In Part 1: The Art of Wine Observation , we explored how to observe the color of wine to identify its characteristics and style. Having mastered the rules of recognizing and analyzing wine color – a key factor in determining the age and style of a bottle of wine – we will now explore another crucial step.

Next, let's explore the deeper meaning of swirling (or aerating) a wine glass and learn the most precise technique to awaken and release the complex aromas hidden within the bottle. We'll learn why swirling wine is important – and how to do it correctly to fully enjoy its flavor.

Review Part 1: The Art of Wine Tasting – Part 1: The Art of Observing Wine

1. Why is it necessary to shake wine?

Gently swirling wine in the glass is an essential technique when enjoying it. This action not only demonstrates sophistication but also serves important scientific and sensory purposes:

A. Fragrance Release (Aeration)

Increased Evaporation: Wine contains volatile aromatic compounds. When you swirl the wine, this action increases the surface area of ​​contact between the wine and the air inside the glass.

Molecular release: This process allows complex aromatic molecules to escape from the liquid and rise, directly into the nose of the drinker. Without shaking, these subtle flavors would be "locked" in and difficult to fully appreciate.

B. Mild Oxidation

Softening Tannins: Swirling the wine allows a small amount of oxygen to enter. For red wine, this mild oxidation helps to soften the tannin structure (astringent taste).

Unlocking hidden flavors: This is especially important with young or closed wines, as it allows the wine to unfold more quickly, softening harsh flavors and releasing complex aromas that were previously concealed.

C. Observing the "Wine Legs"

Assessing Alcohol and Sugar Content: When shaken vigorously, a film of liquid will cling to the sides of the glass and slowly drip down, forming streaks called "wine legs" or "wine tears".

Structure suggestion: While not an absolute measure, the "foot" of a wine is a physical indicator of its alcohol content and glycerol level. A glass of wine with a slow, distinct "foot" often suggests a higher alcohol content and a fuller, more substantial structure.

In short, swirling the wine is the most important preparatory step so that the nose and palate can fully appreciate the depth, complexity, and balance that the producer intends to convey.

2. How to Shake Wine Correctly?

The technique of swirling wine is simple, but it needs to be done correctly to prevent spillage and maximize the release of its aromas.

Instructions on the Proper Steps for Shaking Wine

Step 1: Hold the Glass Correctly

Hand position: Use your thumb and index finger to firmly grip the stem or base of the glass. Absolutely do not hold the bowl of the glass , as the warmth from your hands will increase the temperature of the wine, ruining its flavor.

Purpose: Holding the glass by the stem or base helps the wine maintain its ideal serving temperature and allows you to observe the color more easily.

Step 2: Start Rotating

Creating a stable base (for beginners): Place the bottom of the glass on a flat surface (table, tray, etc.). Keep your hand firmly gripping the stem of the glass.

The swirling motion: Begin by gently rotating your wrist in a circular motion (clockwise or counterclockwise). The goal is to gently move the wine, creating a thin film that clings to the sides of the glass, rather than stirring it vigorously like coffee.

Principle: Gently shaking for about 5-10 seconds is enough to release the fragrance.

Step 3: Bring the glass to your nose and smell.

Observing the Wine Foot: Hold the glass slightly away to observe the streaks of wine clinging to the sides of the glass (wine feet).

Nosing: Bring your nose deep into the bowl of the glass and take a gentle, slow breath. This is when the complex aromas (fruit, oak, spices, etc.) are released by the swirling process, providing the most complete sensory experience.

Important Note

Fill the glass only 1/3 full: This allows the wine enough space to swirl and make maximum contact with the air without spilling.

Do not shake sparkling wine: Unless you want the sparkling wine (Champagne/Prosecco) to lose its fizz and freshness. Shaking sparkling wine is strictly forbidden.

3. Some Things to Note When Shaking Wine

To ensure the best results from shaking the wine and to avoid ruining the tasting experience, you need to keep the following points in mind:

A. For Wine Glasses

Fill the glass only 1/3 full: This is the golden rule. Overfilling will cause the wine to spill when swirled, or prevent it from having enough space to come into contact with the air and release its aromas.

Use a glass with a large bowl (mainly for red wine): The larger the bowl, the greater the surface area for air contact when swirled, allowing red wine (which usually has a strong tannin structure) to "breathe" optimally.

Ensure the glass is clean: Any stains, soap residue, or lingering scent on the glass will affect the quality of the fragrance you smell.

B. Regarding Wine Style

Do not aerate Sparkling Wine: Sparkling wines (Champagne, Prosecco, Cava) are enjoyed for their effervescence and freshness. Aerating the wine will cause the carbon dioxide ( $CO₂ ) to evaporate too quickly, making the wine lose its fizz, its characteristic freshness, and become "flat".

Gently swirl Young White Wine: Young white wines are usually already quite refreshing. You only need to swirl them gently and more quickly than with red wine to awaken the fruity aromas without raising the wine's temperature.

Shake Old/Strong Red Wines: Red wines with high tannins or those that have been aged for a long time need to be shaken a little more vigorously to soften the tannins and unlock complex flavors.

C. Suggested Serving Suggestions

Always smell after shaking: The ultimate purpose of shaking is to smell. Always compare the aroma of the wine before and after shaking to notice any distinct differences.

Hold the glass by its stem/base: Always hold the glass by its stem or base to avoid warming the wine with your hand, maintaining the ideal serving temperature.

Through Part 1 (Observation) and Part 2 (Swirl) , you have mastered the basic techniques for preparing your glass of wine. Swirling the wine is key to awakening its complex layers of aroma, softening the tannins, and helping the wine reach its best expressive state.

But how do you actually "decode" the aromas you've just released? Green apple, strawberry, vanilla, or leather—which notes are hidden in your glass?
