Okay, so I brewed my first extract homebrew about a week and a half ago, currently in secondary. Now I was watching videos on YouTube on brewing processes and immersion chillers and the such, and I noticed that a lot of guys had there boils going at over 200 degrees. For some reason I thought I read somewhere to boil at 155-165 degrees, which is what I did. Is this true? Do you guys maintain a steady boil temp for the hour, or do you just let the boil keep rolling and progressively get hotter over the hour past 200 degrees?
