Brewed a batch of Dunkelweizen today. While steeping the chocolate & malt, the temp got above 170 for about 3 minutes. It went up to 180 when I walked away for a few minutes and I immediately cooled it back down to 160/165ish. I know it says it will release Tannins if it gets above 170, so what can I expect in 'off flavors' or flawed beer?
