When it comes to New World wines, and especially wines from the United States of America, Napa Valley is something of a standard bearer. Over its relatively short history, it has managed to transform itself from being a fairly insignificant region, to becoming one of the most important and highly regarding wine locations on earth. With an ideal climate for viticulture, blazing sunshine and a low level of rainfall, this valley is shielded on many sides by mountain ranges which help it maintain a consistent level of heat, light and moisture throughout the year. Today, Napa Valley is a home of innovation and quality, with dozens of grape varietals thriving in the fertile soils. However, the main varietals grown there have always been Cabernet Sauvignon, Chardonnay, Pinot Noir, Merlot and Zinfandel, and the wines they produce are constantly lauded by critics and competitions across the globe. The Pinot Grigio or Pinot Gris grape varietal is now one of the most widely grown vines in the world, due to the surge in popularity of Pinot Grigio wines over the past twenty years or so. These grayish-blue fruits, which hang in their distinctively conical bunches, are responsible for a very broad range of wines famous for their variety of color tones and flavors Pinot Grigio varietal grapes are highly influenced by terroir, climate and particularly the skill and expertise of the vintners who process them. As such, there are full bodied, amber colored wines made from this grape, and there are equally delicious yet far leaner, paler, lighter bodied and crisp white wines made from the same species in other parts of the world.
