Oak barrels have been used for centuries to manufacture quality spirits and wines. The flavours created by Oak barrels are believed to be very relevant to the region where the oak was grown. The American Oak barrels offered by Brewing Supplies Online are exposed timber barrels. They will impart colour and flavours into either vodka or neutral spirit. With the addition of homebrew additives the brewer may craft unique, quality, spirit. They may also be used to oak condition pre-flavoured homebrew spirits.
