What You Need for a 1-Liter Batch
Tools:
- 1-Liter Oak Aging Barrel – Get yours from Red Head Oak Barrels
- Measuring cup & funnel
- Glass bottles for storing after aging
Ingredients:
- 750ml Irish Whiskey – We recommend Jameson Black Barrel, Redbreast 12, or Tullamore D.E.W. for their smoothness and character.

- 100ml Water – Helps blend the ingredients for aging.
How to Barrel-Age Your Irish Mule
Step 1: Prepare Your Barrel
Before adding your cocktail, your small oak barrel needs to be conditioned:
- Fill the barrel with warm water and let it soak for 24-48 hours to prevent leaks.
- Drain the water and let the barrel dry completely.
Step 2: Mix Your Irish Mule Base
- In a mixing pitcher, combine the Irish whiskey, lime juice, simple syrup, and water.
- Stir well to ensure all ingredients are fully blended.
Step 3: Fill the Barrel
- Using a funnel, carefully pour the mixture into your whiskey aging barrel.
- Seal the barrel with the bung and store it in a cool, dark place.
Step 4: Let the Aging Begin
- Aging time: 3-4 weeks for a balanced, well-integrated flavor.
- Taste-test weekly to monitor its development.
- Once it reaches your desired smoothness, transfer it to bottles to prevent over-aging.
How to Serve Your Barrel-Aged Irish Mule
Step 1: Mix with Ginger Beer
- Fill a copper mug or highball glass with ice.
- Pour 2 ounces of the aged Irish Mule mixture over the ice.
- Top with 4 ounces of ginger beer (we recommend Fever-Tree or Q Mixers for a crisp, high-quality finish).
Step 2: Garnish & Enjoy
- Garnish with a lime wedge and fresh mint sprig.
- Stir gently and enjoy the smooth, spicy, and citrusy flavors.
Pro Tips for the Best Barrel-Aged Irish Mule
- Choose a smooth Irish whiskey – Mellow options age best and complement the ginger and lime.
- Taste-test frequently – Start sampling at 2 weeks and adjust the aging time as needed.
- Rotate your barrel – Give it a gentle turn every few days to ensure even aging.
- Reuse the barrel – After aging your Irish Mule, try using the same barrel for an Old Fashioned or Manhattan for an added depth of flavor.
