Q: What are the safest wines for someone who has a mild tannin allergy rash, swollen lips? Are there any special winegrowing or production techniques that would reduce the level of tannins in a wine? A: We referred your question to Dr. Skip to content Menu. Describing Wine Tannins During A Tasting For many oenophiles, being able to describe tannins during a wine tasting is a wonderful skill to have.
Next time that you are tasting a glass of red wine, note the following observations: Do the tannins coat your mouth immediately or slowly? Do they dominate the wine or are they matched by fruit and freshness? Are they gentle and integrated? Or are they harsh and assertive? Examples Of High And Low Tannin Wines As we mentioned earlier, how much tannin is present depends on a number of characteristics including grape varietal and the climate in which the grape was grown.
Low Tannin Wines Wines that are in high production are more commonly found to have a less abrasive and smoother texture. High Tannin Wines High tannin wines, on the other hand, are often considered as low production wines.

Tanbark is the bark of certain trees traditionally used for tanning leather. The Taste of Tannins. You do not taste tannins, you feel them. Chew on one of these things: Black Tea Leaves Walnuts Grape Seeds Do you feel the dryness in your mouth and a bitterness on your tongue? Tannins in Wine. Tannins are passed into wine from grape skins, seeds, and stems. Tannins in wine can also come from wood storing oak aging.
Tannins play an important role in red wine making. Together they form bigger phenol macromolecules. There are also components called pseudo tannins or phenolic acids like gallic acid and ellagic acid which are a type of tannic acid that does not change the taste of the wine. In nature, plant tannins are found in the form of hydrolyzable tannins phenolic compounds soluble in water. These tannins protect the trees from fungi and microorganisms like bacteria - thanks to the antioxidant properties that can precipitate protein molecule formations and enzymes from bacteria.
This prevents such microorganisms from infecting the plants. Tannins are also used to make animal hides tanning leather with oak or acacia bark and for fabric dyeing hydrolysable tannins. All types of tannins are powerful antioxidants and have a positive effect on your health.
See if consuming other highly-tannic foods and beverages like dark chocolate, green tea, or black tea causes the same effect. If yes, you can switch to white wine or lighter roses. The concentration of tannins in your wine depends on many factors like the grape variety, the climate, the vineyard location and management, and the winemaking techniques.
While the grapes ripen on the vine, the fruit starts producing tannins and anthocyanin compounds. Most of the tannins develop in the grape skin. The skin tannins are influenced by the amount of sun the grapes receive. The greater the sun exposure, the more tannins are formed in the skin. So vineyards with higher light intensity in high altitude areas produce more tannic grapes. The climate also influences the concentration of the phenolic acids in the grapes.
In cooler climates, or if the fruit is not fully ripened during harvest, grapes tend to develop harsher tannins. In warmer climates or during late harvest, the grapes will have softer tannins. Also, grapes with thicker skins like Nebbiolo and Cabernet Sauvignon produce more tannic acid, while thin-skinned grapes like Pinot Noir have a much smaller amount of skin tannins. Tannin extraction during winemaking is a process in which the winemaker stimulates the leeching of the grape tannins into the wine.
This is done in a few ways:. Tannins extend the longevity of red wine. The higher the tannin content, the higher the ageing potential of the wine. How does that work? With time tannins go through polymerization - they bind into bigger polyphenolic compound molecules, which eventually fall to the bottom of the bottle and form sediments. This process results in a smoother and silkier tannin sensation. So, aging a high tannin wine is worthwhile for many wine enthusiasts and collectors.
Some white wines age exceptionally well. However, their longevity comes from higher acidity levels rather than wine tannin content.
The ability of tannins to precipitate proteins is why you feel a dryness in your mouth after you sip on a highly tannic wine. After all, saliva is mostly made of protein.
So, when you taste the red wine, or some other tannic beverage or food, the tannin binds to the saliva protein, and you feel a dry astringency in your mouth. So, what foods pair with your favorite red wine?
