I was wondering which method is the most accepted for calculation IBUs. Is it Tinseth?

I am having trouble calibrating what I think...say 60 IBUs is to what it really is. I have made my software default to a method which inevitably calculates the IBUs to much greater than Tinseth. Basically, what is the standard for most commercial breweries?

Okay...so I have tried 4 different methods. Using Papazian's basic arithmetic I got 44.3 IBUs, my software 38.3, Tastybrew recipe calculator: around 50, tastybrew bitterness calculator: 28.34

So, basically I know my bitterness should be somewhere between 28 and 50 IBUs. A little bit too large of a range for me!

Just pick one and stay with it. You'll soon learn what you like. I use Tinseth in Promash.

Who can really say at what level YOU detect bitterness.

Yeah...you're right. I get a little too mixed up in what I think my beer should be as far as standards are concerned. I have been using the same calculator for all of my most recent beers. I will just stick with it and manipulate the hops to what I like. My ESB had a bitterness of 38 IBUs but it didn't taste as hoppy as I thought it should. The more I think about it, 38 is actually kind of low. I guess I should just add more hops next time...

I was just wondering if there was any standard. After looking into it, two places say they use the same method yet there outcomes are completely different.

Just out of curiousity...

An extact ESB with an OG of 1.049...only a 2 gallon boil

1 oz Northern Brewer (7.8%) 60 min
1 oz Perle (8.2%) 30 min
1 oz Willamette (4.5%) 10 min

What would you change? It came out really good just not quite bitter enough in my opinion. I think next time I will add another 1/2 oz of bittering hops

When I look at a recipe, there's generally a range for IBU's. I always go for the upper end and maybe a little higher.

I understand where you're coming from. I always hate it when there is more than one standard to choose from

I plugged that in to the TB calculator, and it gives more bitterness will a 6-gal boil volume.
Personally, I would add the Willamette at 5 mins, & the Perle at 15. Build up the No. Brewer for increased bitterness. Another half oz ought to do it. If not, boil them for 70 minutes rather than 60.

if you have the ability, do the same recipe but with a full boil. hop utilization goes down as boil gravity goes up...therefore you will always get less bitterness out of a partial boil due to its higher concentration...

Tinseth is the way to go....

Remember that Commercial Breweries are doing way bigger batches than we typically do.
I use Tinseth and my beers are better since I switched.

Unfortunately, I don't have the ability to do a full volume boil yet. Still stuck on the stove top with a smaller brew kettle. I realize that the bigger the boil, the more hop utilization but that isn't feasible yet...

Maybe I will make the switch to Tinseth. I checked this morning and I think I have been using Rager which is completely different when compared to Tinseth.

My IBUs went down from 38 to 22 I think when switching to Tinseth
