Traditional Method Sparkling Wine vs. Prosecco

Traditional Method Sparkling Wine vs. Prosecco

If you don't know me personally, then you should know that I am a huge wine nerd, particularly with bubbles. I love learning and I love educating people on all things sparkling! One subject that comes up all the time is the difference between Traditional Method (champagne style) sparkling wines and Prosecco (tank method).

The major difference between traditional method and the tank method is the vessel used for secondary fermentation. Champenoise style bubbles go through secondary fermentation in the bottle, while tank method happens guessed it...a tank. I almost always prefer traditional method bubbles to tank fermented bubbles for many reasons, however, the main difference for me is the incredibly nuanced textures and flavors that are added to the wine in the Champenoise style method. Check out all the other differences below.

 traditional method

Traditional Method Sparkling Wine

Names: Traditional Method, Méthode Champenoise, Méthode Traditionnelle, Methode Cap Classique, Metodo Classico, etc. 
Examples: Champagne, Crémant, Cava, Sekt, Franciacorta, Brut  
Pressure: 5–7 atmospheres 
Sweetness: Traditional Method sparkling wines are generally on the drier side. They range from Brut Nature (zero added sugar) to sweeter styles like Demi Sec (more on sweetness levels HERE). Most champagne houses lean towards making dry Bruts, as is the current preference of consumers.
Flavors: Richer layers, toast, brioche, nut, fruit, citrus.
  1. Grapes are hand picked and fermented in tank into a dry wine (vin clair). After primary fermentation is complete, the winemaker then blends a “cuvée” of different base wines for a final blend.
  2. Yeast and sugar are added to the cuvée to start the secondary fermentation and wines are bottled (and topped with crown caps).
  3. The secondary fermentation adds more alcohol, which creates CO2, which is trapped inside the bottle thus carbonating the wine. The yeast dies in a process called autolysis and remain in the bottle.
  4. Wines are aged on their lees (dead yeast particles) for a period of time (anywhere from 12 months to years and years) to develop texture and flavor in the wine. Most believe the longer the wine ages on its lees, the better.
  5. The wines are clarified in a process called riddling which can be done by hand or mechanically. This occurs by settling the bottle upside down and capturing the dead yeast cells in the neck of the bottle.
  6. The bottles are then disgorged, which is the removing of sediment from bottle. The bottles are placed upside down into freezing liquid which causes the yeast bits to solidify in the neck of the bottle. The crown cap is then popped off momentarily which allows the frozen chunk of lees to shoot out of the pressurized bottle.
  7. The bottles are then topped off with a dosage mixture of wine and/or wine and sugar and then bottles are corked, wired with a cage and labeled.

 tank method

Prosecco (Tank Method)

Names: Charmat Method, Metodo Italiano, Cuvée Close, Autoclave
Examples: Prosecco, Moscato, Lambrusco, Espumante 
Pressure: 2–4 atmospheres
Sweetness: Tank Method wines tend to be sweeter than wines made in the traditional method. This is due to stylistic choices by winemakers rather than any inherent difference in the production methods.
Flavors: Simple, fresh, fruity, bright, sweet.
  1. Grapes are picked and fermented in tank to create a base wine.
  2. Once primary fermentation is complete, base wines are added together and yeast and sugar are added to start the secondary fermentation in the tank.
  3. The CO2 released from the secondary fermentation causes the tank to pressurize.
  4. Wines are then filtered as they are transferred to a bottle without any aging.
  5. Each bottle is topped up with a dosage mixture of wine and sugar and then bottles are corked, wired with a cage and labeled.

  • My husband and I have taken many, many classes, seminars, on site vineyard tours., winemakers.
    Your explanation of traditional and tank process was excellent. Broken down into simpler, clear terms. I’ll use your notes, when asked same questions as we serve Bubbles○°°
    Thank you for posting.
