Wine is not a very tolerant liquid; it gets messed up when exposed to certain conditions. According to scientific research, it has been found that the taste and value of wine can be affected by three major factors which are temperature, light and humidity. When wine is exposed to these three factors in excess, the value of the wine depreciates with time until it actually loses its taste completely. This is why wine coolers are necessary to keep wine under the right conditions, away from too much light, temperature and humidity.
