About this category

The second fermentation happens in the bottle, which means the bottle is under pressure. Correct bottles, correct fill height and a measured amount of sugar are what keep carbonation pleasant instead of dangerous.

Every tool page states the fermentation stages it applies to, the batch size it suits and the safety notes that matter for it. Batch sizes are given as ranges because the right size depends on how much you drink and how often you want to brew.
