How do you make champagne?

To make champagne, manufacturers to start with develop a base red wine, prior to including a mixture of yeast and sugar-- understood as the liqueur de tirage-- to it.  https://scarabnet.org/?p=354 The wine is then bottled, with the yeast and sugar setting off a 2nd fermentation procedure inside the bottle. The sediment is then eliminated through a process understood as riddling, before the bottles are topped up with a 'dosage'-- a mixture of white wine and sugar-- and sealed with a champagne cork and wire cage.

The initial step in making champagne is to produce a base red wine. To do this, producers source grapes from several of the Champagne region's numerous appellations d'origine contr�l�e (AOC). The large bulk of champagne is used a blend of three grapes: Pinot Noir, which offers the wine body and structure; Pinot Meunier, which adds fruitiness; and Chardonnay, which imparts sophistication and skill.

When the grapes have actually been harvested-- generally by hand-- they are crushed and the juice (understood as must) is extracted. The need to is then moved to stainless steel tanks, where it undergoes a main fermentation. Throughout this procedure, the yeast Aureobasidium consumes the grape sugar and produces alcohol and carbon dioxide.

After main fermentation is complete, the red wine is racked off its lees-- the dead yeast cells and other solid matter that have settled at the bottom of the tank-- and a mix of yeast and sugar (the liqueur de tirage) is contributed to it. The red wine is then bottled and the liqueur de tirage activates a second fermentation procedure inside the bottle.

This secondary fermentation takes around two weeks and during this time, the yeast cells convert the sugar into alcohol and carbon dioxide. The carbon dioxide is released from the red wine and becomes trapped in the bottle, producing the bubbles that are characteristic of champagne.

When fermentation is total, the bottles are put upside down in racks so that the sediment developed throughout fermentation settles in the neck of the bottle. The sediment is then removed through a procedure called riddling, which involves the progressive turning of the bottles so that the sediment gathers in the neck. This process takes around three weeks.

When the sediment has actually been eliminated, the bottles are topped up with a 'dosage'-- a mix of red wine and sugar-- and sealed with a champagne cork and wire cage. The amount of sugar included to the white wine at this stage identifies the sweet taste of the last champagne.

Lastly, the champagne is delegated age for a minimum of 15 months. Throughout this time, the white wine undergoes a procedure called autolysis, throughout which the yeast cells break down and release flavour compounds into the red wine. As soon as the champagne has actually been aged for the minimum period, it is all set for sale.
