"Every bottle is its own learning experience." -- Sensei Ox-sama
Wood for wine barrels are usually 36 month air died. But wine barrels are normally 63 gallons. They sand them up nice and charge at last i checked, about 900 bucks a piece. Where a nice bourbon barrel of the same wood, charred, 135.
Of course a wine barrel will be reused vintage after vintage and with proper maintenance can last 50 years or more.
