Sparkling wine might just be the most technical of all wines in the world–even if it is so easy to drink! The reason most sparkling wine is so complex is because of the need for two fermentations; one to make wine and the other to make bubbles. Since sparkling wines were first introduced (starting in the mid 1500’s), several processes have been developed and each result in a unique sub-style of sparkling wine. Take a look at the major sparkling wine production methods and which wines are made with each technique. How Sparkling Wine is Made There are 6 major methods by which sparkling wines are produced, each resulting in a different carbonation level and, ultimately, a different style of bubbly! We’ll discuss all the styles, but the two worth paying attention to the most are Traditional Method (used for Champagne, etc) and Tank Method (used for Prosecco, etc).
