The Barrel Aging Process

1. Base Production: Imperial Stout with high ABV (10-14%), complete fermentation, full-bodied and malty.

2. Barrel Selection: Bourbon, whisky, rum, or wine barrels, previously used for spirits (1-3 uses), in American or French oak.

3. Aging: Transfer to barrels for 3-24+ months at controlled temperature with periodic monitoring.

4. Blending: Tasting of different barrels, blending for balance and final adjustments.

5. Bottling: Unfiltered, low carbonation, numbered limited editions.

What Happens in the Barrel

• Extraction: Vanilla, caramel, tannins from the wood; bourbon/whisky residues; phenolic compounds.
• Oxidation: Micro-oxygenation through the wood, maturation and rounding of aromas.
• Evaporation: "Angel's share" — loss through evaporation, concentration of flavors.

Types of Barrels and Profiles

• Bourbon Barrel: Vanilla, caramel, oak, spices — pronounced sweetness.
• Whisky Barrel: Smoky, peaty (if Scotch), spicy — high complexity.
• Rum Barrel: Molasses, cane sugar, tropical — very pronounced sweetness.
• Wine Barrel: Fruit, tannins, acidity — complexity different from bourbon.
