The Switch is making me lazy and I think I like it

[Sentence-Teacher]

Brewer and filter: Hario Switch 03; Hario 03 paper
Grinder, burr and calibration: 1Zpresso K-Ultra; 48 mm conical burr; 7.1 from zero
Bean, roaster, process and roast date: Ethiopia Bombe; SEY Coffee; natural; roast date 2026-07-04
Dose and water mass: 20.0 g coffee; 320 g water
Temperature and water profile: 96°C; Lotus-style remineralized distilled water, moderate hardness / low alkalinity
Pour/agitation schedule: 70 g bloom for 40 s, then three pours; no stirring after bloom
Drawdown time: 4:10
Expected and perceived flavour: expected floral sweetness and clear acidity; perceived cup is flatter and drier than expected
Changes already tested: changed grind one step coarser; kept everything else fixed

The annoying part is that the cup is not terrible, just clearly wrong in a repeatable way. I want one next experiment rather than a shopping list of fixes. If you have run Hario Switch 03 with something similar, I am especially interested.

I tested one change from the opening post and it moved the cup, but did not finish the job. Next variable: reduce the final pour by 20 g. Why: this coffee may still be releasing enough gas to disturb the early extraction. Expected result: more even early flow and a sweeter cup as it cools. I will report the actual result rather than stack another change on top.

i’ve used Ethiopia Bombe on the same Hario Switch 03 / 1Zpresso K-Ultra combination. Change: reduce the final pour by 20 g. Why: the last part of the brew may be adding dryness without useful sweetness. Expected result: a 15–30 second faster drawdown and a cleaner finish. Keep everything else exactly where it is for one brew.

Same Hario Switch 03 and grinder here, different but similarly light coffee. Change: change only the filter paper. Why: that isolates flow resistance without changing the whole extraction at once. Expected result: a flatter bed and less drying finish. That should tell you whether the behaviour belongs to the setup rather than this exact bag

Controlled-test suggestion: reduce the final pour by 20 g. Why: the last part of the brew may be adding dryness without useful sweetness. Expected result: more even early flow and a sweeter cup as it cools. Do two brews if you have enough coffee, one current recipe and one changed variable, and taste them side by side as they cool.
