Acid is widely used as a preservative. In red wine, Sulfurous anhydride or sulfur dioxide (SO2), in particular, is the most frequently used source. [4] Acid protects wine from bacteria by regulating the pH value, which affects the growth and vitality of yeast during fermentation. [2] Acidity also directly affects color, balance and taste. [2]
The grape debate has been settled. Two scientists at the University of California, Davis, believe they discovered why cabernets, pinot noirs and other types of red wine cause such brutal hangovers ...
The pineapple [2] [3] (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae. [4] The pineapple is indigenous to South America, where it has been cultivated for many centuries.
Malic and tartaric acid are the primary acids in wine grapes. The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria.
280 nm 45 min LC chromatogram of a red wine, showing mainly phenolic compounds. Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity ...
Researchers may be closer to knowing why red wine causes headaches for some people, according to a new study.
Red wine spills may be inevitable, but red wine stains aren’t. So don’t panic. Here’s what you need to know to get red wine stains out of everything from your clothes to your countertops.
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
