Compare Two Brews
Create a one-variable A/B brew prompt so the next cup teaches you something useful.
A/B brew prompt
Compare two brews without changing everything
Pick one variable, keep the rest boringly identical, then taste Brew A and Brew B side by side. The point is a repeatable next cup, not a perfect tasting note.
Change only this
- Brew A with your usual steep.
- Brew B 10-20 seconds shorter or longer.
Write after tasting
- First aroma
- Body
- Change between steeps
- Finish
- Which cup would you repeat?
Decision rule
Pick A, pick B, or split the difference. Do not change a second variable until the next comparison.
Most bad tea experiments change too many things at once. This prompt keeps the comparison narrow: one variable changes, the rest stays stable, and the result becomes a decision you can repeat.
When to use it
- Your green tea is sometimes bitter, but you are not sure whether time or temperature moved.
- Your oolong tastes better in one vessel, but you want to test it without guessing.
- You bought a new water or changed your filter and need one clean comparison.
- You want a journal note that leads to the next brew, not just a tasting adjective.
Use it with the guides
Start with the brewing timer, then save the winning setup in the tea journal. If you are comparing styles, read gongfu vs western brewing first.
