Epoxy resins are low molecular weight pre-polymers or higher molecular weight polymers which normally contain at least two epoxide groups. The epoxide group is also sometimes referred to as a glycidyl or oxirane group.
Different grape varieties thrive in different climates, but typically do best in U.S. Department of Agriculture plant hardiness zones 5 through 9. Although highly perishable, when stored correctly, grapes can last up to six weeks after harvesting.
Water use: I acre grapes (about 2400 plants) uses 25,000-35,000 gallons a week. 6 months = 24 weeks total x 25,000 gal = 600,000 gal/per season / per acre. Vineyard acreage in Calif. has increased by 63% since 1985, from 350,000 acres to 570,000.
