The company produces over 200 products, primarily whole grains ground with quartz millstones,[9] as well as baking mixes,[10] beans, seeds, nuts, dried fruits, spices, and herbs, in over 70 countries.

[13] The smog in the city influenced Bob and his wife Charlee to sell the station, and move to Mammoth Lakes, a small resort town in the mountains about 300 miles (480 km) north of Los Angeles where he opened a second filling station.

After its failure, Moore was forced to move his family into an empty rental property owned by their minister.

[14] Moore worked in the hardware department of a Sears store located in Sacramento and was a manager at a J.C. Penney auto shop in Redding.

[14] Moore's drive for healthier foods started with his father's death of a heart attack at age 49, and his wife's grandmother's healthy eating obsession.

[15] In the 1950s, he discovered a book called John Goffe's Mill by George Woodbury at a local library.

[12] Bob's Red Mill Natural Foods went into business in 1978 and began producing stone ground flours and cereals for the local area.

[23] In 1988, annual sales to area health food stores and smaller grocers were approaching $3 million when the original mill was destroyed by an arsonist's fire.

[24] The millstones were spared, as grain from the second floor fell on them in the fire, which extinguished the flames around the mills, keeping the quartz stones from shattering in the heat and preserving the gears that turned them.

[25][12] Bob continued to grow the business by working with small markets, local retail and larger wholesale customers, rather than a corporate approach.

[26] They were also one of the first flour mills to build laboratories that tested their products to certify organic and gluten-free compliance.

[12] Wagner helped the company control debt by building and repairing machinery in-house, and through the purchasing of used machinery needed for expansion from older and closed mills like Seattle-based Fisher Mills, Inc.[12] The company expanded internationally starting in 2000.

[28][16] In October 2003, the company opened its Whole Grain Store & Visitors Center, a 15,000-square-foot addition to its existing facility.

[40] For years, Bob’s Red Mill sold products over the phone, via mail order, and through its website, but the company stopped all direct to consumer operations in August 2022.

[42][45] Bob's Red Mill has been recognized for its status as an employee-owned company, winning an ESOP Marketing Award in 2018.
