The yeast may change depending on what my LHBS has in stock. I think I'm also going to use a Sumatra coffee and do it cold steep, then rack onto it in secondary. I was also thinking of mashing a little higher than 150° F (like maybe 154° F), would this be better? I'll let you know how it turns out!

Mashing a bit higher could certainly complement the coffee. Otherwise the recipe sounds great.

I've had the best luck adding the coffee beans directly (either whole, or coarsely ground in a muslin bag) to the beer for 12-48 hours right before bottling/kegging. That method seems to impart more complexities and the flavor/aroma lasts longer than adding cold brewed coffee.

Good luck brewing.

I'll be starting this in a couple hours. Got everything ready to go. I ended up going with WLP002 instead of the wyeast, since that's what my LHBS had available. Made a small (2 cup) starter so it will take off shortly after pitching. I'm going to try to tweet updates as I go along, so follow @Beehemel if you want to stay in the loop!

Just finished this one. Came out pretty good! OG was 1.061, better than I was planning (only by two points). Smells and tastes pretty good so far, can't wait to see what fermentation and the coffee adds to it!

Put the coffee in the fridge to cold steep on Saturday, planning on racking with the coffee tonight. I ended up going with 4 oz of coffee to 4 cups of boiled and chilled water. Should I sanitize the coffee filter before I run it through tonight?
