Marc de Raison Brana brandy comes from grapes from the Brana estate, which notably produces the AOP Irouléguy wine.
Various grape varieties are used. We find Cabernet Franc, Cabernet-Sauvignon and Tannat for the reds. Gros Manseng, Petit Manseng and Petit Courbu for the whites.
Distillation is carried out separately for each grape variety. Finally, a blend completes the creation of this very fine eau de vie.
