It would be entirely fair to say that the Gers department in south-west France is not one of the country’s most celebrated wine regions,  but the Saint-Mont appellation is producing some remarkable whites from local grapes such as Petit Courbu and Petit and Gros Manseng. This delicious, judiciously aged blend is every bit as good as more expensive white Bordeaux, with lots of zip and acidity, flavours of pink grapefruit, quince and white peach and a touch of oak spice.
