The resting experiment got weird

[Typecase1984]

Brewer and filter: Hario V60 02 ceramic; Cafec Abaca 02
Grinder, burr and calibration: KINGrinder K6; 48 mm conical burr; 92 clicks from zero
Bean, roaster, process and roast date: Peru Cajamarca decaf; local specialty roaster; EA decaf; roast date 2026-07-04
Dose and water mass: 20.0 g coffee; 320 g water
Temperature and water profile: 94°C; filtered tap water, about 85 ppm TDS
Pour/agitation schedule: 60 g bloom for 45 s, then two even pours to 320 g; one gentle swirl
Drawdown time: 3:05
Expected and perceived flavour: expected clean citrus and tea-like finish; perceived cup is bitter in the finish
Changes already tested: changed grind one step coarser; kept everything else fixed

I have enough contradictory impressions in my notes that I finally stopped guessing and ran the same coffee side by side. This is not laboratory science, but at least the variables are written down.

Every hobby eventually becomes labelled freezer bags, apparently.

This is exactly the kind of note I want in a forum: date, setup, what changed, and what happened. Future searchers can do something with it.

came for a recipe, left with municipal water policy

i’d keep the current recipe for another two brews before changing anything. One good cup can be luck; three similar cups is information.

I am less convinced by the flavour claim than the workflow claim, but that may be because my water is different.
