The original reason why we drink Welch's grape juice for communion.
It actually was made for communion. Isn't that fascinating. Check out Welch's website for yourself and see
1869 Dr. Thomas Bramwell Welch, a physician and dentist by profession, successfully pasteurizes Concord grape juice to produce an "unfermented sacramental wine" for fellow parishioners at his church in Vineland, N.J., where he is communion steward. His achievement marks the beginning of the processed fruit juice industry.
