Ask for availability of the the barrel size and toast level you need. In my opinion these are the best barrels for Cab Sauvignon aging that I was able to find and buy for a decent price. The aroma of Arkansas White Oak is far above any other American oak, which I prefer over French Oak for Cabernet Sauvignon.
Check out Midwest Barrel Co Barrels and I believe code WELCOME10 or 10OFF may get you 10% off too. Their wine barrels are 59/60 gallon size but their bourbon barrels come in 5, 10, and 15 gallon sizes for under $200 per barrel.
