Quick question for the people in the know, I am looking at an extract brew recipe, but one of the ingredients have me a little puzzled as to what it means:
6lbs Light Dry Malt Extract added to the boil
1lbs Crystal 60 add the grains to the water and steep until the water temp reaches 170 and pull them out.
The 1lbs Crystal 60. I know the grain/malt is crystal, but what does the 60 mean?
