Here's a novel idea for those of you interested in homebrewing. When you get grains at your LHBS* it is a good idea to label each bags. I know it sounds radical, but it helps identify which is the domestic 2-row and which is the Maris Otter. Or to identify the 20°L crystal from the 55°L crystal malt.
The last time I went to my LHBS, I got about 20 pounds of grains to be used in several batches. At my LHBS, it is a self service deal where one weighs out each grain, crushes it and puts it in a plastic bag. The last time I was there I got into a really cool conversation with another brewer while we were in the grain room. I kept weighing and crushing grains as we talked. However, I forgot to label most of my bags. I wrote everything on a list so the checkout guy knew what I was buying, but I distracted enough to neglect labeling the bags for my own use.
I just realized this a couple days ago and I got really pissed at myself. I THINK I identified what each thing is. I'm most confused about which 10 pound bag is Maris Otter and which is 2-row. In the end, it isn't that critical really, but I won't be making my Irish stout to the correct specs if I guess wrong.
I am a homebrewer. I only do extract and partial mash brewing (right now). I prefer stouts and american pale ales. I am also a chemist. I teach college chemistry. I prefer organic chemistry and biochemistry.
