The wife and I bottled a Key lime Pee last night. 2/3rds Key Lime juice, 1/3rd Lemon juice. I used a can of white grape raspberry as a starter. It turned out amazing. Best Pee ever. Much better than our regular Lime Pee (1/3 lime, 2/3 lemon).
*edit* and at 12% ABV, it sneaks up on you and kicks you in the ***... which I am finding out this morning at work. :-D
