Originating in Italy, prosecco is a sparkling white wine that is exclusively made in the country’s Veneto region, just a short train journey north of Venice. Available in sparkling, frizzante (semi-sparkling) and tranquilo (flat) variations, prosecco's original home is thought to be the village of Prosecco in Trieste… surprise, surprise. Not all wine is created equal. While a prosecco connoisseur might suggest there are numerous differences between prosecco and sparkling wine, the two most important are location and grapes. Prosecco is made in a specific manner with the skinned glera grape in northeastern Italy, whereas sparkling wine is more general, encompassing any wine that's given bubbles – or been in the vicinity of someone with a SodaStream and more than a healthy helping of curiosity. Made from the green glera grape, prosecco is produced using what's known as the Charmat-Martinotti method, in which the pressed grape juice is fermented not once but twice, in large stainless-steel tanks. The second fermentation process is when the liqueur de tirage (that's yeast and sugar to you and us) is added to maintain the CO2 levels that give the prosecco its signature fizzy finish. What's the difference between prosecco and sparkling wine? Coeliacs and vegans, rejoice! All sparkling wines, including prosecco and champagne, are naturally gluten-free and the majority are vegan depending on filtering processes, so you can fill up your flute guilt-free.
