All Grain Full Boil?

[billf2112]

I am set up for smaller all grain batches (3 gallons), but was wondering can you top it off to 5 gallons if you beef up the OG?

I can boil a max of maybe 3.5 to 4 gallons which will put me to a finish of 3-3.5 of finished volume.

I have been messing around with Hopville's Beer Calculus. http://beercalculus.hopville.com/recipe

I have used it to convert extract and all grain recipes to partial mash.

You can input the boil volume and the final volume and then adjust the ingredients to a style or OG etc.

Beer Calculus is free. I will be getting Beersmith when I go to all grain. It gives a lot more information and has a lot more versatility.
