Graf Brothers

What Graf Brothers does

Graf Brothers is a privately held, vertically integrated American white oak processor founded in 2003 by Greg and Dave Graf and headquartered in South Shore, Kentucky. The company sources American white oak (Quercus alba) from a 450-mile radius across Appalachia, the Ohio Valley, and Missouri, processes over 100,000 m³ of logs annually across two on-site sawmills and three regional log yards, and sells five core offerings: forestry and sourcing services, premium quarter- and rift-sawn lumber, solid oak flooring, engineered oak flooring built on a proprietary Ply-Core (multi-ply or high-density plywood) construction, and oak staves for the wine, sherry, bourbon, whisky, and rum cooperage industries. Graf Brothers claims to be the world's largest manufacturer of Rift and Quartered lumber and flooring and, since 2023, operates the largest single-site stave mill in the United States. Revenue is generated through direct B2B sales to architects, interior designers, joiners, cooperages, distilleries, fine furniture makers, and construction professionals, with dedicated sales representatives for each product line, no public pricing, and no public revenue disclosure. The company joined France-based Charlois Group in 2024 and, in June 2025, became part of the OAKING group alongside Kelvin Cooperage, creating a vertically integrated American oak platform spanning forest to finished barrel.
