Group of organic compounds consisting of carbon, oxygen and hydrogen, which are produced in plants during photosynthesis by assimilation of carbon dioxide. They form the basic food and energy source for all organisms and, in plants, the scaffolding substances. Important carbohydrates are above all the various types of sugar. In the vine, the carbohydrate reserves are an important factor for growth in the annual vegetation cycle. In autumn they are stored in the woody part in the form of starch, in spring this is converted into sugar, which provides the energy for budding. During grape ripening, sugar is transported into the berries. In the grape must there are carbohydrates in the form of glucose and fructose as well as the pectins.

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
