One Gallon Clear Glass Jug

This 1 gallon narrow-neck glass jug fits #6 rubber stopper, or 38mm screw caps. We do not recommend using this for primary fermentation of 1 gallon beer batches, as it will overflow with krausen. Instead, use for secondary fermentation or bottling. For primary fermentation, we recommend using a 3 gallon carboy or a 2 gallon fermenting bucket.
