Groupe Charlois-backed Oak Nation, a wine and cognac producer, completed the acquisition of Graf Brothers, producer of quarter-sawn and rift-sawn American oak. Financial terms were not disclosed. “I am very pleased to welcome the Graf brothers and their remarkable teams into the Charlois family. We share the same commitment to mastering and selecting oak. For both the Graf brothers and us, it all begins with the forest. Vertical integration, from the forest to the barrel, will ensure complete traceability and production of barrels from exceptionally high-quality staves for our group’s customers, including those of Kelvin Cooperage,” Sylvain Charlois, Charlois CEO.
