The base wines for this lovely white vermouth are unsulfured, certified-organic Moscato (from Vittorio Bera e Figli) and unsulfured, certified-biodynamic Cortese (from Cascina degli Ulivi). Some of the key botanicals are wormwood, chinotto (bitter oranges picked green), gentian flowers, thyme, oregano, marjoram, basil and lemon zest. Most vermouth bianchi are made with chemical components and highly industrial processes: Vergano's are the real thing, highly expressive and pretty; his are made super-small production in Torino, so they're hard to find, too. This vermouth makes the best white negroni of all time.
