Recipe - AG - Oatmeal Pale Ale

[nigel_c]

Brewed this a few weeks back and after proper conditioning time its really come good. Can honestly say this is one of the tastiest pale ales I've ever made.
Nice simple grist but the hop schedule is a bit of a hand full. Hops came from Yakima so super fresh which really helps in a beer like this.

Og 1.056
Fg 1.011
Efficiency 80%
IBU 63
5.9% ABV

Dry hops were added to keg hopper. Comes really good after 3-4 weeks if you can resist.

Hey Nigel. Looks like a lovely recipe!

Just wondering about the hops you add at the end of the boil. Do you add them at flameout and leave them in your kettle until you've reached your pitch temp? Presumably you then whirlpool and move to fermentor vessel?

I have the recipe entered in Beersmith and it's coming out at 113 IBUs with the hops at flameout entered as a 10 minute whirlpool.

I have a similar problem, also encountered this problem whilst trying to replicate another recipe given to me.

When I enter this recipe into beersmith with my kit the IBUs are quite out as well, mine comes up as 139.9. I did have to adjust the grain amounts slight to get the O.G of 1.056 with my equipment profile whilst keeping the same %'s for the grains.

Is this increased IBU a result of my particular equipment profile I wonder and hop utilization from there? I have just used the Hop IBU tool in the past to get the desired IBU numbers but that does quite drastically change the amounts of hops used.

Anyone else ever encounter this before and have a workaround for it?

Beersmiths post boil IBU calculations are notoriously unrealistic for most home brewers. Very hard to figure out what it will be though. One way to get around it is to save your whirpool/steep hops until you've chilled to around 80C, then stop the chiller, whirpool as long as you need to and start the chilling again. This more or less stops any additional isomerization to occur making your IBU calculation more accurate and repeatable.

[Chymist]

Yeah I typically allow the wort to chill a while before added the flameout hops and then restart the chilling. Its more just that the IBU values were off even though I entered the recipe exactly as it was entered into someone elses copy of Beersmith. Still havent really figured it out but the beer tasted great and thats all that matters!

Sorry I thought I replied before now.
If I remember right the 0 mins were added at just that.
I generally start whirlpool with 10 mins left in the boil. Some recipies I wait till below 80c but I think this one was just all added at 0. Doesn't take that long to get below 80 so most of the aroma will be locked in. Really nice beer this one. Must re Brew it done time soon.

Brewed this recipe yesterday but used Safbrew BE-256 yeast (Belgian Abbaye), Magnum for bittering, then Cascade and Centennial. Hoping for a nice hoppy pale ale with a subtle Belgian spice.

Nice. Let us know how it turns out.
