While allowing the right amount of oxygen molecules to permeate the vessel's sidewall, Bulk Barrel's proprietary design is virtually impermeable to water and alcohol vapor, which eliminates the leaking and routine topping requirements associated with oak barrel maturation. The seamless one-piece interior construction is much easier to clean and sanitize before reuse which eliminates the routine repair and maintenance costs created by aging oak barrels.
