Whether it's for a birthday, Christmas or other special occasions, people often toast with a sparkling bottle of sparkling wine! But the world of sparkling wine is very diverse and can seem confusing. So we'll shed some light on the matter:
Sparkling wine is a general term that includes all wines that contain carbon dioxide. These primarily include sparkling wine, prosecco and champagne. Just like “still wines”, sparkling wines come in all varieties: from sweet to dry, from light to heavy and in red, white and rosé.
The basis for all sparkling wines is always a still wine. This is then carbonated. This is achieved by adding sugar and yeast to a finished light wine. The yeast then ferments the sugar into alcohol. As with the first fermentation, the gas CO₂ is produced. This gas is then retained, which creates pressure in the container, under which the gas dissolves in the liquid as carbon dioxide. The longer the yeast is stored in the wine, the more additional typical aromas of the sparkling wine are formed and the bubbles become "finer". In other words: the glass sparkles even more!
In the case of sparkling wine, the fermented base wine is usually light because alcohol is added to the wine during the second fermentation.
