Papaya
The green part of the papaya just under the skin, I used it in my last batch of Welches grape juice wine. The peel from 1/2 of a papaya is suppose to equal 1 teaspoon of pectic enzyme. I have since bought a bottle of enzyme at my local brew store. http://www.drinksplanet.com/what-ca...-enzyme-when-making-homemade-wine-578877.html
