Oak Barrel Care and Cleaning

Curing Your Barrel

First, rinse the inside of the barrel by filling and emptying 2 or 3 times to remove any wood debris. Prior to use, your barrel must be filled with water for approximately 3 to 5 days. This allows the American White Oak to expand and become watertight. Liquid may slowly seep through the wood for the first 3 to 7 days; keep the barrel topped off during this time. Once it stops draining, rinse one last time before filling with your spirits.

Filling with Spirits

When filling your barrel, ensure it is completely full to remove all air, then place the cork in tightly. Excess air inside the barrel can lead to oxidation and spoil the aging process.

Reconditioning Your Barrel

In preparation for reusing your barrel, especially when aging wine, it may need to be reconditioned to remove excessive tannins. Soak the barrel for 2 to 3 days using a specialized cleaning solution.

For detailed instructions and professional-grade supplies, see our Barrel Cleaning Kit.

Storage & The "Angels' Share"

Barrels should be stored in a cool, dark place away from direct sunlight. Over time, liquid will be absorbed by the wood or evaporate—a natural phenomenon known as the "Angels' Share," typically averaging about 5% over two years.

Maintaining your Barrel

If the exterior shows wear, lightly sand the wood with fine sandpaper and apply a coat of water-based varnish. Remember, barrels left without liquid will dry out quickly. If your barrel has been sitting empty and begins to leak, you must repeat the curing and reconditioning process.

How to Clean Your Barrel:

  1. Mix 4 oz of Barrel-Kleen with 1.25 gallons of hot water. Soak for 3 days, rolling the barrel regularly. Flush 3 times with hot water.
  2. Light a sulfur strip and submerge it through the bung hole to sanitize the interior.
  3. Mix 1 oz of citric acid with 2 gallons of water, swish for 5 minutes, then empty and rinse thoroughly with hot water before refilling.
