US Patent 10184098 Wooden vessel for the aging of liquid

A uniquely designed rectangular vessel has been developed for storing and aging liquids—commonly wine and spirits. Its economical and simplistic design offers significant benefits over the use of traditional barrels and other previously proposed arts. Constructed from wood (generally oak), its inner surfaces have been modified to maximize end grain exposure thus significantly reducing the required aging period. In addition, this vessel's inner surface area to volume ratio (directly related to the wood's extraction concentration within the liquid) can be adjusted to meet the user's specific needs.
