I loved all bourbon every the not good ones until this turd came along. I could always find something about a bourbon that I like even if its weak and low proof. I dont know what it is I'm assuming their yeast strain but I absolutely positively did not like it. Even giving it time to open up made things worse. The extra kick in the nuts was it ruined my pallet making a 40$ pour of Jos. Magnus Cigar blend #23 also taste bad. ( had the cB before and since I know its great)
