After a couple of years on hiatus I have begun to brew again. This time around I have moved to all grain but have run into problems. Each batch I have attempted has been infected. The first batch had the white bubbles and film in both the fermentor and bottles. Depending on the day I had at work this batch was drinkable. I decided not to give up and tried again. With each attempt I researched methods for proper sanitization. This time around I have looked at the fermentor and see large white clumps floating on the top. The white clumps look like icebergs. In addition, the fermentor has been bubbling for about a week. Is it safe to say that this batch will be a sacrifice to the beer gods? Thanks.
