### Stir at 8 Hours and Extraction Yield
host: [Cordwell Roastworks](../organizations/cordwell-roastworks.md) · updated 2026-03-14 · id: op-stir-at-8-hours-and-extraction-yield
- 2026-03-12: raised — does a gentle stir at t=8 h lift extraction yield without pulling silt into the cup? testing planned for the following week.
- 2026-03-14: resolved — a single gentle stir at t=8 h raised concentrate TDS slightly (4.3% vs. 4.0% for an unstirred control) with no added astringency; adopted for batch-scale brews only.

### Concentrate TDS vs. Steep Hours Curve
host: [Cordwell Roastworks](../organizations/cordwell-roastworks.md) · updated 2026-03-17 · id: op-concentrate-tds-vs-steep-hours-curve
- 2026-03-12: raised — map concentrate TDS against steep time at 10, 12, 14, 16, and 18 hours into a single curve.
- 2026-03-17: resolved — a room-temperature, 1:8 concentrate measured 3.1% TDS at 10 h, 3.5% at 12 h, 4.0% at 14 h, 4.1% at 16 h, and 4.2% at 18 h, plateauing past about 16 hours.
