I brewed this beer as my sixth batch: http://www.homebrewtalk.com/f64/pyrr...ory-esb-70129/
The only deviation from the recipe is that I let it sit in primary for ~6 weeks. I broke my thumb shortly after my brewday, and I had to wait for the cast to come off before I could bottle. Also, the recipe did not list a dryhop time, so I dryhopped for one week. Unfortunately, I forgot to get an OG/FG, but every brew I've had so far has been within +/- .03 from listed recipes, so I'm sure I was close.
The beer is good. However, I like my ESBs to have bigger mouthfeel and a slightly maltier character. This beer is just a little dry for me. This is something I'd like to start messing with.
Since I'm pretty comfortable with the mechanics of brewing extract by now, I would like to start getting away from simply following a recipe. I would like to start by modifying this recipe into an ESB that suits my tastes a bit more. The problem is that I have no idea where to start. I have no idea how different hops/extract/etc. will change a beer. For instance, if I change from light to amber, lme to dme, 6.6lbs to 8lbs, EKG to Citra, or any other minute change, I wouldn't be able to predict the result.
Is there anywhere I can go to get a primer on this sort of knowledge? If not, can someone at least point me in the right direction for modifying this particular recipe?
