Citrarillo IPA (American IPA with Amarillo and Citra hops)

Last week I brewed an IPA where I set out aiming for a west coast style (lighter bodied, dry, and excessively hoppy). I'm a big fan of IPAs that have a strong citrus hop flavor and aroma, like Ballast Point's Sculpin. To achieve something like this I decided to use only Amarillo and Citra hops. This is my first time using either hop, but reading up on each it sounded like they would met my needs perfectly. Amarillo is a dual purpose hop that delivers a clean bitterness, which is what I was looking for since I wanted this beer to be more of a showcase for hop flavor and aroma. I've seen the amarillo flavor described as grapefruit, but in all the commercial cases I've had as well as smelling the hops I've always thought they have more of a tangerine and mango flair. I also paired the amarillo with citra hops in the late boil and dry hop additions for flavor and aroma. The citra should add even more tropical fruit flavor to the mix.

As for fermentables I'm constrained to using extract to brew due to my apartment size. I kept it pretty simple with extra light dry malt extract, sugar, and carapils. I'm developing a mild hatred for caramel malt in IPAs so I left that out. I added the pound of sugar to get the FG down and add dryness. This was done at the end of the boil to keep my hop utilization up. In an effort to keep as much hop aroma as possible around I also added a stirring component when chilling the wort. I used my wort chiller like normal, but left a spoon in during the last 20 minutes of the boil to sanitize it. Once I had the wort chiller going I would periodically stir. This really sped the cooling step up since I was able to displace the cooled wort from around the coils with hot wort from the middle of the kettle. The wort temperature was down to 75F in under 10 minutes by far the fastest time I have achieved.

This was my first time fermenting with American Ale II, but with a 1 L starter that was intermittently shaken for 24 hours the fermentation took-off in under 12 hours once pitched. The hop aroma that was coming out of the fermenter when the air lock was active was intoxicating. The FG landed at 1.008 after 5 days (the OG was 1.053 instead of the 1.056 I was aiming for). I transfered to the a secondary and added in the dry hops.

I stole a sample when transferring to see how the beer was progressing and it was terrific. The color is a little lighter than I expected, but that isn't such a big deal. The citrus aroma is very strong even before the dry hops were added. The taste was had a strong but mellow bitterness and tons of tropical hop flavor (tangerine, mango, pineapple, and orange). Hopefully this awesome hop profile holds up! I'll add tasting notes after this is bottled and carbed.


Here's the recipe.

UPDATE: 2/28/2011
I just transfered this beer into a tertiary fermenter since I won't be able to bottle for a few days and I didn't want it sitting on the 4 ounces of dry-hops that long. The tropical hop aroma and flavor is crazy now. It's too bad I have to wait another 2 weeks before I have this beer bottled and carbed.

Exciting News from the Alchemist Brewpub!


                                       http://www.alchemistbeer.com/cannery-announcement/


Follow the link to the news on the Alchemists progress on setting up a canning line. Looks like Heady Topper will be available in cans some time this summer at a new retail shop at the brewpub! Heady Topper is one of the best beers I've ever tried. It is worth the drive to Waterbury, VT to just get it on tap, but soon you'll be able to take some home with you too!
