Overview
A kitchen counter with a batch of pickles or a small brew going is where this wide mouth glass jar belongs. The twin bubble airlock lets gas escape while the lid stays closed against air.
A clear glass jar with the airlock already in the kit, suited to anyone trying fermentation at small scale. The wide opening makes loading simple. It has no spigot or stand, so transfers are done by pouring or siphoning.
Who it's for
Home fermenters running one gallon batches and wanting to watch the jar contents through clear glass. Brewers needing a conical or a spigot fermenter, or a bigger volume, need a different vessel.
Pros and cons
- Wide mouth opening
- Clear glass body
- Twin bubble airlock included
- Scratch resistant finish
- Hand wash only
- One gallon size only
- Airlock size not listed
Performance notes
The airlock is the working part: it lets fermentation gas out and blocks outside air from coming back in. The clear glass shows activity in the jar, and the wide mouth lets you reach in to load and clean. Nothing in the listing covers temperature control.
