Jakemo's Centennial Single-Hop IPA

[Jakemo]

Following in the footsteps of my Amarillo Single-Hop IPA, I've tweaked the recipe a little bit. The Amarillo IPA was very good overall, but there were a few things I felt needed adjusting this time around. I want a little more malt flavor, as the malt profile of the Amarillo is very much subdued and in the background.
Also, the aroma of the Amarillo at 4 weeks was probably about 40% of what it was at 3 weeks in bottle. That may be due to the fact that I lost a lot of hop oil through blowoff (the freaking tube was stained green) or just a natural side effect of bottle conditioning. Either way, I've adjusted the hop additions to be no earlier than 20 minutes to really focus on flavor and aroma. The final adjustment was going with 1# less LME and adding 1.5# 2-row as my first attempt at a mini-partial-mash.

Safale US-05 cuz I'm comfortable with it and like what it's given me so far.

Will update as I brew and bottle and taste and drink repeatedly.
Anybody have any recommendations for the method? The recipe's pretty much set, with the exception of the hop addition times. Thanks!

Brewed yesterday. Looks good, siphoning from the pot to the carboy took a worryingly long time...
Tasted wort after mini-mashing grains. Tasted sweet, not starchy. Conversion should've worked well enough.
Measured OG after shaking, 1.050. Probably not mixed well enough with the water.
Pitched yeast at 70F. 1 dry packet US-05
With other beers, getting some airlock bubbling by the next morning, this one's not there just yet. Looks crazy in the carboy; lower half is lighter (I'm assuming from proteins settling), upper half is darker. 1/2" thick layer of foam on top, we'll see what it's doing tonight when I get home.

Looks good, man.

I brewed a partial mash SMASH APA on Friday using Marris Otter, Light DME and Centennial throughout. Shot for 1.050 but it ended up being 1.045 after a good shakin'. I think with top-off water, you just have to assume you'll be a little low on the OG, which probably means you were right on. My gravity sample tasted pretty bitter, but you really can't predict much from that initial dose. I went with the US-05 as well and it was still fermenting actively when I last checked on Sunday evening.

Let us know how it turns out.

Sounds good, Patty. I had a Centennial session beer at a brewery here that was just Vienna malt and Centennial hops. It was outstanding, Centennial is a pretty awesome hop. Cheers!

Started another thread cuz the fermentation was funky (read: not something I was used to; different; therefore RDWHAHB). Stopped at 1.014 after 10 days in primary. Racked to secondary, added 1 oz Centennial pellets. Gonna sit for 10 days before I bottle. Tasting decent, can't wait for cold and carbed!

I just used US-05 for the first time, too, and the fermentation has been very strange; not what I'm used to, and from the sound of things, nothing like yours! I had massive activity about 5 hours after pitching directly, with all kinds of chunky stuff floating up and down and a good 3 inches of foam! I tasted it to make sure it wasn't infected, and it was totally fine. A week later the airlock activity is down to a sane big bubble every minute or so, but it hasn't flocced nearly as much as I hoped it would. Haven't tested the gravity yet, but it started out at 1.070, so it may need some more time before the secondary... Good luck with your brew!

 

[Jakemo]

Ha! That's the kind of fermentation I'm used to, very vigorous, and very soon after pitching! Vive la difference, oui?

 

[PattyC]

I've used US-05 quite a few times and there's always a pretty good fermentation. Nothing like you'd see with a wheat beer yeast, I imagine (I haven't brewed a wheat yet), but active nonetheless. I used it on my last pale ale and it came out really clean. Think it's going to become my first "house" beer!

 

[Jakemo]

After being refrigerated for a number of weeks, this beer ended up being a delicious pale ale. Not quite IPA but very tasty nonetheless.

I'm definitely learning the value of cold-conditioning through these single hop beers!
