Continuous hopping question.

[eon]

I am trying to figure out how to divide my hops up if I want to do continuous hopping. So let's say I have 10 oz. or 12 oz. or 7 oz. etc... of hops. How do I know how many ounces to add at what times?

I have read where people just throw in a few at a time but I would really like to throw in the same amount of hops over the entire boil.

Thanks!

*EDIT* Also, how do you calculate IBU when you do continuous hopping?

Integral calculus. Create a formula with discrete additions over time, then make the time graduations smaller and smaller. It's really a limit problem, and will result in an integral. Textbook integral. Just use the normal integral rules. Newton? Leibniz?

[edit] sorry, feeling a bit funny tonight. Anyway, just use beersmith. It will do the math for you. Might take a while to get all the additions you want, but it'll work.

You do realize that math is my weakest subject?!

So, I googled "Integral Calculus" and here is what I found:

[ƒ(x)g(x)] dx = ƒ(x) dxg(x) dx

And you expect this to help me?!

Unfortunately, I am running a mac so I do not have beer smith. Any chance I can beg somebody to figure this out for me? Pretty, pretty please?

Maybe try beer tools?

I'll see what happens. Thanks!

Ok, well beer tools isn't working!

So, this is much simpler. How about something like this:

No bittering hop additions. During the last 10 minutes of the boil, add 1 ounce of hops every minute for a total of 10 ounces of hops.

I've heard good things about Hop Bursting, like you describe. It's a lot of hops, but I've heard it's awesome. For continuous hopping, you can check this out- http://beercalculus.hopville.com/recipe

With this site, you can only enter hop additions in 5 minute increments, but it'll give you a pretty close idea of what you'd get.
