Sugar's role in dictating the final alcohol content of the wine (and such its resulting body and "mouth-feel") sometimes encourages winemakers to add sugar (usually sucrose) during winemaking in a process known as chaptalization solely in order to boost the alcohol content – chaptalization does not increase the sweetness of a wine. [1]
The subjective sweetness of a wine is determined by the interaction of several factors, including the amount of sugar in the wine, but also the relative levels of alcohol, acids, and tannins. Sugars and alcohol enhance a wine's sweetness, while acids cause sourness and bitter tannins cause bitterness. These principles are outlined in the 1987 ...
Sugar alcohols (also called polyhydric alcohols, polyalcohols, alditols or glycitols) are organic compounds, typically derived from sugars, containing one hydroxyl group (−OH) attached to each carbon atom. They are white, water-soluble solids that can occur naturally or be produced industrially by hydrogenating sugars.
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
The alcohol by volume shown on a bottle of absinthe. Alcohol by volume (abbreviated as alc/vol or ABV) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage, expressed as a volume percent. [1][2][3] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 ...
Port wine is typically richer, sweeter, heavier, and higher in alcohol content than unfortified wines. This is caused by the addition of distilled grape spirits that fortify the wine, but also halt fermentation before all the sugar is converted to alcohol, and results in a wine that is usually 19% to 20% alcohol.
The Oechsle scale is a hydrometer scale measuring the density of grape must, [1] which is an indication of grape ripeness and sugar content used in wine-making. It is named for Ferdinand Oechsle (1774–1852) and it is widely used in the German, Swiss and Luxembourgish wine-making industries. On the Oechsle scale, one degree Oechsle (°Oe ...
The alcohol content of a wine contributes to its body. Extract Everything in a wine except for water, sugar, alcohol, and acidity, the term refers to the solid compounds such as tannins. High levels of extract results in more colour and body, which may be increased by prolonging the wine's contact with the skins during cuvaison. [2] [3] Extra dry
