Does Light Affect Wine Quality?

The short answer is that light can definitely affect wine, but we need to take a closer look at the physics and chemistry of it all to understand why and how in what is called light-strike reactions, which can impart off-odors to wine, what the French call goût de lumière.

Wine, Light & Dark Glass Bottles

Wine is sensitive to the damaging rays of light, particularly ultraviolet (UV) rays from sunlight and fluorescent lighting; that's why wine (and beer) is packaged in dark bottles-the best example is Port in those familiar, dark, opaque bottles. Wines packaged in clear glass bottles are meant for quick consumption and should be stored in carton boxes until such a time.

Light, Wine And Bottles

 All forms of radiation, including visible light ultraviolet (UV) rays and X-rays, have energy that is directly proportional to their frequencies or inversely proportional to their wavelengths-that is, high-frequency waves have short wavelengths, and vice versa. And the greater the energy, the greater the catalytic effect of chemical reactions in wine.

Why are most wine or liquor bottles made of glass?

Glass bottle is a traditional domestic beverage packaging vessel, and glass is also a kind of packaging material with historical significance. With a variety of packaging materials sprouting up in the markets, glassware still occupies a vital influence in beverage packaging, which is closely related to its packaging characteristics that other packaging materials cannot match.

According to statistics, 71% of wine utensils in the world are made of glass, and China is the country with the largest proportion of beer bottles in the world, accounting for 55% of all glass beer bottles, exceeding 50 billion bottles every year. Apart from opening glass bottles, I have not seen other packaging for wine, health-care wine, and bee wine. This can be seen from the key influence of glass bottles on wine packaging. So why are so many wine bottles made of glass?

What Message Can Be Seen from the Wine Packaging?

 Although the packaging of modern wines, regardless of their grades, is becoming more and more exquisite, we can still see some information about the quality of the wine from the details of the outer packaging of the wine bottle.

Shrinkwrap Seal

The shrink wrap is the outer seal of the bottle, which is a coat that seals the wine cork and the bottle opening. The most important shrink wrap materials on the market are plastic, aluminum foil, and wax seal. Some are even double-layered plastic and aluminum foil, or double-layer aluminum foil. Basically, when we see the aluminum foil and wax-sealed wine caps, we can infer that this wine is better than plastic wine caps at least in terms of ageing. Generally speaking, plastic wine caps are common in some entry-level wines. In France, they are table wine or regional wines. So when everyone sees the wine covered with a plastic wine cap, you can probably judge that this is a more basic wine that is suitable for drinking now and should not be kept for long. Generally, the drinking period of this kind of wine is 2-3 years. If you see more than this period, it is very likely that the wine has lost its freshness and the drinking period has passed.

Why Do Some Brands Use Wooden Wine Boxes Packaging?

 High security

Wooden wine box is reinforced in structure and enjoy merits of strong endurance, abrasion resistance, strong anti-torsion ability, and large carrying capacity, etc. Therefore, the safety of wine storage is well addressed. The wooden wine box is also very delicate in workmanship, exquisite in material selection, and looks noble and elegant, but there is no lack of fashion. As a wine packaging, it is a good choice, not only can be preserved for a long time, but also can be used as a collection. Secondly, another reason for packaging red wine in wooden boxes is that red wine encounters light, and the taste of the wine will deteriorate due to premature ripening.

Tradition in Wooden Wine Box

Wooden box packaging is a traditional packaging technology with a long history. In ancient times, the ancients used to write with brushes. The boxes used by large families to hold the brushes were made of wood. Some wooden packaging boxes that have been passed down from ancient times to the present are intact. This shows that the quality of the wooden box is very good and can be stored for a long time.

For Collection

Wooden box crafts that have been passed down from ancient times to the present have a high collection value, and their value will naturally become higher and higher when they become antiques. Using wooden wine barrels to hold wine can ensure that the taste of the wine will not volatilize, not only will it not volatilize but will also follow As time goes by, the taste of the wine becomes more mellow and delicious. Therefore, wooden wine boxes have become a good choice for wine packaging boxes

What Is Boxed Wine?

We all know well about wine comes in glass bottles. But have you ever seen or drunk Boxed wine?

What is Boxed Wine 

Boxed wine refers to wine packaged in paperboard. There two types of boxed wine packaging. One is Tetra Pak paperboard boxes like paper milk containers. The other is a more common bag-in-box, where wine is contained in a plastic bladder typically with an air-tight valve emerging from a protective corrugated fiberboard box.  

Boxed wines are not very popular, but they are cost-effective. In fact, boxed wines have many advantages. First of all, their packaging boxes can be sealed again after opening, and the cardboard packaging boxes (and the plastic bladder, if included) are lightweight and will not break even if they drop on the ground by accident. It is easier to cool down than a glass bottle when in fridges. Since the box adopts a vacuum-sealed design, if you can't finish drinking the wine inside, you can continue to seal and store it, so that the shelf life of the wine can be extended. Bottled wine will go bad within a few days after opening, while boxed wine can be stored for several weeks after opening. In addition, for consumers with a strong sense of environmental protection, boxed wine is eco-friendly, especially the tetra Pak packaging.

Cheap Packaging - Boxed Wine

What is Cask Wine? 

Cask wine is another name of boxed wine. The practice of boxed wine originated from Australia. A winemaker there patented such cheap method of wine packaging on April 20, 1965, which was called Cask Wine. Polyethylene bladders of one gallon (4.5 litres) were placed in corrugated boxes for retail sale. The original design required that the consumer cut the corner off the bladder, pour out the serving of wine and then reseal it with a special peg and was based on a product already on the market, which was a bag in a box used by mechanics to hold and transport battery acid.

Disadvantage of Boxed Wine

Some doubt that the plastics involved in boxed wine packaging may release BPA (bisphenol A) which would be bad to the drinkers' health. It's up to the consumers themselves to determine or consult the wine dealer...
