Been following another thread which lead me to this one. Your recipe is VERY close to my porter (glad to see I'm doing something right!)
I'm using Crystal 80L vs. 40 but for the most part our ingredients are pretty similar. I'm a coffee junkie so I ended up adding 10oz of a specific type of coffee (iced tody) to mine. I added the coffee during kegg'ing and it tasted amazing. It was a popular brew amongst friends. The coffee was the perfect amount. I plan on brewing it again but I may add bourbon chips to it as well just to experiment.
Thanks for the great posts I'm very tempted to try your recipe & see how bourbon chips would taste.
On another note, was wondering if you're part of Austin ZEALOTS?
