Burton Wood Turnery is proud to be the UK distributor of premium oak barrels handcrafted by J.M. Gonçalves — one of the most highly certified cooperages in the world.
With nearly a century of cooperage heritage, J.M. Gonçalves barrels are trusted by winemakers, distillers, and producers who demand exceptional quality, full traceability, and consistent performance.
A COOPERAGE BUILT ON HERITAGE
The story begins almost 100 years ago with AbĂlio Gonçalves in the Trás-os-Montes region of Portugal, crafting barrels for local wine producers using traditional methods passed down through generations.
His son, José Maria Gonçalves, expanded this craft internationally in the 1960s, refining his skills in France before establishing his own workshop. Through dedication to traditional cooperage and continuous innovation, the family business grew into a state-of-the-art facility on Portugal’s east coast in 2001.
Today, J.M. Gonçalves combines old-world craftsmanship with modern precision technology to produce barrels recognised globally for their consistency and organoleptic excellence.
EXCEPTIONAL OAK SELECTION & FULL TRACEABILITY
Only carefully selected oak from ecological, sustainably managed forests is used.
Every tree trunk is personally selected by the cooperage, guaranteeing origin and quality. The entire journey — from forest to cellar — is fully traceable and certified by Bureau Veritas.
Oak is naturally seasoned outdoors for a minimum of 24 months (often up to 36 months), exposed to natural weather conditions to develop superior structural and aromatic qualities.
