How is Champagne/Sparkling Wine Made vs Wine

For both champagne and sparkling wine, the most popular grapes are Pinot Noir, Chardonnay,
and Pinot Meunie. The difference between champagne and wine is the second fermentation
process. Champagne, or any sparkling wine, contains tiny fizzy bubbles of carbon dioxide,
while a standard, still wine is a fermented grape juice without the characteristic bubbles. To be
called champagne instead of sparkling wine, the wine must be made in France's Champagne
region. You can read more about the difference between champagne and sparkling wine here.

How it is Made Step By Step


Grape Harvest
In the Champagne region, grapes are picked between August and October. The grapes must be
harvested by hand when they are perfectly ripe to ensure the balance between sugar and acidity
is just right.
Pressing
Entire bunches of grapes are generally pressed together to obtain an uncoloured must from the
grapes. For the finest champagnes, each grape variety will be pressed separately.
First Fermentation
The clear grape must is transferred to stainless steel tanks or wooden barrels. About 24 hours
after the grapes have been pressed, natural yeasts are added to start the first fermentation
process. It takes around 8 to 10 days for the sugars to be completely converted into alcohol to
produce a still, dry white wine with a high acid base.
Blending
This is where the true magic starts to happen. Master vintners will taste and select the perfect
blend of wines to create a range of champagnes to best present the year’s harvest.
Tirage or Second Fermentation
During the second fermentation, all of the sugar is converted into alcohol. Bottles are stored
horizontally at high humidity and a constant temperature of 10-12°C. This slow, natural
yeastdriven chemical reaction produces carbon dioxide that gives the wine its bubbling
effervescence.
Aging on the Lees
The magic of the champagne method lies in the slow aging period. As part of the second
fermentation process, spent yeast cells, called lees, are produced. The wine will age on the lees
for some time before they are removed from the bottle. The best sparkling wines and
champagnes will age for a minimum of 15 months or several years.
Riddling
Remuage or riddling is the process where the natural sediment is removed from the champagne
bottle. The bottles are racked and, over the course of several days, their position is slowed
altered from horizontal to almost vertical with the capped neck facing down. Gravity forces the
spent yeast particles and sediment towards the neck.
Disgorging
In the process of dégorgement or disgorging, the crown cap needs to be removed to expel the
sediment without losing precious champagne or its distinctive effervescence. The neck of the
bottle is dipped in a freezing brine solution at minus 26°C and then turned upright and briefly
uncapped.
Corking
With the bottle topped up, the wine bottle is corked and wired to ensure the high internal
pressure needed to allow the carbon dioxide to create the beautiful champagne bubbles. The
final bottle of sparkling champagne will be allowed to rest for a further few months, or even
years, to allow the final flavour to combine to perfection
