Tannins (wine) in the context of Colline Teramane Montepulciano d'Abruzzo

Montepulciano d'Abruzzo is an Italian red wine made from the Montepulciano wine grape in the Abruzzo region of east-central Italy. It should not be confused with Vino Nobile di Montepulciano, a Tuscan wine made from Sangiovese and other grapes.

Montepulciano d'Abruzzo was first classified as Denominazione di origine controllata (DOC) in 1968. The Colline Teramane subzone, established in 1995 as a DOC in the province of Teramo, was promoted to separate Denominazione di origine controllata e garantita (DOCG) status in 2003 and is now known as Colline Teramane Montepulciano d'Abruzzo.In the late 20th and early 21st century, Montepulciano d'Abruzzo earned a reputation as one of the most widely exported DOC wines in Italy.It is typically dry with soft tannins and often consumed young.

Oak is used in winemaking to vary the color, flavor, tannin profile and texture of wine. It can be introduced in the form of a barrel during the fermentation or aging periods, or as free-floating chips or staves added to wine fermented in a vessel like stainless steel. Oak barrels can impart other qualities to wine through evaporation and low level exposure to oxygen.

The aging of wine is potentially able to improve the quality of wine. This distinguishes wine from most other consumable goods. While wine is perishable and capable of deteriorating, complex chemical reactions involving a wine's sugars, acids and phenolic compounds (such as tannins) can alter the aroma, color, mouthfeel and taste of the wine in a way that may be more pleasing to the taster. The ability of a wine to age is influenced by many factors including grape variety, vintage, viticultural practices, wine region and winemaking style. The condition that the wine is kept in after bottling can also influence how well a wine ages and may require significant time and financial investment. The quality of an aged wine varies significantly bottle by bottle, depending on the conditions under which it was stored and the condition of the bottle and cork. Thus it is said that rather than good old vintages, there are good old bottles. There is a significant mystique around the aging of wine, as its chemistry was not understood for a long time, and old wines are often sold for extraordinary prices. However, the vast majority of wine is not aged, and even wine that is aged is rarely aged for long; it is estimated that 90% of wine is meant to be consumed within a year of production, and 99% of wine within 5 years.
