Know Why Your Batch Went Wrong.

BrewLab diagnoses your homebrew problems and tells you exactly what to fix next time. Beer, mead, cider, wine — anything you ferment at home.

The Problem

You post on Reddit. You get six different answers, half of them wrong. You dig through forums for an hour. You shrug and try again next month.

You deserve to know why.

Diagnosis — 2 probable causes
72%
Fermentation pulled too early
Diacetyl and sulfur together strongly suggest yeast was removed before completing cleanup. Add a 48hr diacetyl rest at 68°F before cold crashing next batch.
21%
Fermentation temp dropped mid-process
A temp drop below ~62°F during active fermentation can cause yeast to go dormant before finishing. Monitor with a probe thermometer and insulate your fermenter.
