How to Make It
In a bowl, toss the strawberries with the sugar and let stand, stirring occasionally, until the strawberries release their juices, about 10 minutes.
In a blender, combine half each of the strawberries and their juices, the vodka and lime juice with 1 cup of ice and puree. Pour into a pitcher. Repeat with the remaining strawberries and juices, vodka and lime juice and 1 more cup of ice. Fill 10 collins glasses halfway with ice. Pour the cocktail into the glasses, top each with about 1/2 tablespoon of Riesling and serve.
