A Bit About Wine
What is wine?
Wine has been made for 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?
Yeast is the magical ingredient that turns grape juice into wine. Interestingly enough, there is actually wild yeast spores in the air and all that is really needed to make wine is an open container of grape juice and time. The result however, would probably not be the most palatable of beverages.
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?
There are black grapes and green grapes and grapes of various gradations in between. Regardless of the color of the grape the juice is always clear, or nearly so. If the skins are left in the juice during fermentation, a red wine is the result. A white wine results when the skins are removed.
Even though there are very few ingredients, there are many things which influence the taste of wine. First of all, there are many varieties of grapes. Each grape variety will produce different flavors, aromas, and even textures. In addition, the soil and climate where the grapes are grown drastically affect these variables. Not only that, but the wine maker can control various things by the technique, temperature and yeast used during fermentation. Other variables such as fermenting or storing in oak barrels will also affect the taste.
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.
Clearly, this has been a quick overview of wine, but hopefully it has filled some of the voids in your understanding of this historic drink.
