Pinot gris, pinot grigio (US: / ˈ p iː n oʊ ˈ ɡ r iː dʒ i oʊ,-dʒ oʊ /, UK: / ˈ ɡ r ɪ dʒ i oʊ /), or Grauburgunder is a white wine grape variety of the species Vitis vinifera.Thought to be a mutant clone of the pinot noir variety, it normally has a pinkish-gray hue, accounting for its name, but the colors can vary from blue-gray to pinkish-brown.
[5] If the fermentation is not complete, the wine will contain residual sugar content. The sugar acts as nutrient needed for the growth of bacteria, which can deteriorate the wine or even turn it into grape vinegar. [5] Because the alcohol content of wine is relatively low, the alcohol cannot completely inhibit the proliferation of bacteria.
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
Wine is a fermented beverage most commonly produced from grapes. Wine involves a longer fermentation process than beer and often a long aging process (months or years), resulting in an alcohol content of 9%–16% ABV. Sparkling wines such as French Champagne, Catalan Cava and Italian Prosecco are also made from grapes, with a secondary ...
Wine is an alcoholic drink made from fermented fruit. Yeast consumes the sugar in the fruit and converts it to ethanol and carbon dioxide, releasing heat in the process. Wine is most often made from grapes, and the term "wine" generally refers to grape wine when used without any qualification.
The addition of additional ethanol kills yeast, leaving a wine that is high in sugar and alcohol content. [3] Fruit wine – Fruit wine is a fermented alcoholic beverage made from a variety of base ingredients and can be made from virtually any plant matter that can be fermented. The fruits used in winemaking are fermented using yeast and aged ...
It is possible to produce white (colorless) wines from red grapes by the fastidious pressing of uncrushed fruit. This minimizes contact between grape juice and skins (as in the making of Blanc de noirs sparkling wine, which is derived from Pinot noir, a red vinifera grape). An alternative method to maceration is hot press or thermovinification ...
Esters: [2] Ethyl acetate is the most common ester in wine, being the product of the most common volatile organic acid — acetic acid, and the ethyl alcohol generated during the fermentation. Norisoprenoids , such as C13-norisoprenoids found in grape ( Vitis vinifera ) [ 8 ] or wine , [ 9 ] can be produced by fungal peroxidases [ 10 ] or ...
