver excellent, consistent espresso thanks to the saturated group head, PID-controlled dual boilers and precise profiling. Owners frequently report sweeter, fuller-bodied and more nuanced shots than they achieved on machines costing significantly more. As always, your results also depend on a good grinder, fresh beans and proper dial-in — the machine gives you the control, and the rest is technique.

Can both machines do pressure and flow profiling?

Yes — both the DATA S and the LITA BA support full pressure profiling and flow profiling, programmed through the free E-Bar app and then saved to the machine. Each step of a profile is set to prioritise either pressure or flow, giving you fine control over pre-infusion, ramp-up and decline across the shot. The flow-priority capability is exactly what the "BA" designation refers to in the LITA range.

Can either machine change brew temperature during a shot?

No. Neither the DATA S nor the LITA BA offers in-shot temperature profiling. Instead, both hold a precise, stable brew temperature set by their dual PID boilers. You get full control over pressure and flow throughout the shot, with rock-solid temperature consistency from start to finish.

How long do they take to heat up?

Both machines reach brew-ready temperature in roughly ten minutes from cold — faster than most traditional E61 dual boilers. For the most consistent first shot, we recommend letting the machine settle for a couple of extra minutes after it signals ready.

Use Case & Who Each Machine Is For

Which machine is better for a small kitchen?

The LITA BA. At 261 mm wide and 22 kg, it's purpose-built for limited counter space, while the DATA S is wider, deeper and heavier. If your worktop is at a premium, the LITA BA is the more practical choice without giving up the dual-boiler profiling experience.

Is the DATA S a good machine for home use?

Absolutely. The DATA S is a prosumer machine designed for advanced home baristas who want an end-game setup. It has enough steam power and capacity to handle a busy household or even a small coffee cart, while still being at home on a kitchen counter. If you want the most capable machine in Wendougee's line-up and have the space for it, the DATA S is built for you.

Is the LITA BA suitable for beginners?

It can be a great entry into serious espresso. You don't need barista training to get started — saved profiles run from the on-machine Intelligent Disc with a single press, and the physical controls behave exactly as you'd expect. The deeper profiling features are there whenever you're ready to grow into them, so the LITA BA can be both an approachable first machine and one you won't outgrow quickly.

Which machine is best if I make a lot of milk drinks?

The DATA S, because its larger steam boiler textures milk faster and recovers more quickly between drinks. If lattes, cappuccinos and flat whites are your daily routine — especially for more than one person — the extra steam capacity of the DATA S makes a real difference.

Can these machines be used commercially?

The DATA S in particular has the steam power and plumbing capability for light commercial or coffee-cart use. Please note that warranty terms differ for business use, so if you plan to run either machine commercially, check the warranty details on the product page or get in touch with our team first.

Smart Features, App & Ecosystem

Do I need a tablet or phone to use these machines?

No. After a one-time setup using the free E-Bar app on any iOS or Android device, both machines run on their own — the DATA S from its paddle and saved profiles, and the LITA BA from its built-in screen and Intelligent Disc. A dedicated tablet is an optional accessory and is not required for everyday use.

Which grinders and scales connect over Bluetooth?

Both machines pair with Wendougee's MILO grinders, so your grind setting can sync to each saved profile, and with compatible BooKoo smart scales for shots that stop automatically by weight. The DATA S also pairs with the larger ARES grinder. Any third-party grinder will of course still work alongside either machine as a standard, non-connected grinder.

Can I share and download espresso profiles?

Yes. The E-Bar app includes a community section where you can upload your own recipes and download profiles created by others. A downloaded profile is a great starting point — you'll still fine-tune grind size and parameters to suit your specific beans and water for the best result in the cup.

Can the firmware be updated?

Yes. Both machines receive firmware updates wirelessly through the E-Bar app over Bluetooth — there's no need for cables or a service visit. New features and refinements are delivered over the air, so your machine keeps improving over time.

Setup, Plumbing & Maintenance

Can these machines be plumbed into a water line?

The DATA S can run from its internal water tank or be connected directly to a water line, with a plumb-in kit supplied in the box. The LITA BA is designed primarily to run from its internal reservoir, which keeps installation simple and flexible for any kitchen. If direct plumbing is essential for your setup, the DATA S is the model built for it.

How large are the water tanks?

The DATA S has a 1.5 L removable water tank, while the LITA BA has a 1.2 L removable tank with a clear level indicator. Both are easy to lift out and refill, and the DATA S can also be plumbed in if you'd prefer not to refill a tank at all.

