For nearly 20 years, oak alternative products have accompanied wine aging across the globe. Today, Groupe Barthe launches DUO, a range designed with the same high standards as our barrels and driven by the expertise of our three cooperages. Our ambition: to offer each of our winemaker partners a solution adapted to their needs.

Rigorous Oak Selection Our wood comes from high-forest timber, carefully seasoned for 18 to 30 months in the open air. Both the selection of our wood and its maturation reveal the full aromatic richness of the oak, depending on the type of format from our range. Each lot is identified and traceable.

Precision Toasting The strength of DUO lies in the diversity of products offered: 4 distinct products and over 15 total toasting modalities—a unique aromatic palette.

A Complete and Flexible Range Cubes, blocks, staves, or barrel inserts: DUO offers solutions adapted to all winemaking styles and every aging objective.

Note To guarantee full efficacy, our products must be stored in appropriate conditions. Their use must always comply with the regulations in force in each country and production zone.
