The Better Brew Safety Cork has a one-way valve to protect finished wine from spoilage when stored in 1 gallon or 5 gallon vessel, such as a demijohn. It is perfect for use after fermentation has finished when you wish to mature your brew in a large vessel, before (or instead of) bottling it.
Instructions for use
- Ferment with airlock as usual until fermentation has completely finished.
- Rack off into a sterile gallon jar, fit the safety cork and leave to mature in a cool place.
This safety cork will fit most gallon jars on the market. It is designed to allow any excess CO2 to be released, whilst at the same time preventing air coming into contact with your brew. This reduces the risk of oxidisation.
