The first time I did this, I made the mistake of not making a yeast starter. It took 3 weeks to get down to 1.020 in gravity...and probably didn't attenuate completely due to under pitching. This contributed to a sweeter IIPA than is typical for the style, but I have to say still VERY tasty. But next time, I'll be brewing a house pale ale or amber ale, and pitch directly onto the yeast cake. Alternately, make a 2-3 liter starter 2 days before pitching. Pitching a larger starter and using the 2# of corn sugar will help the beer reach a lower FG for a dry finish.

The dry hop of just 4 ounces is surprisingly strong and quite aromatic. I think the full 2 weeks of dry hopping ensures that all of that hoppy aroma is sucked into the wort. I used whole leaf hops, since that what was readily available and was definitely pleased with the aroma...and ease of racking out of the secondary. For the first time brewing this, I'd have to say I'd give it 85/100 for a taste rating. Next time with adjustments to the yeast starter I think this recipe will be a home run.

You probably know this but, I have read that US-05 is the same strain as Wyeast 1056. I have had really good luck with both US-05 and Nottingham for IPA's and IIPA's. I used 1056 once. I'm lazy and don't like making starters. :D

I think I will only use liquid yea$t for Belgians.

Yeah, I should try Safale...haven't dabbled with that yeast yet, but I love Nottingham. Next time I brew this (next month I think), it will be going on top of a yeast cake of Nottingham from my Amber Ale. Should be an explosively good time :D!

That looks like one KILLER of a beer. My IPA is entirely centennial. I'm ape**** over that hop. I love it. :mug:

Yeah, the centennial in addition to the cascade was very good for the dry hop. I was worried the two would clash, but the citrusy aroma is just killer and I think stands out a bit more than just Cascades. Actually, centennial is becoming one of my favorite all around hops!

Is it possible to mash this recipe in a standard 10 gallon chest-style cooler?

Will do. I need to get some bulk maris otter in so these tasty imperial brews I'm getting into don't cost so damn much to brew :p The russian imperial stout I made last weekend cost a ton but damn it'll be worth it!

Next up for me is an IIPA kinda similar to this, and I have a question for you. Why do you recommend not mashing out? What does that do / not do to the final product?

It basically extends the length of the mash to include your sparge time. By mashing longer you ensure that conversion is complete, and it also tends to help lower your final gravity.

1# of CaraPils would do the trick. I just wanted something in there for some body and head retention while not affecting the flavor. I have a ton of bulk white wheat malt which is why I use it frequently in place of CaraPils.

Cool. I'm going to be buying a pallet of grain soon (may start carrying kits! I know kits arent very big for ag brewers due to efficiency and personal recipe creation..but still) and am looking forward to having maris otter in there so I dont spend like 90 bucks like I did last weekend forthat RIS..lol and the Rogue Imperial Stout I drank while BREWING it was another $14....$14 well spent (worth the kickass botle).

Just out of curiosity, what software are you using to generate these recipes, calorie, efficiency numbers? I like the format and I'm been looking into some software. Thanks.

Can I ask why the centennial hops are broken up into two 1 oz groups for the dry hopping?

Thanks

I brewed this recipe and I am getting no carbonation at all. I think all the yeast have died because the alcohol content is so high.

Also this is some DARK beer for an IPA. I cannot see through my glass!

Also the taste of alcohol is noticeable.

I'm also interested in this question. Are the dry hop additions meant to all go in for 14 days or 14 days for each addition?

I'm gonna give this a crack tomorrow.... anything I should be aware of?

I've made a 1ltr starter out of one packet of US05, and I will pitch that, along with another whole pack of US05... hopefully that gives me the attenuation I need.
