Carboy - 1/2 Gallon Glass Growler Fermenting Kit with Airlock

  • $7.73

1/2 Gallon Glass Fermenter - Perfect for small batch brewing. Fits the included #6.5 bung/airlock. Crystal clear for easy visibility.

The 3-Piece airlock is the best choice for the primary fermenter, since it comes apart for easy cleaning in the event of a blow-off. Fill to the line with boiled water or sanitizer to create a closed fermenting system that allows CO2 to escape, but does not allow air back in to contaminate your beer or wine.
