Bell's Two Hearted clone. Followed the recipe to the letter, and it turned out technically a good beer....but I hated it. Grassy grassy grassy piney yuck. I like piney in moderation but could do without the grassiness I got from the Centennial. It was also dry as a bone, bleah.
And other than abject failures when I was first learning, I've brewed two for a friend that I won't touch with a 39 1/2 foot pole; one brewed with jalapenos and the other with habaneros. He loved them but....eeew. I still have some bottles that I can't get rid of.
