[5] Balanced: a wine that incorporates all its main components—tannins, acid, sweetness, and alcohol—in a manner where no one single component stands ...
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.
Pseudo-tannins are low molecular weight compounds associated with other compounds. They do not change color during the Goldbeater's skin test, unlike hydrolysable and condensed tannins, and cannot be used as tanning compounds. [4] Some examples of pseudo tannins and their sources are: [7]
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.
