Wine is an alcoholic beverage made from fermented fruit juice (usually grapes). This is, arguably, the most elaborate drink developed by humans. The best wines are a result of the very complex interaction between the biochemical development of the fruit, reactions involved in fermentation and human intervention in the overall process. Wine has always played an important cultural, nutritional and religious role in human society. Weddings, anniversaries, birthdays, graduations, religious rites, promotions and other significant events are often accompanied by a glass of this noble beverage. Aromas and flavors of certain wines are often etched in our memories sending us back to the greatest days of our lives.
