Just a curiosity question..... After you crack your grain how long do you wait if at all to mash your grains? more specifically I was at my lhbs today and picked up appx 10 lbs of grain... I don't have a mill so I had him crush my grain only problem is I probably won't brew until wensday or thursday..... is that ok? maybe I'm just being paranoid or maybe there is merit to my concern and to you brewers more knowledgeable than I .... I pose this question.
