Estufagem Process

Originating from Portugal’s Madeira Islands, the Estufagem process uniquely ages Madeira wine through heat application. This method, encompassing traditional and modern techniques, bestows distinctive flavors and extends the wine’s shelf life, reflecting Madeira’s rich winemaking legacy and its prominent role in the global wine arena.
