Bengle's first espresso
My team got the main parts of Bengle working last night, and this morning I got to make my first espressos on it. This is the first publicly seen espresso made with our next-generation espresso machine.
A few notes:
- I'm using a blue handle, just because it's what I had at hand. The correct portafilter handle will be white, like the other handle you can see on Bengle.
- this profile has a programmed preinfusion rate of 8ml/s, but on another profile, that asks for “max flow rate” I get a peak of 13 ml/s. Our DE1 maxes out in the 7 ml/s range, so this is a big improvement.
- this profile has an intentional pause right after preinfusion, which is why everything goes quiet. This lets the coffee “bloom” and is especially beneficial for light to medium light roasted beans.
- there are lots of little bugs! You might notice the oscillation on pressure, the chart data has some empty spots.
- the built in scale hardware is working, but I haven't yet had the time to program the app to use it, so I used our Half Decent Scale instead here.
- however, Bengle now works well enough to make really tasty drinks.
- and so we're finally getting close to being able to ship these out to customers.
