I have a tendency to make 1 gal batches to test different recipes, and I have learned that cutting a 5 gal batch down to 1 gal recipes doesn't always translate well in terms of hop additions. Does anyone have any words of wisdom? I know I should be adding less than what the recipe would call for at 5gals. I keep getting a metal taste to my small batches.
