You could always try the hopshot from northern brewer. They have a chart that adjusts you IBU's w/ the OG of the wort. It's how the big boys get their IBU numbers.

Not the Amarillo hop shop shot, I just bought the last 25 they had!

According to the chart you would need 11 hop shots boiled 60 minutes or 9.9 if you boil them 90 minutes

Ok so I use hop shots a lot and this didn't make sense to me to I re-examined the data sheet I have, and I think there was an error in the last calculation. 11 and 9.9 are correct volumes, how ever they should be in milliliters (ml) not entire hop shots. There are 5ml in every hop shot, so instead of 11 and 9 hop shots it would be approximately 2.2 for a 60 minute boil, etc. 11 hops shots would put the beer at well over 400 IBUs (in theory). Hopes this makes more sense.

That makes more sense! lol I was thinking of how expensive those hop shots would be compared to adding a few ounces of high alpha hops lol

I know, for a little while there I was thinking man I'm barking up the wrong tree with these hop shots. Then I remembered I made a 70 IBU APA and it didn't take anywhere near 11 hop shots. So for awhile I was stumped a well.

Just read a Q&A article in the May/June 2012 issue of Zymurgy on whether it is possible for homebrewers to achieve 100 IBUs. It said it is highly improbable that you can achieve CALCULATED 100 IBUs; however, with the use of late hop additions, dry hopping, and hop extracts (none of whichs' flavors are volatilized/blown off by the boil) you can end up with a beer with hop characters that has all kinds of bitterness and can rival a commercial hop monster with 100+ IBUs.

I guess the difference is that these hop characters don't register as 'measured' or 'calculated' IBUs, but if the beer actually tastes like one that does then what the hell is the difference?

Also, fwiw, I remember reading somewhere that you can not even taste a difference in bitterness past 100 IBUs I want to say.....

Calculated IBUS, for the most part, are real IBUS. Your tongue physically cannot distinguish between 100 IBU, 110 IBU, or 3000 IBU. There's also a limit on the solubility of isomerized alpha acids, but that's not really important- a 200 IBU beer and a 100 IBU beer taste the same. As for variety of bittering hops, you absolutely boil off all of the flavor and aroma contributors, so if you're looking for the big IBUs, just grab your highest alpha hop. If you're looking for a certain "quality" of bitterness, try comparing different Alpha acid/beta acid ratios, and beta acid levels.
