Hey so I have one brew with extract under my belt, hoping to taste the end result in a few days. Getting ready to do my first brew that'll have steeping grains and I have some questions/concerns. One of the grains I'm using I'll be using the entire amount I purchase so I'll be buying it milled. The other 2 though I'll likely have leftover so I'm assuming it's best to keep it whole till I use it. The thing is I don't have a mill. Planning to buy a Corona mill at some point as I move towards BIAB but buying it now really isn't an option. My wife seems to be getting a little fatigued from my equipment purchases so I figure I should cool it for a while. I'm figuring my best options without a mill involve a Ziploc bag and some kind of hammer (meat tenderizer?) or maybe the food processor but just do like a few quick pulses? Or should I have the store mill it all for me?
