If you are just looking for a different sparkler and not “Champagne like” here are a few suggestions as to what to look out for.
Cremant – wines made using the traditional method but from outside the Champagne region therefore cannot be called Champagne. These wines tend to be softer and creamier with smaller bubbles.
Blanc de Blanc (white from white) or Blanc de Noirs (white from black) – Exactly what it says. Sparkling wine made from white grapes – usually 100% Chardonnay or sparkling wine made from the juice of black skinned grapes – usually pinot noir. Usually made in the traditional method and usually really good.
Prosecco – Italian sparkler using the Glera grape and made using the Charmat method where a secondary fermentation takes place in a steel tank. Therefore cheaper to produce and cheaper to buy. Some of the more expensive Prosecco’s are bottle fermented.
Sekt – German sparkling wine using the Charmat method. Most is made using imported wine from Italy, Spain and France.
Cava – Made from the Macabeu, Parellada and Xarel-lo grapes using the traditional method. Vintage Cava’s available and very affordable.
New World Fizz – there are mostly good or great fizzes made in new world countries. Again, look at the label to see how it’s made and what grapes are used.
Of course there are many other sparklers out there that I haven’t mentioned. Almost every country produces a sparkling wine. They are all unique styles of fizz and depending on your budget there’s something there for you.
Remember, not all fizz is made to taste like Champagne and, more importantly, there doesn't’t need to be a special reason the drink it.
