I have brewed a couple of variations on this recipe and love it. I craved more chocolate character after my first batch, so I upped it by 3x - then I realized that the first time I had used pale chocolate malt, and the batch with 3x was normal chocolate malt, oops. So, this version came out very dark and with a nice touch of roast character (and lots of chocolate!).
I loved the beer but wasn't sure how to enter it into a comp, so I entered it twice - as an American Brown Ale (10c) and as a Robust Porter (12b). I ended up taking 3rd place in the 10c category with two 35/50 scores. In the 12b category I received an average of 29/50. Both category's judges commented that I was nearly out of style, either too roasty for 10c or too hoppy, thin-bodied, and lacking roastiness for 12b.
Here is my variation on the recipe. The tettnanger sub was due to availability, but the hop character did not change drastically from the first batch with willamette.
