Used wrong bittering hops. Looking for opinions

[BigNastyBrew]

I'm supposed to bitter with 14.4% Magnum for an hour, right? Well, I bittered with 8% Centennial instead. I went to add my "10 minute Centennials" and there are my Magnums....DAMMIT!!!

Fortunately, my pack of centennials happened to be 2oz instead of 1 oz. So, I added the Magnums and centennials at 10 minutes. I still ended up with 63 IBU, but now I'm just not sure how the flavor profile is going to be since I used magnums as an aroma/flavoring hop.

Anyone have any experience using the Magnum hops as a flavor/aroma?

You can think of Magnum as a really intense, high alpha version of Hallertaur.
(Centennial makes a pretty nice bittering hop too, btw.)

(I'm guessing you brewed an IPA based on those varieties, amounts, alphas, and the times you were supposed to be adding them)
You will end up with a good beer. I'm thinking it will be more like a traditional East Coast style IPA - more resinous bitterness but with a lower intensity spicy, floral hop flavor, instead of an earthy British hop flavor. It will still be a nice beer, just different and spicier.
Were there any other hop additions? What, when and how much?

Thanks for the quickness, BDawg!

60 Minute 1oz 8% Cen.
10 Min 1oz 8% Cen
10 Minute 1oz 14.4% Mag.
5 Minute 1oz 11.9% Simcoe
0 Minute 1oz 8.6% Amarillo

I used my Barley Crusher for the first time on this one too and left the rollers at default as a gauge. I got 64% efficiency....So I got a 1.060 beer with 66 IBU (1.099 ratio).

You will NOT get 63 IBUs out of it if the only change was that you reversed 1 oz of Mag 14.4% with 1 oz of Cent 8% at 60/10, but that's ok.

That's gonna be a nice hoppy APA (not IPA). Definitely NOT ruined, just not as bitter as if you had used the magnum at 60.
I think you are gonna really like the hop flavor in this. Those varieties will layer nicely together. Don't sweat this at all. An oz of 8% at 60mins is plenty bitter for an APA, it's just not gonna bitter it up to IPA levels. Off the top of my head without trying to calc it out, this should be somewhere around 45 IBUs.

Thanks! I hope I do like it!

Funny thing is, I was shooting for 66 IBU but with only using 4oz of hops instead of 5oz. It's pretty much the BCS recipe called "Hoppiness is an IPA." Only difference is that I was supposed to use Horizon but my LHBS doesn't have it so I substituted Magnum.

You sure it's not IPA? I'm looking at the numbers in BCS and they're all in there (or is beer smith lying about my IBUs? ). I don't mind if it's an APA, either but the IBU looks high.

[BDawg]

No, look at the alphas you used at 60..... 8 vs 14.4 is a big jump down. You'd need almost 2 oz of the Cent to equal the bitterness of 1 oz of the Magnum.
Remember, it's not just the alpha but also the TIME.

[BDawg]

Ok, I just ran it through promash and you are right, it will be around 63 or so IBUs. Wow. The thing is, done the other way it would have been around 85 ibus. You should probably be glad you did it this way because the other way it will be way ut of balance (too bitter). A good IPA has roughly a 1:1 BU:GU ratio. This does, the "correct" way is more like 1.30:1 which is way out of balane.

Good luck & let us know how it ends up-

[BigNastyBrew]

Thanks.

The correct way would have been without the 2nd oz of centennials. It just so happened I had 2oz to make up for the slack.

The "planned" hop schedule was:

1oz 14.4 Magnum at 60
1oz 8 Cent at 10
1oz 11.9 Simcoe at 5
1oz 8.6 Amarillo at 0

I'll keep this one updated. I had another slight problem with this one too that I hope does not infect the batch. I put a blow-off tube from the start because of the gravity and the mash at 149°. The pressure from it popped the bung out of the airlock for who knows how long. We were at a baseball game after I brewed so there's a several hour window I'm looking at on that one.

Thanks for all the feedback, BDawg.
