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. Since it began in the 1820s, wine-production in Washington state has gone from strength to strength, with many of the finest United States wines coming out over the past twenty years hailing from this region. Today, the state is the second largest US producer of wines, behind California, with over forty thousand acres under vine. The state itself is split into two distinct wine regions, separated by the Cascade Range, which casts an important rain shadow over much of the area. As such, the vast majority of vines are grown and cultivated in the dry, arid desert-like area in the eastern half of the state, with the western half producing less than one percent of the state's wines where it is considerably wetter. Washington state is famed for producing many of the most accessible wines of the country, with Merlot and Chardonnay varietal grapes leading the way, and much experimentation with other varietals characterizing the state's produce in the twenty-first century.
