Question 1

What’s the difference between the Wendougee Lita BA and the Data S?

Accepted Answer

For me the big differences are the internals and the intended use. The Data S is built more like a commercial tank (more robust, stronger steam, meant to push coffee after coffee), and it uses a gear pump. The Lita BA is more compact and uses dual vibratory pumps, so you’ll hear that familiar vibratory pump sound, but for home volumes it’s honestly more than enough.

Question 2

Can you share the pressure profile you used in this video?

Accepted Answer

Yes—my idea was a free-flow style profile: I start with a low-pressure pre-infusion around 2 bar for about 5 seconds, then ramp up to roughly 8 bar, and slowly reduce the pressure as the shot runs. I used it as a baseline to try and replicate between the Lita and the Data S. In the end, I also pulled the Data S manually to get the yield and taste I wanted.

Question 3

What grinder settings did you use on the Wendougee Milo grinder?

Accepted Answer

In this session I ran the Milo at 500 RPM and 150 micron, and I used the DF54 catch cup. It was a bit too coarse for that coffee, and the first shot on the Lita sprayed and channeled. That said, it’s a good starting point if you want to see how responsive the profile changes feel on these machines.

Question 4

Why did the “ugly” shot taste better than the nicer-looking one?

Accepted Answer

This happens more often than people like to admit—taste is king. My first shot on the Lita looked messy and fast, but it tasted sweet and nutty, and I could still enjoy the blend even with 40% robusta. The Data S shot looked cleaner at first, but the taste was more acidic and astringent until I adjusted and went manual.

Question 5

How does steaming milk compare between the Lita and Data S?

Accepted Answer

The Data S steam is extremely powerful—at my setting around 125–126°C it’s fast and gives very velvety milk. The Lita is still very strong for a compact dual boiler and the steam is consistent and pleasant to use. The main difference is the feel and refinement, plus the Lita’s steam activation is a simple button on the group which is functional but not as convenient as a classic lever/switch.

Question 6

What water do you use for espresso on the Data S?

Accepted Answer

I use a two-stage filter system under my sink that mainly filters out calcium. I know some calcium is needed, but I don’t want to risk scale in the machines. This setup lets me worry less about maintenance and scaling issues long term.

Question 7

How do you roast on the Kaleido M10 Sniper in this video?

Accepted Answer

I run it with Artisan and use auto-roast by following a saved roast profile. The machine does the control work, and the main manual step is dropping the beans. For small orders it’s super practical, and I still keep a larger 5kg production roaster for bigger batches.
