Wine Maker Notes
Vermouth is an aromatized wine~ made from a neutral~ dry white basic wine which is then blended with an infusion. The infusion~ which gives each vermouth its unique and distinctive character~ is created by flavoring the basic wine with a special selection of herbs~ flowers~ fruit peels~ seeds~ plants and other botanicals. The addition of brandy fortifies the vermouth to 18% alcohol by volume. The prized and closely guarded recipe is used to make Boissiere has not changed since 1854.
Tiny bubbles elevate an attractive bouquet of ginger and brown spice. Appealing baked apple, honey and cinnamon flavors meld seamlessly with nutty caramel flavors gained from extended sur lees aging. The creamy and seamless structure combined with balanced acidity carries these flavors through the lingering finish.
