A friend of mine ordered the beginning homebrew kit from Northern Brewer and upgraded to the Wyeast 3068 for his Dunkelweizen extract kit. Apparently, the yeast was shipped without an ice pack and the boxes have been sitting in his office for a couple of days. We're hoping to brew on the weekend, so I'm wondering if the yeast is still viable or whether we're better off getting a fresh tube from a LHBS.
