So I was wondering what kind of difference it makes when you add LME or DME at either the begining of a 60 minute boil (5 gallons) or 15 minutes before the end. From what I can tell this is only a hop utilization thing. So if for instance a recipe only has finishing hops in it, (added at the 15 minute mark) you could technically just do the boil with all ingredients added at once and only boil it for 15 minutes, vs adding the DME and LME at the beginning of the 60 minutes and the hops at 15 minutes, right? I'm really just trying to figure out when I put my own recipes together when to add the DME and LME and then also how much at which times.
Thanks
