Viski Liquor Aging Refill Sticks are a set of two charred oak inserts made for use with the compatible Viski Liquor Aging Kit. Each stick fits into the kit's integrated stopper and pourer, allowing the wood to remain suspended inside a bottle of whiskey, bourbon, rum, or another spirit. Contact with the charred oak adds barrel-inspired color, aroma, and flavor over time. The refill sticks provide an alternative for continuing the aging process without purchasing another complete kit.
