The Basics of Wine – Grapes, Yeasts, Age, and Taste

A basic knowledge of wine can help you select a fine bottle. Read on to learn more about grapes, yeasts, age, and taste. We’ll also discuss what each factor means in the wine. And don’t forget to taste a few different wines to learn what makes them different from one another. It’s really easy once you know the basics! To get started, let’s talk about grapes. Grapes are the most important factor in wine, so learn about them!


Yeasts in wine are microscopic organisms that grow on the grape skin during the fermentation process. During this time, they produce useful hydrolytic enzymes known as b-d-glucosidases. These enzymes break down the grape’s sugar into alcohol, but they also produce other substances that change the final flavor and aroma of the wine. Listed below are some of the more common types of yeast in wine.

High cell density ratios of non-Saccharomyces yeasts and S. cerevisiae yeasts have been associated with the production of compounds detrimental to wine quality. Therefore, winemakers should use only yeasts that have the proper cell density ratio for the wine they are attempting to ferment. This way, they can better control the fermentation process and produce better-quality wine. While it is still necessary to monitor and control the growth of these microorganisms, there is a growing interest in the use of these organisms in innovative winemaking.


The fermentation of grape juice yields wine. The fermentation process uses yeast and sugars, which turn the fruit into ethanol alcohol and carbon dioxide. Grapes accumulate sugars during the growth phase through the translocation of sucrose molecules from the leaves. These molecules hydrolyze during ripening to form glucose and fructose. About 15 to 25% of a grape will be composed of simple sugars like glucose and fructose. These two are six-carbon sugars with no other chemical compounds.

A single 750 ml bottle of wine can contain anywhere from 600 to 800 grapes clusters. This amount varies depending on the grape variety and the wine. Approximately seven to 10 pounds of grapes grow on one grape vine, and each cluster can produce about six to eight bottles of wine. Grapes in wine can grow in nearly any climate, but are known for their difficulty in growing. Grapes can be cultivated by following instructions and learning about the growing process and the best varieties for winemaking.


One way to tell the age of a wine is by its color. The wine’s color is like the rings of a tree: the color is the first indicator of its age, while a garnet red indicates that the wine has reached its peak of maturity. A red wine that is older, but still healthy, is usually a brown color. This color indicates the wine’s age, and can give it clues about the flavor of a bottle.

In addition, the taste of a wine changes as it ages. A young wine will fill your mouth with bitter, tart taste. An aged wine, however, will be smoother and softer in flavor. Young wines will smell like ripe berries, while aged wines will have a strong aroma of earth or leather. However, young wines will still have the characteristic sourness and musty aromas that make them unpalatable.


When you taste a wine, you are judging its overall quality. The taste is the sum of four basic characteristics. The fruit level determines the flavor profile of a wine, while the residual sugar determines how sweet it is. The body and finish describe how the wine feels on the tongue. You can also compare the sweetness of a wine with that of a different type of wine. If you are a beginner, try learning about the differences between each of these categories to improve your tasting experience.

Your nose gives you valuable clues to determine the flavor and classification of a wine. However, it is important to remember that your ability to recognize aromas depends on your memory. If you have never smelled a fruit before, for example, you may find it difficult to describe a fruity wine by its aroma. The taste of wine also affects the emotions and the value judgment of a drink. While you may be able to describe a fruity wine based on the scent alone, you may struggle to describe that taste when you do not know the aroma.


There are different styles of white wine. For instance, Chardonnay is a classic aromatic white wine. Chardonnay grown in warmer climates is considered better than that produced in colder ones. Viognier is another great aromatic white wine. Aromatic grapes date back thousands of years and are some of the oldest varieties of wine. Ancient Egyptian queen Cleopatra was a fan of Muscat of Alexandria. Aromatic white wines can be sweet or dry, but they tend to taste sweet due to the perfumey aromas.

The style of a wine has a lot to do with the way it tastes and is paired with food. Learn about different styles of wine by purchasing a guide such as Wine Folly – The Essential Guide to Wine.
