100% Cabernet Franc. Les Arboises is a subsection of the limestone-dominant Brézé hill. This is Guiberteau’s top red from a renowned red terroir. The monopole parcel was planted in 1957 on a rocky, chalky site and produces super-graceful, mineral expressions of Saumur. The fruit is fully destemmed and naturally fermented in concrete before resting for 18 months in new, one-, two- and three-year-old barrels. Guiberteau used about 40% new barrels in 2020. He ages this cuvée for longer than his other reds—both in barrel and bottle—feeling this site’s more angular tannins require extra refinement.
