Chaptalization is the process of adding sugar to unfermented grape must in order to increase the alcohol content after fermentation. The technique is named after its developer, the French chemist Jean-Antoine-Claude Chaptal. [1] .

2018年6月25日 · Chaptalizing is the act of adding sugar to a grape must in order to increase the alcohol content of the finished wine. Since yeast consumes sugars to produce alcohol, if you add sugar to grape juice before or during fermentation the yeast will have more sugar to convert thus yielding higher alcohol levels.

2019年10月25日 · Chaptalization (chap-tuh-lie-zay-shun) is also known as sugaring, amelioration, or enrichment, and it's named after the French chemist who invented the process, Jean-Antoine-Claude Chaptal. In order to ferment wine, you need two things: sugar and yeast.

Chaptalization and acidification are two such methods of tweaking the winemaking process to ensure a better final product. More specifically, these techniques involve adding something to the mix: whether that be sugar (chaptalization) or acid (acidification).

Chaptalization is the act of adding sugar to juice or must in order to increase alcohol content post-fermentation. It’s a process that is illegal for commercial wineries in many locations, but when making wine with certain types of grapes or country wines, it’s basically required.

2003年4月11日 · Laws regulating winemaking practices (generally) respond to the realities of viticulture within a region. So in cooler areas, such as Oregon, Bordeaux, Burgundy and Long Island, N.Y., chaptalization is perfectly legal, though there are restrictions on the quantity of sugar that may be added.

2016年4月24日 · That process—we’ll stick with calling it chaptalization—involves adding sugar to grape juice before or during fermentation. And it’s far more common than you’d think.

That’s a matter of preference and there’s nothing wrong with it. But now you can be confident that chaptalization is a legitimate option, offering yet another way to grow and improve your skills as a home winemaker.

2023年2月9日 · Chaptalization, named for Napoleon's minister of the interior, Jean-Antoine Chaptal, is the process of spiking grape must with additional sugar during the fermentation process, which allows...

As a term, chaptalization is sometimes applied to the sweetening of a finished wine as well, but today’s article addresses it only for fermenting in must. So where does Pasteur come in? It happens that Chaptal reached a valid conclusion based on what we now consider faulty science.
