It's sad to see how many websites perpetuate myths about wine storage just to convince consumers that only the most expensive wine coolers/cellars/fridges can prevent fine wines from turning to vinegar overnight. Unfortunately, the truth is far less motivating. Below we discuss the basics of typical wine storage - i.e., wine held for personal consumption rather than speculation - and to help clear up some of the rampant confusion so new enthusiasts can make sensible, cost-effective buying decisions.
Terminology - Wine Coolers, Fridges, Cellars, Etc.
Wine Cooler vs. Wine Cellar - What's the Difference? We see lots of blogs and other websites that attempt to define and separately categorize wine coolers, wine cellars, and wine refrigerators

And because corks are porous, this essentially causes the bottle to "exhale" through the cork when temperatures push upwards and "inhale" as they come back down. In other words, some gas from the ullage is pushed out and fresh air is pulled back into the bottle during significant temperature swings. This fresh air, unlike the original gas composition of the ullage, has a fresh supply of oxygen - and more oxygen means higher rates of oxidation. As a result, a continuous cycle of excessive "breathing" can quickly degrade wine by over-maturation just as surely as continuous storage in elevated temperatures can. Again, you don't need to panic over a swing of a few degrees; however, the more stable you can keep your wines around the set temperature, the better. Try keeping your wine cooler full - a larger volume of wine in the cabinet results in greater thermal inertia, which helps minimize temperature swings due to fluctuating external …show more content…
Tannins, which are present in virtually all wines, are a class of very powerful phenolic compounds, and these compounds help to reduce the effect of "light struck flavor" in UV-exposed wine. Tannins are present in the highest concentrations in dark-colored grape skins. White wine, made with light-skinned grapes, has much less tannin, and therefore has less much less protection from a similar period of UV exposure than a red wine. This is analogous to the greater risk of sunburn light-skinned people face due to their relative lack of UV-protecting melanin.
Now the good news is that wines stored in opaque or amber-colored bottles are very well-protected from UV light, as compared to green bottles, or the worst - clear bottles, which offer little to no UV protection. In addition, most wine coolers/cellars today use UV-free LED interior lighting and tinted door glass that further minimizes the risk of UV degradation. So, assuming you don't buy wine in green or clear bottles, and are storing your collection in a dim location or within a typical wine cooler, you have nothing to worry about.

