Changes to Recipe. Stayed true to the recipe, this time, instead of this lunch failed experiments with the ratio, I kept the ratio the same 1:2, with an aim of 32 g out, got around 33.5 g, and tried to keep the thing short from a Brew Time perspective. Following “the rule”, I aimed of having from pre-infusion to cup a 25-30 second brew time.

Notes. I overshot the brew time, however, being a lever machine I think it’s fine. What I should probably do, to keep things simple, is aiming to having 15 seconds of pre-infusion where I stop pumping when I see first drops accumulating on the basket. Then, start pumping to keep pressure high and stable till I reach the 32 g out.

This time, I had a 32-35 seconds brew time, 33.5 g out and was one of the best coffee ever had. No harshness, no unpleasant acidity, good chocolaty and nutty flavor. Perfect crema and thick body.

I will add to the Espresso with The Steam & Co., 1ZPresso Jx-Pro on Wacaco Picopresso recipe a note on brew time and changing the pre-infusion method.

From this old recipe:

Old Recipe

Procedure.

  1. Heat water in kettle;
  2. Grind The Steam & Co. Coffee with 1ZPresso JX-Pro with 1.6.1 clicks settings;
  3. Prepare coffee puck by using needle, screen and tamper;
  4. Pre-heat both Coffee Glass and the Wacaco Picopresso;
  5. Pump water through until you feel a bit of resistence from the puck (around ten pumps) and wait 10 seconds;
  6. After the pre-infusion, pump until you reach 32 g of coffee out (I usually aim towards 32 g but get a little more, more like 33 - 34 g out, which I think is preferable).

To the new recipe:

New Recipe (Changes at 5. and 6.)

Procedure.

  1. Heat water in kettle;
  2. Grind The Steam & Co. Coffee with 1ZPresso JX-Pro with 1.6.1 clicks settings;
  3. Prepare coffee puck by using needle, screen and tamper;
  4. Pre-heat both Coffee Glass and the Wacaco Picopresso;
  5. Start Timer. Pump water through until you feel a bit of resistence from the puck (around ten-twelve pumps);
  6. At the 15 second mark, start pumping again until you reach 32 g of coffee out (I usually aim towards 32 g but get a little more, more like 33 - 34 g out, which I think is preferable). Stop Timer.
    You should aim to have a final timer for the brew of around 30 seconds.
