I've only done extract kits before, but I'm planning to move ahead into all grain. I was going through a recipe I want to try and found all the ingredients from a single online vendor. It looks like my LBS doesn't have the variety of hops that I'm looking for. However, the shipping charge is a little steep for a single order. So, how many brews do you guys plan and by ahead of time? What system have you guys developed? Do guys buy in bulk?
