I live in NYC and belive it or not there isnt a home brew supply store within an hour from me and I dont have a car. So the only convenient way to get supplies is on the internet. My question is: Yeast (especially lager) is supposed to be kept in the refrigerator until it is going to be used, so is buying it online not a good option? It takes about 2 days to get to my house so that means it is unrefrigerated for 48 hours.
