“Texas is now the place where you can make money.”
So wrote ambitious, 24-year-old millwright Charles Hilmar Guenther to his parents back in Germany in 1851 after he emigrated to America three years earlier. He found living in early Texas not to be as pleasant as living in Germany, but his determination and knowhow launched a company that today ranks as one of the world’s largest purveyors of food products, including the iconic Pioneer and White Wings flour brands.
Guenther’s decision to practice his trade in Texas stemmed from a shortage of millers in the state. He set up his first water-powered mill to grind grain into flour at the juncture of Live Oak Creek and the Pedernales River just outside Fredericksburg. But a drought in 1856 stunted growth of grain crops and reduced the flow of water necessary to power the mill.
Declaring that “with me, milling is the main thing,” Guenther moved farther south to San Antonio, where “only one meager water mill” existed. His new mill on the swifter-flowing San Antonio River a mile south of downtown opened in 1860 and filled what he called “a real need for a good mill.”
It was Guenther’s entrepreneurial spirit that led to creation of the oldest family-owned business in Texas and one of the oldest continuously-operated, family-owned milling companies in the U. S. True to the name of his brand, Guenther not only pioneered as a Texas miller but soon flourished as a successful Texas businessman.

His company, C. H. Guenther & Son, began with the production of flour and grew to offer a vast array of food products, says Svetlana Markova, senior brand manager.
“Today Pioneer competes with global brands in various categories,” she explains. “It’s the number 2 branded gravy in the country and the number 1 white gravy platform consisting of country, sausage, peppered, biscuit and smoky bacon gravies. Other very popular gravies include brown and roasted turkey, and there are a variety of seasonings and easy-to-make baking and pancake mixes. White Wings is well-known for its flour and tortilla mixes that have been enjoyed by generations.”

In Markova’s view, what sets Pioneer and White Wings apart is product quality that hasn’t changed over the years.
“This is something we take very seriously,” she says. “Family members from different generations often say to us that ‘this is the taste I remember when my mother or grandmother made it.’ Such feedback speaks to the commitment the company has made to product quality and positive consumer experience year after year.”
What began in Fredericksburg and San Antonio now touches other Texas locales. C. H. Guenther & Son employs 700 Texans in five plants – San Antonio (dry mixes, wheat and corn milling); Bryan (fresh buns and muffins); Dallas (frozen dough); Duncanville (frozen dough); and Denton (dry mixes, wheat and corn milling).
Texas farms also grow some of the grain the company requires for its products. “We’re not exclusively Texas-supplied because the weather doesn’t permit Texas to meet all our needs,” says James Schick, vice president of purchasing, “but about one-third of our supply comes from Uvalde and Medina.”
Grain from Texas and elsewhere arrives at a San Antonio landmark that once held the distinction of being the city’s tallest structure – a square, castle-like, 20-story grain elevator made of concrete and emblazoned with Pioneer and White Wings in huge lettering. It opened in 1922 as part of a major mill expansion, and it continues to function in the production process. It also stands as a highly visible and convenient icon that both day and night helps wayward motorists and pedestrians regain their bearings.
Upon arrival at the elevator, grain goes to various bins in the tower for cleaning, blending and eventual transfer to the milling unit for grinding into flour and packaging for distribution.
Down below at ground level, visitors enjoy breakfast or lunch at The Guenther House restaurant, many of them oblivious to the manufacturing process taking place next door. The stately, two-story structure that now houses the restaurant was built in 1860 as a spacious dwelling for the growing Guenther family. The builders used local materials including limestone quarried from a site that ultimately became the city’s Brackenridge Park on the San Antonio River north of downtown. Mortar used to cement the stone blocks contained sand mixed with horsehair.
Guenther’s youngest son, Erhard, became president of Pioneer Flour Mills in 1902 and undertook a major remodeling of the family home that made The Guenther House appear much as it does today. In addition to the restaurant, the former family homestead now includes a museum, originally the library, as well as The San Antonio River Mill Store and The Roof Garden.
