Hi, as the weather isn't particularly hot at the moment, I have decided to keep on brewing after initially stopping for the summer. With my latest IPA brew today, I have decided to try a brew with a 60 minute mash (grain bag steep) as opposed to my usual 30 minutes. I am not sure what difference this will make if any? My next brew, I will use exactly the same recipe but will step for 30 minutes and compare the brews myself. Thanks in advance.
