Ice Wine Martini

I discovered this martini in Niagara-on-the-Lake, Ontario, Canada where it is served in a number of restaurants.  Ice wine is made from grapes left to ferment on the vine during winter.  So simple and so good.  A garnish might be 2 or 3 frozen grapes on a skewer.

4 oz. ice wine

4 oz. vodka

Mix in a cocktail shaker with plenty of crushed ice.  Shake vigorously and strain into 2 martini glasses.
