Thomas Bramwell Welch (December 31, 1825 – December 29, 1903) was a British–American Methodist minister and dentist. He pioneered the use of pasteurization as a means of preventing the fermentation of grape juice. He persuaded local churches to adopt this non-alcoholic wine substitute for use in Holy Communion, calling it "Dr. Welch's Unfermented Wine". The company he founded is now called Welch's.
