Best of all, you'll have clearer beer, wine and mead. The Screw on lid has a pre installed airlock hole with a fixed silicon grommet and just a gentle push will hold the airlock tight in place. The fermentation bucket is food grade and can be used for acidic foods like kimchi, kombucha etc. Make your brew day easier and your beer better with the siphon less 25 litre bottling & fermentation bucket.
