<\/p>\n\n In wine, tannins are part of the so-called “structure” of taste. It is because of them, the wine seems dry.\n <\/p>\n
\nTannin is a polyphenol of natural origin, found in plants, seeds, bark, wood, leaves, and peel of the fruit. In the leaves of plants they constitute up to 50% dry matter.\n<\/p>\n
\nWine tannins are found mainly in red wines. In white they can appear as a result of aging in barrels.\n<\/p>\n
\nOn the palate the wine tannins give a bitter and astringent sensation of astringency. Strong black tea without sugar is almost pure taste of tannin, dissolved in water.<\/p>\n
\nAt the same time, tannins give red wine its complexity.\n<\/p>\n
\nThey felt basically the middle part of the tongue and the front part of the mouth.\n<\/p>\n
\nTwo possible sources of tannins in wine is grapes and wood (barrels).\n<\/p>\n
<\/p>\n
\nGrape tannins are present in the skin of berries, seeds, combs (“tassels”, for which the berries cling to the branch).\n<\/p>\n
\nThis is why red wines tannins much more: in the process of making the wort for a long time in contact with skins of berries (and sometimes with ridges), and the tannins have time to dissolve in water and alcohol. (see maceration)\n<\/p>\n
\nSome varieties and types of wines are more tannic than others (for example, Nebbiolo, used to make the famous Italian Barolo is vysokotochnye grade).\n<\/p>\n
Other examples:<\/p>\n
\n Tannins from the barrel pass into the wine as a result of direct contact with the wood during fermentation and aging. As a rule, oak barrels, because they bring in the wine interesting flavors (e.g., vanilla).\n <\/p>\n
\nBut it may not be a whole barrel. Increasingly, the wine used oak chips, boards from the barrels and other wood materials and even tannin powder since it is much cheaper. The whole barrel can be used in the manufacture of wine up to 70 years.\n <\/p>\n
Health \u2013 good\n <\/p>\n
\nThere are studies on the influence of wine and tea tannin on oxidative processes in the body. Tests have shown that tannins prevent the wine to them, and tea \u2013 no. Ie wine tannins \u2013 this is very useful.\n <\/p>\n
\nAnd the head they are not sick? There is no conclusive evidence linking tannins with a headache (migraine). In General, to eliminate tannins from your diet, you will have to abandon such foods high in their content, like chocolate, nuts, fresh Apple juice, tea, pomegranate and, of course, wine.\n <\/p>\n
\nFor the development of wine \u2013 well <\/p>\n
\nRed wines capable of long aging, the tannins were a key element of this ability.<\/p>\n","protected":false},"excerpt":{"rendered":"
