How is champagne made?
There are generally three types of champagne: Blanc de Blancs, Blanc de Noirs, and Rosé. Blanc de Blancs is made entirely of white grapes, usually Chardonnay. Blanc de Noirs is made mostly of black grapes, such as Pinot Noir or Pinot Meunier, with a small amount of Chardonnay. Rosé champagne is made with a blend of red and white grapes, and gets its pink color from the skin contact during fermentation.
Firstly, the grapes are harvested, usually by hand, and brought to the winery. They are then destemmed and crushed, and the juice (called must) is collected. The must is then clarifyied through a process of racking, and the solids are removed.
After clarification, the must undergoes primary fermentation in stainless steel tanks or neutral oak barrels, during which the yeast converts the sugar into alcohol. During primary fermentation, the temperature is carefully controlled, as too much heat can kill the yeast.
After primary fermentation, the wine is racked into secondary fermentation vessels, called assemblage tanks. Here, the wine undergoes a second fermentation, during which the yeast converts the remaining sugar into carbon dioxide and alcohol. The carbon dioxide is what gives champagne its bubbles.
After the second fermentation is complete, the wine is aged on the lees. The lees are the dead yeast cells that have settled to the bottom of the tank. The wine is aged for a minimum of 15 months, during which time it undergoes a process called autolysis. During autolysis, the lees break down and release flavor compounds into the wine.
After the aging period is complete, the wine is ready to be bottled. But before it is bottled, the wine undergoes a process called cold stabilization. During cold stabilization, the wine is chilled so that any tartaric acid crystals that have formed will precipitate out.
After cold stabilization, the wine is ready to be bottled. Champagne is typically bottled under pressure, using a process called methode champenoise, or methode traditionnelle. In methode champenoise, the wine undergoing secondary fermentation is bottled with a small amount of yeast and sugar. The yeast and sugar create a small amount of carbon dioxide, which is absorbed by the wine. This absorption gives the wine its bubbles. The wine is then aged for a few more months to allow the yeast to consume the sugar, and then it is ready to be consumed.
How is titration used in the production of champagne?
While the term “titration” might bring to mind high school chemistry class for some, it’s an important concept in the world of wine and specifically, champagne. In order to understand how titration is used in the production of champagne, it’s important to first understand what champagne is.Champagne is a sparkling wine that is produced in the Champagne region of France. While the method of making sparkling wine has existed for centuries, the modern method of making champagne was invented in the early 18th century by Dom Pérignon.Champagne is made using a process called the méthode champenoise, also known as methode traditionnelle. This process includes a secondary fermentation that takes place in the bottle. This secondary fermentation is what gives champagne its bubbles.
In order to control the secondary fermentation and produce consistent results, champagne producers use a technique called tirage. Tirage is the process of adding a small amount of sugar and yeast to the finished wine. This mixture is then bottled and left to age for a period of time, typically a few years.
Once the aging process is complete, the bottles are opened and the yeast is allowed to escape, a process called dégorgement. The last step is to add a small amount of sugar syrup, called the dosage, which determines the sweetness of the final wine.
So how does titration come into play in all of this? Well, the dosage, or sugar syrup, is added to the wine after dégorgement. The amount of sugar syrup added is determined by taking a small sample of the wine and measuring the acidity. This process is called titration.
The goal is to add just enough sugar syrup to balance out the acidity. Too much sugar and the wine will be too sweet, too little and the wine will be too tart. Titration is thus a critical step in the champagne making process, and one that requires a skilled hand.
So there you have it! Titration may not be the most exciting part of the champagne making process, but it’s a crucial step in ensuring a well-balanced, delicious final product.
