I have stuck with ales in my early brewing career. I think I have 8 all grain under my belt. I brewed a weissbeir and kegged it on Saturday. I thought the wort tasted fine (a little sulfur) and I tasted it again after the secondary no sulfur. I cold crashed it in the secondary for three days at 35. I kegged and force carbed it on Saturday and got a taste on Sunday and it tasted horribly of canned corn and cabbage. Couldn't get the taste out of my mouth all afternoon. Did I just not boil it hard enough?
