"Very attractive nose with ripe blackcurrants, spiced chocolate, grilled thyme, hazelnuts and bacon. Notes of tobacco and cedar, too. Full-bodied, so refined and polished with layers of finely chiselled tannins spread evenly across the wine and beautifully integrated. Blooming fruit with spicy herbs, peppermint and violets. Very long and persistent with a steady, mineral sensation in the finish. Drink or hold"

"The 2020 Biserno is a blend of Cabernet Franc, Merlot, Cabernet Sauvignon and a small part Petit Verdot. This is an enriched and profound wine with round tones of black fruit, spice, cured tobacco and tarry smoke. Biserno is shapely and generous with a full-bodied approach that is accented by crushed stone and pencil shaving. You get a lot of intensity and texture with this opulent, cellar-worthy wine."
