This is NOT a political discussion, so all the trolls get the hell out.
Obama's WH Honey Porter Recipe calls for "10 HBUs bittering hops". How many IBU's is 10 HBU's?

I believe it was probably a misprint but could be wrong.

HBU is a Papazian thing = Home Bitterness Units.

It's %AA x Ounces. E.g., 5% AA x 2oz = 10 HBU

You'd need the boil time to figure out the IBU

HBU is "Homebrew bittering units". Multiply AA% by amount ex: 2 oz of 5% AA = 10 HBU.

Here is what i have found.
HBU ( Home Bittering Units)

For a Five Gallon Batch- Multiply the ounces of hops used for Bittering by there Alpha Acid Number. For Example: 2 ounces of Kent Golding Hops at 5% apha acid per ounce equals 10 HBU or 2oz. times 5 %(AAU) = 10 HBU

IBU ( International Bittering Units) To calculate Total IBU's from per gallon AAU's, first determine the approximate efficiency of hops isomerization. Hops boiled for 50 to 60 minuted will have 30% of the alpha acid converted. Hops boiled for 30 minutes will have 21% of the alpha acid converted. Hops boiled for 5 minutes will have 10% of the alpha acid converted.

also there is a calculator herehttp://www.djmphotography.com/www/Br...lets/Hops.html

An hbu or homebrewer unit is the weight of the hop addition multiplied by the alpha acid
