Altbier Grain Bill Calculation Question

[DawgBrewer]

Does anyone know of a good/free online homebrewing calculator that I can plug in the percentage of each grain in my bill to calculate for a 5 or 6 gallon batch?

I'm trying to use Kaiser's Altbier recipe for a 5 or 6 gallon batch with a boil volume of 7.9 gal to finish with 6 gallons. Any insight would be greatly appreciated.

Hopville.com's BeerCalculus is free and pretty decent IMO. Beersmith has a free 30day trial you can use as well.

Youll want to go to the "recipe builder" page.

Its a bit simpler than some (no water calcs since my water quality yeilds good efficiency and great beer so I don't bother) but has everthing I use for brewing.
