It's summertime and the fizz should be well and truly flowing.

While crémant and English sparkling wine are steadily gaining popularity among those who don't have the spare cash to invest in champers, our old friend prosecco is still mighty popular.

Counterfeit fizz, however, is reportedly on the rise. So that you can rest assured that your bubbles are the real deal, it's worth knowing how to spot a fake.

And have you ever wondered what the terms "DOC" and "DOCG" refer to?

Business Insider spoke to Gian Luca Passi de Preposulo, the fashion executive husband of Jessica Chastain, who also owns his own premium prosecco brand Fiol.

Prosecco is made in certain territories in north-east Italy, using mainly "glera" grapes, although other varieties such as chardonnay and pinot grigio can also be mixed in.

told us that back in 2009, when the prosecco boom began following the financial crisis, around 20% of bottles were fake.

DOC vs. DOCG

That year a consortium of producers made efforts to regulate the industry and created two classification labels, DOC and DOCG, that could confirm a bottle's status.

DOC means

production of prosecco DOC falls within four provinces of Friuli Venezia Giulia — Gorizia, Pordenone, Trieste, and Udine — and five in Veneto — Belluno, Padua, Treviso, Venice, and Vicenza.

Spotting a fake

According to the prosecco DOC's online guidelines, there are a few markers that will help you to detect whether you have a real bottle of prosecco on your hands.

Firstly, look out for a unique alphanumeric code and data matrix on the bottle collar.

Meanwhile, on the back of the bottle the label should read "Prosecco DOC" and "Product of Italy."

Don't drink it from a regular flute

To make your experience even more authentic, it may come as a surprise that regular champagne flutes are not recommended by the prosecco experts in the know. Passi de Preposulo suggests that you enjoy prosecco in a tulip-shaped glass to make the most of the "mineralogy and bouquet."
