i've got an IPA in a 5.25 gallon american oak medium+ toast balcones blue corn whisky barrel as we speak. i'll let you know how it turns out!
i loved the oaked ipa i tried (commercial).
Nice...I'm curious to know how it turned out. I've thought about doing exactly what you're doing but never got around to doing it.
we are kegging it in a couple days. i'll be sure to let you know. the ipa is actually closer to an imperial ipa at about 7.5 - 8.0%, 101 ibu. hopped with chinook, centennial, amarillo & magnum.
