alpha acid percent

[dm1217]

I'm trying to calculate alpha acid units.

Czech Saaz hops alpha acid: 2-5%

Since the % varies, what # should I plug into the equation? (3.5% since it's the middle? etc.)

that's what I would do till I bought the them then I would use the correct % and then adjust the recipe to get my IBU's where I want them.

Depending on where you buy your hops, some places will say what the AA% of their current shipping batch is. Rebel Brewer does this. (look half way down the linked page)
