I've noticed a post here or there about how hefe yeast loses flavor after a couple re-uses, and I was wondering what people thought about this? I recently brewed a hefe, and it turned out so great I want to make it my house beer, but I don't want to do that if I have to buy yeast every other batch. I'm most interested in WLP300, but I'd like to hear results on other weizen yeasts as well.
