Back in March, I made a 5 gallon batch of Hefeweizen for a guy I work with that retired. I had to go out of town, so I gave a friend instructions on what to do with the keg. I have the CO2 cartridge thing. They just put the keg on ice to keep it cool. The party was at the end of May. They only drank about half the keg. Then, the keg was left on the guys back porch until today when I finally got it back. Do you guys think the beer is still good? This is Anchorage, AK and it hasn't been above 70 degrees yet this year. But the temperature has fluctuated daily between the low 40s and upper 60s.
