I really enjoyed 1 gallon brews, but there was never enough beer! Yes definitely do 60 minute mash. 60 minute boil. Try not to boil too vigorous, I would sometimes have to dilute mine after the boil, which is not a problem, its just another step to take. Cool down, I would fill my sink with ice and water, probably 15-20 mins to cool 1 gallon if you stir the whole time. Hey- if you are doing pale ales and like hops, put like tripple the aroma hops (5 minutes until flame off and 0 minutes, dry hop too), you can never have enough. I do 10 gallon batches, and it can get pretty expensive when I am using almost a pound of hops at a time, 1 gallon batches are great to load up with aroma hops, you wont regret it.
