Extra Fermenter Kit

Expand your fermentation capacity with the Extra Fermenter Kit from Craft a Brew, a compact one-gallon fermentation setup designed for homebrewers, winemakers, cider makers, and mead makers. This reusable fermenter bundle includes a glass carboy, 3-piece airlock, rubber stopper, and transfer tubing, making it easy to run multiple fermentations side by side or experiment with different yeast strains, flavor additions, and fermentation conditions. Ideal for small-batch brewing and split-batch testing, this setup helps brewers increase flexibility without investing in a full second brewing system.

Designed for one-gallon fermentation projects, the Extra Fermenter Kit supports beer, wine, hard cider, mead, hard seltzer, kombucha, and other fermentation experiments. Brewers can divide larger batches into separate fermenters to compare yeast performance, aging methods, adjunct additions, or fermentation temperatures.

The included glass carboy provides a non-porous fermentation vessel while the 3-piece airlock allows carbon dioxide to escape during active fermentation. Transfer tubing can also be used for blow-off setups during vigorous fermentation activity.

Widely used by homebrewers expanding their setup or experimenting with new fermentation techniques, the Extra Fermenter Kit provides a simple and reusable small-batch fermentation solution.
