New Beer Recipe: American IPA (Updated)

It's been a while since I brewed a batch of beer, and I just realized I've only brewed 5 times this year. Wow, homebrew fail. Looking through my brewing records (I keep records of all my batches in a paper binder and on my computer) I brewed: 21 times in 2006, 7 times in 2007, 3 times in 2008, and 5 times so far in 2009. That's a most unfortunate trend. To be fair, though, the brews in 2007 and 2008 were all 10 gallon batches, so they could really count as twice as many brews. The change in frequency is pretty easy to explain (though there's no good excuse, I know...), I quit grad school and went looking for a job. I moved to Rochester in February 2007 and didn't brew again until I had my all-grain setup put together. It's tough finding the time to brew, especially when I have to brew alone, with a full time job schedule, and lots of travel on weekends because Rochester sucks.

Well, I have 5 months left to get my brewing back on track. I'm going to start this weekend with an American IPA. For reasons that elude me, I've never brewed an IPA of any sort. My tastes tend to keep me more focused on Belgian and English styles, and typically maltier styles. I've always brewed a lot of English Bitters, as that's my favorite session beer style. Various types of stouts are also frequently in my queue. Now it's time for some good American hop action.

My first cut at the recipe is below. I don't know the exact alpha acid content of the hops, but I'll recalculate once I buy them and find out the numbers. The alpha acid contents I'm using below are my best guesses.

American IPA:
Malt
- 1.00 lbs Light Dry Malt Extract
-10.00 lbs U.S. 2-row Malt
- 1.50 lbs Vienna Malt
- 0.50 lbs Crystal 20L
- 0.25 lbs Wheat Malt

Hops
-1.00 oz Amarillo (8%AA, 60 minutes)
-0.75 oz Simcoe (13%AA, 30 minutes)
-0.50 oz Amarillo (8%AA, 30 minutes)
-0.75 oz Simcoe (13%AA, 5 minutes)
-0.50 oz Amarillo (8%AA, 0 minutes)

Yeast
Not sure yet. Depends what they've got. Probably Wyeast #1272 American Ale II

Mash
152 degrees for 60 minutes, most likely. Might go 150, not sure yet.

[Update]
After going to Beers of the World to buy ingredients, the recipe has been forced to change slightly:
-They had no light crystal malt, so the Crystal 20L will now be replaced by Crystal 40L
-Simcoe hops were sold out. This will now be an all Amarillo IPA with the following hop schedule:
-1.50 oz Amarillo (60 minutes)
-1.00 oz Amarillo (30 minutes)
-0.50 oz Amarillo (5 minutes)
-1.00 oz Amarillo (0 minutes)
-This batch of Amarillo is all at 8% Alpha Acid content.
-Yeast selection was extremely thin this time (which is rare for these guys). No Wyeast 1056 or 1272, so I picked up the only American yeast they had: Wyeast 1332 Northwest Ale.
