The bed looks muddy every single time

[Barroom Radio Nights]

Brewer and filter: AeroPress Original; AeroPress paper
Grinder, burr and calibration: Fellow Ode Gen 2; Gen 2 flat burrs; 5.1; chirp point checked
Bean, roaster, process and roast date: Colombia Pink Bourbon; Kawa; anaerobic washed; roast date 2026-08-28
Dose and water mass: 15.0 g coffee; 255 g water
Temperature and water profile: 91°C; bottled low-mineral water, about 45 ppm TDS
Pour/agitation schedule: single continuous main pour after a 45 s bloom; one small excavation with spoon only if dry pockets remain
Drawdown time: 3:05
Expected and perceived flavour: expected cocoa and red fruit; perceived cup is thin despite adequate extraction time
Changes already tested: changed filter paper and repeated the same recipe

I am trying not to solve this by buying another object. The symptom has repeated three times, and the current log is below. I would rather change one variable, brew again, and report back.

I tested one change from the opening post and it moved the cup, but did not finish the job. Next variable: lower water temperature by 2°C. Why: paper speed is an easy hidden variable to rule out before blaming the grinder. Expected result: slightly more body without making the cup muddier. I will report the actual result rather than stack another change on top