What kind of water should I use?

Always use filtered water in the recommended hardness range — roughly 35–85 ppm. Water that is too soft lacks the minerals needed for proper extraction and for the machine's sensors to work correctly, while water that is too hard causes scale build-up, one of the most common causes of damage to any espresso machine. We don't recommend using plain distilled or reverse-osmosis water unless it has been remineralised.

How do I maintain these machines?

Maintenance is straightforward. Each day, flush the group head and wipe down the steam wand. Each week, backflush with a blind basket and an espresso machine detergent. Every three to six months, descale based on your water hardness. The E-Bar app helps by tracking your maintenance intervals so nothing gets overlooked.

How noisy are they in use?

The DATA S is notably quiet — its gear pump produces a smooth, low hum, and most owners find the grinder and steam louder than the pump itself. The LITA BA's twin vibratory pumps are quieter than a conventional single vibration pump, though not quite as silent as the DATA S gear pump. Both are comfortable to use in a home kitchen.

Availability, Warranty & Buying

What warranty do these machines come with?

Both the DATA S and the LITA BA are covered by our warranty, with after-sales support and spare parts available within the EU and EEA. Buying through Vellutto means your machine is backed locally, so you're not relying on overseas support if you ever need help. Full warranty terms are listed on each product page.

Are the DATA S and LITA BA in stock?

Availability can vary as these machines are in high demand. At times they ship straight from stock, and at others popular models may be offered on pre-order. The quickest way to check current availability and lead times is to view the live product page for the model you want, or contact our team and we'll let you know.

Should I be concerned about after-sales support for a Wendougee machine?

This is a fair and common question. Wendougee machines are widely praised for their build quality and capability, and buying through Vellutto removes the main concern by giving you EU-based warranty coverage, spare parts and support. You get the performance of a forward-thinking brand with the reassurance of a local point of contact.

What's included in the box?

Both machines include a 58 mm bottomless wooden portafilter, filter baskets, a backflush disc, a tamper and a stand for your phone or tablet. The DATA S additionally includes a plumb-in kit. For the exact, up-to-date contents of the model you're considering, please refer to its product page.

What do the LITA model names (BR, LR, BA, LA) mean?

The LITA range uses these codes to indicate features. BR is the entry model with a single pump and pressure control. LR adds a hot-water tap. BA — the version we stock — uses dual pumps and adds flow-priority profiling. LA combines dual pumps and flow profiling with a hot-water tap. So the "BA" in LITA BA tells you it's the dual-pump, flow-profiling model.

Gear pump vs dual vibratory pumps: what's the real difference?

A gear pump meshes gears at variable speed for smooth, quiet, precise pressure that holds a target as the puck changes. The LITA BA's two vibratory pumps run at offset frequencies to emulate that smoothness and disturb the puck far less than a single pump, but they don't fully match the gear pump's smoothness or quietness.

Which makes better espresso, the DATA S or the LITA BA?

Both make excellent café-quality espresso, and the difference is small. The DATA S tracks complex profiling curves more precisely, which helps most on light roasts and long sessions. The LITA BA delivers the great majority of that experience with the same saturated group and app. Your grinder and beans matter more than the pump.

Is the Wendougee DATA S worth the extra money?

For enthusiasts who steam a lot of milk, entertain, or chase light-roast precision, yes. premium buys the gear pump, a much bigger steam boiler, more thermal mass, a full stainless body, and plumb-in. For lighter home use, the LITA BA gives most of the experience for a cheaper price.

Which has better build quality and longevity?

The DATA S sits a step higher on materials with its full stainless body versus the LITA BA's coated cast steel, though both use 316L boilers, a saturated group, and copper pipework. Wendougee is a newer brand whose Western parts network is still growing, but EU importers stock parts and offer a two-year warranty.

Which should a beginner buy?

A beginner who wants their first serious machine usually gets more from the LITA BA: the same premium components and profiling app in a smaller, cheaper, phone-free package. A beginner who already knows they'll entertain and steam lots of milk should choose the DATA S. Both let you start on a saved profile while you learn.

How do the Wendougees compare to the Decent DE1?

Both play in Decent profiling territory, but as true dual boilers they brew and steam at once with real steam power, which the thermoblock Decent can't match without add-ons. The Decent profiles temperature mid-shot and has a larger profile-sharing community. The €3,695-3795 DATA S undercuts the DE1XL on price.
