The method of pasteurizing grape juice to halt the fermentation has been attributed to a British–American physician and dentist, Thomas Bramwell Welch (1825–1903) in 1869. Welch was an adherent to the Wesleyan Methodist Connexion which strongly opposed "manufacturing, buying, selling, or using intoxicating liquors" and advocated the use of unfermented grape juice instead of wine for administering the sacrament of the Eucharist, or communion, during the church Service. A few years earlier, Welch had relocated to Vineland, New Jersey, a town started in 1861 by Philadelphia land developer Charles K. Landis (1833–1900) to create his own alcohol-free utopian society, a "Temperance Town" based on agriculture and progressive thinking. Landis declared that he was "about to build a city, and an agricultural and fruit-growing colony around it." The population reached 5,500 by 1865. Landis determined the potential in growing grapes and named the settlement "Vineland", and advertised to attract Italian grape growers to Vineland, offering 20 acres (81,000 m) of land that had to be cleared and used to grow grapes. Welch had moved to the region following his sister who was one of Vineland's earliest residents and began to produce an "unfermented wine" (grape juice) from locally grown grapes that was marketed as "Dr. Welch's Unfermented Wine". This product became "Welch's Grape Juice" in 1893 when Welch and his son Charles E. Welch (also a practicing dentist) had decided to incorporate in 1893 as the Welch's Grape Juice Company at Westfield, New York. The product was given to visitors at international exhibitions. The oldest extant structure associated with the company is Welch Factory Building No. 1, located at Westfield, and listed on the National Register of Historic Places in 1983.
