Hops Alpha Acid Table
Sunday, September 14th, 2008Alpha Acids from hops contribute to the bitterness in beer. During the boil alpha acids are isomerized and increase international bittering units (IBUs). This site has an IBU calculator.
Hops also contain beta acids, which contribute to aroma only. The more alpha acids the more bittering potential per ounce. For example, one ounce of Northern Brewer (8.5) is roughly equivalent of two ounces of Domestic Hallertau (3.9) in terms of bittering potential.
This chart is a general guideline only. The actual AA varies from year to year depending on the weather, harvest conditions, and storage.

Love your website. I am still finding new things. Ever thougt of putting brief descriptions next to the hops and make that page printable? I am still learning all this and making a folder for brewing. CHEERS!!

Printable hops list is a great idea.
We are currently working on descriptions for all varieties, images of the leaves and cones.
Have fun brewing!

Love the calculator. Will come in handy as I’m certainly no Math wizard.
Two hops I have used of late that you can add:
– Sorachi Ace hops from Japan
– Citra hops (current batch is 13.1% AA)

I use the IBU and ABV calculators every time I brew. They are really great!
However, since I am a European, I use the metric system. It would be great if there was a metric option.
gram instead of ounce and liter in gallon (and EBC instad of SRM)

Thanks for the nice feedback.
Yes, Metric units are something on the ‘todo’ list.

I AM LOOKING FOR A HOP CONVERSION CHART WHERE YOU CONVERT LEAF HOPS TO PELLETS IN WEIGHT
