Upgrade your second ferment.
Standard flip-top bottles hold pressure with nowhere for it to go. KOMBU bottles use a custom pressure-relief cap that vents automatically when carbonation builds too high, which helps prevent bottle bombs and keeps your fizz consistent from batch to batch.
The wide mouth makes it easy to add fruit, pour, and clean, and the bottles are built to last.

Glass Bottle
Secondary fermentation in the bottle creates natural carbonation (that delightful fizz!) when sugar or juice is added. Our wide-mouth glass bottles are built to withstand high pressure and make adding fruit, pouring, and cleaning effortless.
Carbonation Cap
Our bottle caps feature a Pressure Relief Valve (PRV) built right into the caps. This feature provides an extra layer of safety by releasing pressure automatically if it reaches 65 psi.
PRV
We integrated the PRV into the cap to preserve the bottle’s clean aesthetic while adding essential functionality. The cap remains fully removable for easy cleaning.
