After years of ales in brewing my first lager based on the recipe in Brewing Classic Styles. I'd like to keep this simple if I can but I don't want to risk a bad batch. The recipe calls for a fermentation temp of 50. Assuming my A419 is working I should have no issues. But should I worry about changing the temps asking the way or can I just keep it at 50 for 3 weeks? If I can keep it at 50 then I could also make a second batch next week and put it along side the first batch.
