What Happens to Wine Over Time in Glass Bottles?

Unlike other beverages, wine has a special relationship with time - the older it gets, the better it tastes!

This is because, over time, wine undergoes some changes in the glass bottle. If you are curious about these changes, let's take a look.

What is wine aging?

Wine aging includes a set of reactions that improve the taste and flavor of wine over time. It distinguishes wine from other consumer products.

How does wine change over time?

Color

The most obvious change in wine occurs in its color during the aging process. If aged too long, the color of white wine changes to gold and then brown. In red wine, orange and brick red replace violet and purple tones.

The reason for this color change is oxidation. As soon as the wine bottle is opened, the components react with the air, causing the color shift. When bottling, the wine is processed with minimal oxygen exposure to minimize oxidation.

Taste
Over time, the taste of wine becomes richer, and many changes in components contribute to this. Phenolic compounds play a vital role in the formation of the taste and flavor of wine. With reduced acidity, the astringency of the wine decreases, and the taste is mellower.

Aroma
The aroma of wine can also change significantly over time. Esters, yeasts, and alcohol are used in large quantities during the preparation of wine. During maturation and storage, yeast reactions cause fermentation, which develops delicate and pleasant aromas. In addition, terpene compounds enhance the fruity aroma of wine over time.

Other undesirable changes include nutty or aldehyde notes due to yeast and bacterial corruption. Therefore, wine bottling plays a vital role in the changes that wine undergoes.

Some wine preservation essentials?
Atmospheric pressure and composition can cause favorable and unfavorable changes in the color, aroma, and taste of wine. This is why it is important to store wine bottles in areas with low humidity.

Temperature is another factor in the maturation of wine. At high temperatures, the reactions of wine increase rapidly. Therefore, fresh, fresh, and fruity wines should be stored at cool temperatures to prevent rapid aging and quality loss.

Finally, light can also affect the aging of wine because it triggers oxidation. Dark places are suitable for storing wine.
