Garuda (Espresso) Porter

I'm having a brew party coming up pretty soon, so I thought the wife and I should brew up something fresh for everyone to taste when they arrive at our place to mash in with us bright and early on a Saturday morning. What could be better than a coffee porter to wake everyone up?

I've had a few email requests to post the weights of grain I'm using in these recipes. I usually get right around 75% efficiency in my mash tun, so if your system hits right around there too, then go ahead and try the same numbers. If you get a higher or lower efficiency, then you'll need to adjust the amount of grain you're adding. If you only want to brew 5 gallons, then half everything and you'll hit 5.5 gallons. So, from now on I'll try to remember the weights and the %s in each post.

For an 11 Gallon Batch:

Grain:
76% British Pale Malt (19.8 lbs)
9% Munich (2.3 lbs)
9% Crystal 40 (2.3lbs)
3% Carafa II (.78 lb)
3% Chocolate Malt (.78 lb)

Single Infusion Mash:
Saccharification rest at 68 degrees C (155 F) for an hour.
Sparge at 75 C (166 F).

Boil:
90 min. boil

Hops:
2 oz E.K. Goldings added at 60 minutes.
2 oz Cascades added at knockout.

Yeast:
2.5 liter, 2 day starter of 2 vials of White Labs (WLP001) Cal Ale Yeast.

Predicted Original Specific Gravity:
1.065

Notes:
Ferment at 18 C (65 F) for one week or until primary fermentation dies down, bump the temperature up to 21 C (70 F) for another few days and let it finish off. Then keg it up and add 1 oz/gal of Peets Garuda Espresso (my favorite espresso in the world).

UGH. That was the most disastrous brew session I've had in a long time. For some reason I ended up with about 40% efficiency. I think there must have been a portion of the mash that got itself stuck during sparge and it ended up channeling. I don't know, but I stopped the sparge at around 9 gallons and ended up with 7 in the end and hit about 1.061 OG. I adjusted the hop schedule accordingly, but at the last 15 minutes of the boil I ran out of propane. So... it might be a little low on IBUs. With all that said, it smells great and will probably turn out to be a fine, drinkable beer. But, what a mess of a brew day. I hope the next session goes a little more smooth.

EDIT: I screwed up the numbers... new weights, total grain should equal 26 lbs for 11 gal (not the previously posted 32! :)
