Boissiere (BWA-see-air) Vermouth is an essential ingredient in countless classic cocktail recipes, recognized for its floral and herbal aromas and refined palate. Boissiere's prized original blend, infused with select botanicals such as elderflower, chamomile and coriander, was originally developed in 1857 in the Chambrey Region of France, positioned along Mont Blanc. In 1971, seeking a new home, Boissiere relocated to the other, southern side of Mont Blanc to Turin, Italy. This vermouth can claim two of the "capitals" of vermouth as it home.
