The sugar
Grapes carry their own sugar: no malting or cooking. The white wine is thin and acidic (Ugni Blanc above all), which is just what the still needs.
- 2
The ferment
The wine ferments to about 9% and is distilled, often on its lees, without sulphur.
- 3
The still
Twice in a copper Charentais alembic heated by a naked flame: the brouillis of about 28–30%, then the bonne chauffe. Distillation must end by 31 March after the harvest.

The wait
French oak (Limousin, Tronçais), in damp cellars for a slow, gentle reduction. VS at least 2 years, VSOP 4, XO 10.
The rules
- Grapes from the Cognac region; Ugni Blanc dominates
- Double distillation in a copper Charentais still
- Spirit no stronger than 73.7% at the second distillation (raised from 72.4% in 2023)
- VS ≥ 2 years, VSOP ≥ 4, XO ≥ 10 in oak
In the glass
Dried fruit, flowers, vanilla, with age the rancio of old cellars. Other brandies follow other rules: Armagnac often uses a column alembic, Spanish brandy a solera.
