Red ZinfandelZinfandel is known for its blush-worthy red wines, and the California wine grape is also known as the "lady's slipper." Red Zinfandel grapes are prized for their naturally deep color. This deep color is a result of the high amount of melanoid gene expression that has been allowed to occur throughout the grape's development. The extreme color of Red Zinfandel grapes also contributes to the wine's reputation as a very versatile vintage grape. Red Zinfandel can be used to make an abundance of red, flavored wines, white wines, sparkling wines, saisons, and sherry. Red Zinfandel is well-known throughout the United States for its wide variety of flavors. Winemaking has long acknowledged the flavor variations present in various grapes. Grapes vary in their tannin levels and the degree of acidity or subtlety they have. The darker reds are known for having deeper colors, while lighter colored grapes are said to have more subtle flavors. The more melanoid-carrier genes present in the skin of grapes contribute to the deep color and flavors of red Zinfandel grapes. The grape is named after its natural shade of reddish pink color, which fades over time, but remains vibrant and bright in color. White Zinfandel grapes are grown in the cooler climates of northern California, with the cooler climates of the central and southern parts of the state contributing to the white coloring of the grape. The closer to the equator that one lives, the lighter the red or white Zinfandel will become. Also, the shorter summers of California will produce a lighter golden color for the grapes. In the years since the late 1970s, the number of vineyards dedicated to producing this grape variety has greatly increased. Because of this increase in cultivation and growing areas, there has been an expansion of the different types of Zinfandel varieties that can be grown. Some of the most popular are the white and red Zinfandel. Although red and white grapes are commonly grown together, it should be noted that they have slightly different characteristics and taste. White Zinfandel is often thought of as an inferior variety due to its lower sugar content. However, this grape varieties is actually one of the best types of grapes grown because of its ability to produce good quality white wines, usually with a lower alcohol content than other types of wine. The reason for this is that the alcohol in white wine can actually be reduced without reducing the flavor. Another advantage is that this variety is not highly prone to diseases, unlike other grape varieties. Italian primitivo is another type of white wine grape that is commonly grown in Australia. The name is derived from the place of its origin, which is Tuscany, Italy. Italian primitivo is commonly used to make low-alcohol white and red wines. It is noted for having balanced flavor and body due to its medium starch level. Although Italian primitivo is popular and suitable for low alcohol production, it is not considered as appropriate for production of high alcohol products. This variety of Zinfandel is popular in Australia because it produces great tasting wine. The grape varieties used in this process of fermentation are usually cross-ripe. In the days when Italian wine was first crafted, this specific grape was cultivated only for its fruit and for grape juice extract. This is also a great variety of red wine grape that is suitable for making good wine. Red Zinfandel grapes are suitable for use for the creation of several rows. These grapes were originally harvested in the states of Tennessee, Arkansas, and California. It is interesting to note that the state of Arkansas had been the main source of loss grapes for decades.
