Bought two slap packs of american ale yeast one week ago, came home and brewed that day, used one pack then managed to forget to refrigerate the other one. Its been sitting in my living room at around 68 degrees for a week. Is this slap pack still good? I'd like to save the 6 or 7 bucks I spent but don't know if it is worth it. It looks a little inflated. Thanks for the help.
