The Trousseau grape originates from the Jura region in the mountains of eastern France. While Trousseau may call France its original home, it’s Portugal where the dark-skinned grape has become most beloved. Known locally as Bastardo, the grape is traditionally used in the production of port wine. But on the Madeira Islands right off the coast of Portugal, it is occasionally used to make Madeira Bastardo wine. We sourced Madeira barrels right from the islands for aging this Barleywine-style Ale.
