And, come to mention it, what's this "efficiency" I see mentioned here and there?
Seriously, Will, with all due respect to you, first of all you seem to be forgetting Charlie Papazian's rule (RDWHAHB).
There are two major decisions I have made in my life that I am very, very happy about. The first was refusing to keep score in golf ever again. It is so much more relaxing to walk a beautiful golf course hitting that pretty little ball around the links without ruining it with the stress of knowing how poorly I'm doing.
The second, more recent decision, came when I started brewing. I know this is heresy around here, but I never use a hydrometer. I have no idea what my OG is or my efficiency or anything like that. I just brew beer and drink it. For me, beer is not science (although I know there is a lot of science involved), but it's really just cooking as far as I'm concerned. I do it for two reasons. First, because I enjoy the process and second, because I enjoy drinking the results.
As long as I like the beer I make, I'm happy.
As for how AG batches compare to extract, my first batches seem to be turning out better than my extract brews did. I've been trying to keep things simple and to use good ingredients (two of my first three batches were made with Maris Otter as the base malt).
If your beers are not coming out strong enough, why worry so much about efficiency? Why not put a little more grain in if your cooler is big enough or put a little extract in your boil?
On the other hand, if someone gets enjoyment from trying to wring every last bit of efficiency out of a pound of grain, more power to them. But Will, you don't seem to really be enjoying that very much.
Keep on brewing, though!
