Anyone that knows me knows that I LOVE champagne.  And yes there is a difference in champagne, not all are created equal.  Most people only open a bottle for a celebration and if thats you then splurge and buy the good stuff.  DO NOT buy that crappy André or Cooks stuff.  Don’t waste your money or the calories.  Throw down $30-$50 and buy a nice bottle of champagne. You don’t need to spend $100 on a good bottle of champagne or sparkling wine.
However, after saying all that I would not splurge if you are going to be making a cocktail such as a bellini.  If you like sweet use a Prosecco.  If you like a bit more dry go with a bottle of Gruet Brut.
Bellinis are the perfect drink to serve at a sip and see (you all know what that is, right?), a wedding shower, Easter brunch… Its springy and light and sweet. I like blueberries floating in mine, but you can use raspberries or put a strawberry on the edge of the glass.  
You can make a pitcher of these if you are having a large party, but the champagne kinda goes flat so I would stick to making them on an as needed basis if you can.
Here is a list of champagnes/sparkling wines that won’t break the bank:
Gruet Brut-$17
Roederer Estate Brut- $30
Moet and Chandon Imperial Brut-$30
Laurent-Perrier Brut- $35-$42
Perrier-Jouet Grand Brut- $40-$45

 

Bellinis

Makes about 8 drinks

1 Bottle Champagne, Sparkling Wine or Prosecco-chilled
1 can Kern's Peach Nectar-chilled
Blueberries, raspberries, strawberries for garnish

Use pretty champagne flutes to show off the beautiful peach color of this drink. Fill the flute about a 1/8-1/4 full of peach nectar (or about 1 Tablespoon) and fill the rest of the glass with champagne.

Garnish with a few blueberries and serve!
