The Coffee Brew Log

One entry per brew. One change per entry.

When a cup lands where you want it, that entry is your recipe for the rest of the bag.

How to use the log

Dialing in a new bag rarely takes more than two or three brews — if you change one thing at a time and write down what happened. Brew, taste, note what you notice, write the one change the cup asks for (sour → finer · bitter → coarser · weak → +1–2 g coffee), then brew again. When a cup is right, star that entry: it's your recipe for this bag.

Baselines: pour-over 20 g : 320 g · French press 30 g : 480 g · espresso 18 g → 36 g · water 90–96°C (194–205°F) · sour = finer · bitter = coarser · weak = more coffee
