I have been helping a buddy brew some beer for his wedding reception and we went to bottle our last batch and opened the lid on the bucket of a blackberry wheat to find this. We went ahead and racked it to the bottling bucket and were careful not to get anything from the top layer. I tasted a little of it from the bottom of the bottling bucket when we were done and it didn't taste bad. However, I am relatively new to brewing and had not had anything that looks that bad. I imagine its some sort of Lacto infection ??? We have a month until the reception and plan on tasting it before and seeing how it tastes. Is it safe to drink if it tastes ok?
