Barrel aging is central to premium wine production in the US. From Napa Cabernet Sauvignon to Willamette Valley Pinot Noir, the barrel program defines the wine's character and represents a significant cost that must be tracked accurately.
Barrel Inventory
Each barrel should be tracked with:
- ID: number, barcode, or QR code.
- Type: barrique (225L/60 gal), puncheon (500L), hogshead.
- Oak source: French (Allier, Tronçais, Nevers), American, Hungarian.
- Cooper: manufacturer.
- Toast level: light, medium, medium+, heavy.
- Purchase date and cost.
- Number of uses: 1st, 2nd, 3rd fill.
- Status: in use, empty, being repaired, retired.
Content Tracking
For each barrel in use:
- Wine: variety, vintage, lot.
- Date filled.
- Expected removal date.
- Last analysis (SO₂, VA).
- Tasting notes.
Topping (Ouillage)
Barrels lose 2-5% volume annually through evaporation (the "angel's share"). Regular topping (every 2-4 weeks) prevents oxidation. Each topping should be logged.
Barrel Costs
- New French oak barrique: $800-$1,500.
- New American oak barrique: $400-$700.
- Amortization over 3-5 fills: $160-$500 per use.
- Evaporation loss: 5-15 liters/barrel/year.
- Labor: racking, topping, monitoring.
- Storage: cost per square foot of barrel room.
For a premium Cabernet with 18 months in new French oak, barrel cost can be $3-$5 per bottle.
TTB Records
TTB requires wineries to maintain records of all wine movements, including barrel transfers. The cellar treatment record must document:
- Date of barrel filling and emptying.
- Volume in and out.
- Any additions (SO₂, fining agents).
