DO YOU REALLY KNOW HOW TO PRESERVE WINE & WHISKEY?

1. Wine

With Vietnam's hot and humid climate, if wine is not properly preserved, it will lose its characteristic color and flavor. Here are the golden rules of wine preservation and usage.

First, you need to distinguish two conditions: storage for wine storage for a long time, and wine storage for drinking in a short time. Long-term storage of wine is often called a cellar, it is a closed room located in a basement, under stairs or in a dark cabinet ... designed and installed to meet requirements. mandatory for temperature, humidity, light ..., ensure long-term wine storage without denaturing or damaging the alcohol.

Storing alcohol for short-term use is often referred to as a cooler, it is a glass or wall-mounted cabinet fitted with a cooling device to maintain the correct temperature depending on the type of wine, the purpose of which is to When you drink, you will have the best taste. These types of cabinets are usually located in the restaurant, bar, club or private living room area. The refrigerator is not designed under the conditions for long-term wine storage.


A. Stored in the cellar:
The following are the best conditions for storing alcohol in the cellar:

• Cellar temperature: 12 ° C to 14 ° C
• There is no annual change in temperature by more than 1.2 ° C
• 55% to 70% relative humidity, ideally 60%
• No direct UV rays
• Do not vibrate

Factors affecting quality of red alcohol:

• Temperature: Must have stability for a long time. If the temperature regularly fluctuates a few degrees up or down, your wine will spoil and possibly premature aging. This deterioration in quality is caused by contraction and expansion. As the temperature in the bottle increases, the alcohol inside will expand more than the glass creates pressure in the bottle. This pressure will attack the cork's gasket, causing a leak, causing a small amount of the wine's aroma to slowly drain through the cork. The reverse happens when the bottle is re-cooled, the air is sucked back through the cork. As a result, the good aroma of the wine is exchanged with the bad air resulting in a change in the taste of the wine.
• Humidity: When the humidity is higher than 70%, mold will develop and the label will peel off. When the humidity is below 50%, the cork dries out resulting in loss of liquid in the bottle and the alcohol can degenerate and prematurely age. This combination of temperature and relative humidity allows the wine to ripen slowly, reducing mold growth, keeping the cork from drying out, and avoiding damage to the label.
• UV rays: Direct light and ultraviolet rays will make the wine quickly degenerate and lose its taste.
• No vibration: If the alcohol is vibrated by surrounding machinery or equipment, it will speed up the chemical reaction inside the wine, leading to aging and loss of flavor.

Because of the above factors, the design and installation of the cellar should be in a low location and have a stable ambient temperature. Should be placed in the basement, ground floor or recessed wall. Avoid windows with lots of light, and stay away from heat sources such as water heaters, kitchens, furnaces, boilers ... and machines with vibrations when running.



B. Store in a refrigerator: for use in a short time

To enjoy the best wine, the most important factor is the temperature. Alcohol temperature varies with each type of alcohol. If not suitable for alcohol, temperature will affect the taste and deliciousness when drinking.

We need to differentiate between the drinking temperature and the wine storage temperature. Alcohol controls temperature as outlined above. Here we talk about the appropriate drinking temperature.

Alcohol is a complex combination of unstable substances that, when used at the wrong temperature, will unbalance the elements of its primary place: sour, sweet, and bitter. If alcohol is drunk at too hot temperatures, the wine tends to evaporate quickly, causing the wine to lose its structure and possibly resemble flavor variations, leading to overturns. This happens too often when white wine is not consumed at the right temperature (9 ° C to 13 ° C).

Conversely, when drinking alcohol at too cold temperatures, the aroma can be lost, which also affects the senses and taste. When red wine is not drunk at the right temperature (17 ° C to 20 ° C), it can lead to a more bitter taste, as the tannin content in the wine does not have enough time to flavor. If your wine bottle needs to cool quickly, simply soak the metal wine bottle with ice, water and salt to cool it quickly.

So the wine manages to use, according to each wine that co-operates the optional temperature in the range of 5 ° C to 18 ° C. The wine bottle will be placed in the cabinet or multiple small cabinets combined, and adjusted. the correct temperature for each type of temperature.


The recommended drinking temperatures for some wines are as follows:

Drinking temperature   Type of wine

Dưới 6°C                    Sweet Sparkling Wine

5 - 6.7°C                    Eiswein, Sweet Vouvray

5 - 7°C                       Crémant, non-vintage Classic Rosé, White Zinfandel

6 - 8°C                       Vintage Sparkling Wine, Muscat New World, Riesling Gewürztraminer, Loire Valley Whites 

                                  (Sancerre), Sauvignon Blanc, Alsace Riesling, Italian Whites

9 - 11°C                     Beaujolais, Nouveau French Chablis, Chardonnay, White Burgundy, Viognier, Condrieu

10 - 12°C                   Tawny Port (chilled), Full-Bodied Chardonnay

11.7 - 13°C                Côtes du Rhône

13 - 14°C                   Chianti, Sangiovese, Barbera

14 - 16°C                   Young Bordeaux, Young Cab

14 - 17°C                   Merlot, Light Zinfandel

15 - 17°C                   Tawny Port

16 - 17°C                   Red Burgundy Pinot Noir Chianti Riserva Barolo Merlot (oak-aged)

16 - 18°C                   Grand Cru Bordeaux, Mature California Cab, Mature Rhone, Zinfandel, Vintage Port 

2. Whiskey

Whiskey usually has an alcohol content of about 40% ALC - 50% ALC. Whiskey storage is not as strict as wine storage, but the cellar / cabinet must also comply with the following conditions to avoid flavor loss or spoilage:

• Space: cool, dry, not damp, moldy.
• Temperature: cool and stable continuously, usually from 15 - 25 ° C.
• Light: limit light, avoid direct sunlight.
• Always place the bottle of whiskey upright, to avoid contact with the cork will damage the cork.
• After opening the cork used, to carefully close the cork, limit opening the bottle many times, making alcohol in the bottle exposed to oxygen in the air will change the taste. In case of repeated use in small quantities, many smaller bottles should be extracted.
