A genuine wooden barrel doesn’t use glue or nails in construction, so sometimes leaks happen from the head or stave seams or even through the wood. This can happen with any barrel and is a normal part of the barrel-aging process

Solve the problem painlessly with this little pot of easy to use Barrel Wax. Just wet your finger and apply a small amount of wax wherever the hole or leak has formed, and then push the wax into the hole with your finger until the flow stops.
