HOW TO CURE, STORE AND
MAINTAIN YOUR OAK BARREL

For great results, follow these stepsHOW TO CURE, STORE AND MAINTAIN YOUR OAK BARREL

An oak barrel needs to be cured before it can be used for aging. Curing can take up to a week but your success depends on it, so don’t skip this step!

It’s a simple process that involves soaking the wood and allowing it to expand. You’ll get a watertight seal since the swelling eliminates small gaps in the wood and gives the hoops a tighter grip. More importantly, it will help you identify any leaks—especially if your barrel is new.

Here are the steps:

  1. 1. Use a rubber mallet to insert the spigot.
  2. You’ll want to flush your barrel 3 times to remove any loose debris. Add water through the top hole and pour it out through the spigot.
  3. Now, fill your barrel with hot water. (Don’t stop, fill it all the way to the top.) Every part of the interior surface should come into contact with water.
  4. Insert the bung and place your barrel on a tray. Let it sit for at least 48 hours or up to 3 days.
  5. Got a leak? Top up with water and continue to let the barrel sit until it stops leaking. A small amount of barrel wax may also be applied where needed.
  6. No leak? Empty the barrel and give it a final cleanse by rinsing it out three times (see Step 2).
  7. Your barrel is now ready. (Next up: How to Barrel Age Your Spirits)

With proper care, your barrel should last you several batches. To prolong its life, use maintenance tablets after every 2-3 batches to sanitize the inside of your barrel and prevent mould (just be sure to rinse out your barrel a few times after this step).

Storing your barrel

Never let your barrel dry out between batches. Seriously. Never.

If you’re not ready to age your next batch, grab a glass of water and drop in the right number of maintenance tablets based on your barrel’s capacity:

  • 1 tablet for our 1, 2 and 3 L barrels
  • 2 tablets for 5 L
  • 3 tablets for 10 L
  • 5 tablets for 20 L

Once dissolved, pour the solution into your barrel and fill it completely with water. Store in a cool place and keep the exterior clean by wiping it down with a damp cloth.

If your barrel does dry out, repeat the curing process. If that doesn’t rescue your dried-out barrel, try submerging it in warm water for a few days; this might affect its appearance, but it may also help revive your barrel.
