California as a wine producing region has grown in size and importance considerably over the past couple of centuries, and today is the proud producer of more than ninety percent of the United States' wines. Indeed, if California was a country, it would be the fourth largest producer of wine in the world, with a vast range of vineyards covering almost half a million acres. The secret to California's success as a wine region has a lot to do with the high quality of its soils, and the fact that it has an extensive Pacific coastline which perfectly tempers the blazing sunshine it experiences all year round. The winds coming off the ocean cool the vines, and the natural valleys and mountainsides which make up most of the state's wine regions make for ideal areas in which to cultivate a variety of high quality grapes. The purple Malbec variety grapes which now grow all over the Old and New Worlds had their origins in France, where they are one of the few grape varieties allowed to be used in the highly esteemed blended wines of Bordeaux. However, it is perhaps the New World Malbec wines which have attracted the most attention in recent years, as they thrive in hot southern climates in ways they cannot in their native country, where the damp conditions leave them highly vulnerable to rot. Malbec grapes are renowned for their high tannin content, resulting in full-bodied red wines packed with ripe, plummy flavors and held in their characteristically dark, garnet colored liquid. In many countries, Malbec is still used primarily as a varietal for blending, as it adds a great level of richness and density to other, lighter and thinner varietals. However, single variety Malbec wines have been greatly on the rise in recent years, with some fantastic results and big, juicy flavors marking them out as a great wine for matching with a wide range of foods.
