Sometimes changing one ingredient transforms an entire cocktail.  The Vesper is no exception.  I made my version of this classic 007 cocktail, which James Bond himself created, with Bianco Ambrato vermouth from Mancino Vermouth.  Full disclosure -- I did not receive any compensation, but Giancarlo Mancino generously gave me a free bottle when I met him at Tales of the Cocktail earlier this year.  I also met the U.S. distributor, so we can get it through the Internet.

3 ounces vodka
1 ounce dry gin
.5 ounces Mancino Bianco Ambrato vermouth

Combine in a shaker with ice, shake con passione as if you were with a Bond girl or Bond (depending on your preference), and strain into a chilled glass.

The Bianco Ambrato has a distinctive flavor compared to other dry vermouths.  It strikes the delicate balance of asserting itself without overpowering the entire cocktail.  Bravo!
