Tannins are a natural preservative in wine. Un-aged wines with high tannin content can be less palatable than wines with a lower level of tannins. Tannins can be described as leaving a dry and puckered feeling with a "furriness" in the mouth that can be compared to a stewed tea, which is also very tannic.
Baked: a wine with a high alcohol content that gives the perception of stewed or baked fruit flavors. May indicate a wine from grapes that were exposed to the heat of the sun after harvesting. [5] Balanced: a wine that incorporates all its main components—tannins, acid, sweetness, and alcohol—in a manner where no one single component stands ...
French term for racking with the purpose of removing harsh tannins from the wine in the form of grape seeds. In this process the wine is drained into a secondary vessel, allowing the cap to settle to a bottom and loosen the seeds that are trapped in the pulps. As the wine drains, a filter captures the seeds and removes them from the wine.

Wine contains natural preservatives such as tannin, sugar and alcohol, [2] and can be preserved through physical preservation methods, such as storage at an appropriate temperature. [3] However, bacterial growth is still possible, so chemical preservatives are added to most wines.
A new study from UC Davis looks at the properties of red wine that result in a headache. Here's what the study says, and what it means for a wind-down drink. Actually, Tannins Might Not Be Causing ...
Greater extraction can add to the complexity and life expectancy of the wine by developing more complex tannins that will soften over a longer period of time. With these benefits does come the risk of developing various wine faults, such as the development of acetic (or "volatile") acidity. Too much extraction can also increase the harshness of ...
In winemaking, the duration of maceration or skin contact will influence how much phenolic compounds are leached from skins into the wine. Pigmented tannins, anthocyanins, colloids, tannin-polysaccharides and tannin-proteins not only influence a wine's resulting color but also act as preservatives. During fermentation adjustment to a wine's ...
