Hi there, I made an all grain weiss beer on Thursday. The OG was 1.050 and today (Saturday ) it is 1. 031. I am keeping the fermentation temperature at around 18 degrees Celsius. I used safale WB06 yeast. The banana flavour/nose is already very prominent almost a bit much. Will it tone down when fermentation is complete? Also why has the gravity dropped so rapidly? I have made quite a lot of Weiss beer and have never had any of the above happen so am keen to know what caused this. Is my beer going to be good or am I sitting with a possible wasted batch?
