Pear wine! Ah, yes, shades of undergrad.
We made our own Krushovac in the dorms. Problem is that once you go outside grapes, fermenation is tougher. B nutrients and enzymes are key.
It will take some experimentation, a spotting round or three and walking it in. It helps to have a suitemate from Whiting whose last name ends in ovich.
Just asking, but why start with pears?
