"Very clear colour. The nose is very peppery and lemony, with later notes of violet and coffee and then of smoke. It is light and fresh, very slightly rough, and savoury on the palate, with the alcohol still sensible, and a constantly present mineral texture. It is a very fine product resulting from Fins Bois in calcareous soil. A discrete, secret and fine cognac," Le Rouge et le Blanc, 2001.
