What is wine?
Wine has been made for many centuries from just two simple ingredients: yeast and grape juice. Actually, just about any fruit juice can be used, but by far the majority wine is made from the juice of the grape.
Historically wine was the drink of choice because of the sometimes poor quality of the drinking water in so many regions. Today, of course, we tend to open a bottle of fine wine at times of celebration or offer it as a welcome gift as part of a wine giftbasket.
How is wine made?
Since there are yeast spores in the air, wine could be made without effort simply by allowing grape juice to stay in an open container for an extended period of time. You probably wouldn’t find that so enjoyable, though.
Yeast is a living organism. In wine making, the yeast feeds off the sugars. That process is called fermentation. The action of fermentation converts the sugars in the juice into alcohol with a biproduct of carbon dioxide. In contemporary times, special types of yeast have been cultured solely for their use in wine making. The particular strain of the yeast, along with other factors, determines the flavor of the wine.
The wine is removed from the original container and placed into another container in order to mature before bottling. The yeast stays in the original container.
How does wine get its color?
You probably know that there are green grapes and black grapes and different grapes are used to make different wines. The color of the wine, however, does not directly reflect the color of the grape. In fact, grape juice is largely clear no matter the color of the original grape. The color of wine is determined by whether (and for how long) the skin is allowed to remain in the juice during the fermentation process.
What gives each wine its taste?
Many factors contribute to the eventual flavor of any wine. They include the strain of yeast, the type of grape, the soil conditions, the weather during the growing season, the technique and temperature during fermentation and even the nature of the oak barrels in which the wine matures.
Never fear, with all of these factors considered even the most avid wine drinker would ever be able to experience all of the different varieties of wine on the market today. Let the treasure hunting begin!
What is tannin?
All wines have tannin. That is the component that provides that sort of drying feeling on the tongue. It comes from the stems, seeds and skins, so red wines will have more tannin than will white wines. That accounts for the different tactile feeling between reds and whites.
Because of the brevity of this description, this has been only a tiny overview of what there is to know about wine. Hopefully, though, it has given you a few nuggets for your conversation at the next wine and cheese tasting that you attend.
