A company that specializes in helping winemakers add all sorts of things to wine has just launched new calculators. They are handy for deciding how much water or sugar one might want to add. Not to mention acid additions - ( tartaric, malic and citric acid addition ) fining and oak addition - ( clarification & oak wood chips addition )

No farming needed.

It is too bad there isn't a way to track who uses the calculators, then you would know which wines to avoid.
