2 large sprigs fresh mint, plus 6 smaller sprigs for garnish
2 ½ pints mixed fresh berries, such as red or golden raspberries, blueberries, tiny strawberries, blackberries, pitted Bing or Queen Anne cherries
2 cups chilled Champagne, or other sparkling white wine
Combine honey, lime juice and large mint sprigs in a small saucepan; warm over low heat just until the honey melts. Remove from the heat and let steep for 5 minutes; discard the mint.
Place the fruit in a large bowl, pour the honey mixture over and stir gently to combine. Divide the berry mixture among 6 individual goblets or dessert dishes and refrigerate until ready to serve, up to 1 hour.
Just before serving, pour the Champagne (or other sparkling wine) over the fruit. Garnish each serving with a sprig of mint and serve.
