The chemistry of wine fermentation is complex when grape juice is exposed to yeast. The yeast consumes the sugar in the juice and produces carbon dioxide and ethanol.
Fermentation:Fermentation means to boil or bubble up. It is a type of chemical process where carbohydrate molecules are broken down in the absence of oxygen by involving microorganisms to form energy. This breakdown results in the desired enhancement of the food in terms of its nutrition and ...
One of the most surprising topics in wine right now (that has everyone talking) is wild fermentation. A wild-fermented wine uses native yeasts that are found on the fruit and in the vineyard. “You can find 50,000 yeast particles on a single wine grape.” –Carlo Mondavi, Raen Winery...
Congeners are the byproducts of the fermentation process. Drinks with high amounts of congeners include: 酒类风味物是发酵过程的副产物。含有大量酒类风味物的饮料包括: · Bourbon · 波旁威士忌 · Brandy · 白兰地 · Whiskey · 威士忌 · Rum ·朗姆酒 · Red wine · 红葡萄酒 Sugary mixers and tr...
Even after the fermentation is complete, a wine continues to change as it ages. After the grapes are harvested, the process of making wine begins. This is where the winemaker has several choices which can affect the resulting style of wine. ...
the most famous province is Avellino, about 50 kilometers (30 miles) east of the Tyrhennian Sea and Napoli. Also known as Irpinia, its ancient name, this is the epicenter of wine production in the region. Other provinces include Caserta in the north, Benevento, Napoli and, to its immedi...
Under what condition will fermentation occur?FermentationFermentation refers to the process by which microorganisms such as bacteria and yeasts chemically break down substances like glucose or carbohydrates into simpler substances that can be used to create chemical energy. Fermentation differs from anaerobic...
Region. Unlike wine, which in theory is made only from grapes and yeast, sake is made in a two-step process: rice is first polished, soaked and steamed. A mold called koji is then added to the rice before yeast takes over the alcoholic fermentation. The process uses so much water that...
