Brewed my first self-designed batch the other day, a California Common. Went pretty well, used my new 10G kettle and 55K BTU burner for a full-volume boil and my new "ghetto-look" immersion chiller. Took my OG reading, nailed my target, and was feeling like I was starting to get this brewing thing down. Then I tasted my sample and WHOA! Much more bitter than I was anticipating. Oh well, maybe it'll mellow I figure. Then I was playing around with my new copy of Beersmith and setting up my equipment and noticed when I plugged in my 10G pot the IBUs on the beer I was playing around with went through the roof! That was when I learned that hop utilization is much higher with a full-volume boil. Sigh. Now I've got some hopped-up Frankenbeer and I'm not sure how it's going to turn out.
TL;DR: Discovered the hard way that hop utilization is higher with full-volume boils.
