Are there any web sites out there that will have calculators allowing you to get the recipe for a smaller batch. Most recipes are for 5 gallons and I want to do a barleywine and would only like to do three gallons. I will be doing extract. Might it be as simple as taking the recipe and reducing it by 2/5?? I know food network does this sort of thng with food recipes (reduce serving and they adjust the ingredients).
