Also, I did some posting/research here a while back on new distilleries in KY. While doing that, I also saw a (relatively) new distillery in SC that focused on using technology to "refine" spirits. One of the benefits was said to be rapid 'aging' of bourbon. I remember looking them up briefly and hearing good things, but you never know what to believe without sampling for yourself! Company was called Terrassentia.
Cjen, I recommend reading the threads regarding Cleveland Whiskey who is also using a process to quickly "age" bourbon and have already released their first batch to the market.
