Wine is one of the most consumed beverages around the world. The process of fermentation is what is responsible for turning grape juice into an alcoholic beverage. During the fermentation process in winemaking, yeast converts grape sugars into alcohol. There’s a lot more than just

even color of some of your favorite wines. For example, some byproducts that contribute to these delicious characteristics include esters, which are aromatic compounds that contribute to citrusy or floral aromas in wine.
