My Irish Red recipe (first AG) based on Jamil Zainasheff recipe. I've calculated using the tastybrew.com recipator in the past with no problems. But this time it seems SCREWED-UP!!! There's no way .33 oz. of 4.5 AAU hops is providing 43 IBU's! Is there? Recipe is below (yes I know the gravity is low, I wanted a session brew for FB season)

Stats
OG 1.040
FG 1.012
IBU 43
ABV 3.6 %
SRM 22

Boil Volume 5 gallons
Batch Size 5.33 gallons

3.0 % 0.25 British Roasted Barley 0.9 27.0
4.5 % 0.38 American Crystal 60L 1.6 4.2

Yeast S-04 Apparent Attenuation 69%

Brewhouse efficiency -68% (based on previous partial mash #'s)

What's up with my IBU's???

Schlante,
Phillip

You are correct. That would be about 6 IBU's. I would think you should want to use a reliable program for brewing like Beersmith as it has been considered a good choice by a large number of brewers.

I use tastybrew. If you make a mistake putting in grain "use"(extract, steep, mash) then your numbers will be messed up. I did that once and had a hard figuring out the what was wrong. Look at your grain "use". Charlie

If you suspect something is way off it usually is something that was screwed up when the data was entered into the program. If you use another program then it will agree or show the error to be true. Every one of these programs use slightly different formulas and so they will never agree right on the money but very close if the formulas are done correctly. We being the end users are at the mercy of the programmers. That's why we all tend to agree when a given program gives consistantly good results. The programmer got it right.

My problem more properly stated would have been this:

When my batch size is 5.33 gals. the IBU's are 43, but when my batch size is 5 gals. the IBU's are 8. Thus my conclussion is the computations were correct at 5 gals. so I'll go back and redo the #'s... I'll keep y'all posted. Hope my conclussion isn't wrong... but like I said, the www.tastybrew.com recipator has always worked like a charm in the past! Not sure why the added batch volume would make such a huge difference.

I've forgotten which bier formulation software is created for the Mac?

Thanks and Schlante,
Phillip

Well for what ever crazy reason tastybrew calculator screws up royal like when you change the batch size from 5 to 5.33! It seems to calculate fine at the 5 gal batch size. Thanks for the replies guys. Also I'm not using chocolate, that should be Crystal 120.

Thanks again!
Phillip

Fyi the 5 gal batch size shows an ibu of 19 for 1 oz Kent Goldings, more like it! But when the batch size is changed to 5.33, I get a whopping 140 IBUs!!!! Guess that extra .33 gals makes a big difference

Seems to have gone flaky on me also, adding 1oz NZ Hallertau 7.1 %AAU at 40 minutes and 10 minutes gave some crazy number like 120 IBU's. Seems some little bug has been introduced into the code, in short if it does not look right, it's not. At least when it is off it is way off.

I use BeerAlchemy and have been very happy with it.

I believe they have a 15 or 30 day trial that you can download.