An Investigation Into How the Thickness of Insulation Affects the Time a Drink Takes to Cool Down
The Roman writer and naturalist Pliny the Elder, in his treatise Naturalis Historia states “there is nothing more useful than wine for strengthening the body, while, at the same time, there is nothing more pernicious as a luxury, if we are not on our guard against excess.” Years before he wrote those words, wine had in fact come from humble origins outside Italy itself. Furthermore, the process of fermenting grapes goes back thousands of years, and its beginning can be traced to where the wild grown grape-vine, vitis vinifera, flourished and was actively utilized for this reason.
In the span of only a few pages, L.B. Church has given us an overview of the winemaking process. He has done so with sufficient detail for those in the chemistry community to follow along, yet still in a cursory enough manner as to not bog them down with the unnecessary. Written as if it were the procedure of an experiment, he has given enough information for the experiment to be repeated, tested, validated and improved upon. And that is almost assuredly his goal from the very beginning, as it must be for any published author in the chemistry community.
When people are exposed to UV light, from the sun or, for example, in a tanning booth, the melanocyte cells make more melanin and pack together tighter, resulting in darker skin tones. If the skin is receiving too much ultraviolet light, the melanocytes may begin to grow abnormally and become melanoma during this process.
Tanning can be harsh to your skin. The light coming from the sun contains different wavelengths of ultra violet (UV) waves. The two types of waves concerned about are UVA rays and UVB rays. UVA rays are long waves that cause more damage than a UVB ray. UVA rays penetrate deeper into your skin and cause tanning (“The Dangers of”). More and more exposure to UVA rays can cause permanent damage ...
Tanning affects the human skin through ultraviolet radiation, part of the spectrum of light that omits from the sun to the surface of the earth. Ultraviolet A rays are the longer ultraviolet rays that are projected, and these rays penetrate deep into the layers of skin, causing a tanning effect (Harvard Women's Health Watch, 2). It does this by penetrating into the lower layers of skin, or the epidermis, and triggering cells known as melanocytes to make melanin, the brown pigment that causes tanning (Hyde, Patrice, MD, 1). They account for most of the ultraviolet components emitted by lamps in tanning beds, because they are associated with an almost immediate tanning effect (Brady, Mary S, 2). The shorter rays are ultraviolet B rays, and these rays only reach the outer superficial skin cell layer, also known as the epidermis (Harvard Women's Health Watch, 2). UVB rays, therefore, are the actual cause of sunbur...
One of the greatest accomplishments and innovations of human history thus far is the invention of the electric refrigerator. Such a simple concept has literally changed how the entire world stores food and has saved millions of lives in the process. Refrigeration as we know it has only been around since the 1930’s, and in less then a hundred years has been greatly taken for granted. Since the influence of electrical engineering in the modern refrigerator, refrigeration has gone from storing food in an ice cellar to being able to have two dedicating refrigeration units with controllable temperatures and even an ice machine attached. Without electricity modern refrigeration would be drastically different, using instead previous refrigeration
Melanin is the body’s way of protecting the skin this is why darker people tan easier because their melanocytes produce more melanin.
Melanin helps reduce the absorption of wavelengths into the skin (Chaplin, Jablonski, 59). The more melanin in the skin, the greater the protection against harmful UV rays, and the amount of melanin in the skin correlates with the skin’s color (more melanin means darker skin)....
In thermodynamics Refrigeration is the major application area, in which the heat is transferred from a lower temperature region to a higher temperature region. The devices which produce refrigeration are known as Refrigerators and the cycle on which it operates are called refrigeration cycles. Vapour compression refrigeration cycle is the most regularly used refrigeration cycle in which the refrigerant is alternately vaporized and condensed and in the vapor phase it is compressed. Gas refrigeration cycle is the well-known refrigeration cycle in which cycle refrigerant remains in the gaseous phase throughout the cycle. Cascade refrigeration are the other refrigeration cycles discussed in this chapter; absorption refrigeration is the one more refrigeration cycle which is used where the refrigerant is dissolved in liquid before it is compressed. One more refrigeration in which refrigeration is produced by passing the electric current through two dissimilar materials is called as the thermoelectric refrigeration.
Refrigeration Refrigeration is defined as “The process of removing heat from an enclosed space, or from a substance, to lower its pressure.” (First website given in bibliography) In simpler terms, it is removing heat from states of matter in order to keep them cooler. The basic need for refrigeration is to cool food and beverages, as they often get spoilt if the temperature is high. Before actual refrigerators and other such mechanical systems were introduced, it was very common for people to cool their food with ice and snow.
Cabernet Sauvignon Cabernet Sauvignon is one of the world's most widely recognized red wine grape varieties. It is grown in nearly every major wine producing country among a diverse spectrum of climates from Canada's Okanagan Valley to Lebanon's Beqaa Valley. Cabernet Sauvignon became internationally recognized through its prominence in Bordeaux wines where it is often blended with other red grape varieties. From France where it originated, the grape spread across Europe and to the New World where it found new homes in places like California's Santa Cruz Mountains and New Zealand's Hawkes Bay. For most of the 20th century, it was the world's most widely planted premium red wine grape, although that accolade is now held by Merlot.
Wine was a royal drink that kings use to drink, it was extracted from Vineyards. One of the oldest-known winery was discovered in the "Areni-1" cave in “Vayots Dzor”, Armenia. Since then wine was flourished all across the world. From a local consumption Wine became an International trading commodity. The older the wine the costlier it sells. Most of the wines are stored in wooden barrels, as it enhances the taste and colour of the wine.

Life changed immensely in the 20th century as air conditioning and refrigeration systems became more efficient and controllable. Air Conditioning and Refrigeration play important roles in providing human comfort, food processing, storage, and many other industrial processes. We chose this topic because our life would be difficult without AC and Refrigeration. This paper will talk about the history of air conditioning and refrigeration, the role of engineers in designing and building it, people’s life before and after air conditioning and refrigeration, and finally Applications in the area of achievements and future developments.
