In California, every grape has its own unique character and flavour, and thus are all treated and cared for differently. These traits shape the important characteristics which are found in Californian white wines. The American vineyard management techniques mean that most vineyards in California only plant the grape that is best suited to its soil types and weather. This allows the grape to reach the desirable level of phenolic ripeness that the grower is seeking. Today in America wine is made in 50 states, and although the soil and weather diversity means that they have the potential to grow hundreds of grapes, the Americans focus on what they have learnt from their experience, concentrating their techniques on the most important grape varietals that are planted in California.
In California, more than 60 different varieties of grapes are planted for use in making wine. California’s most popular white varietal wines that have grown from this experience are Chardonnay and Sauvignon Blanc. Other widely available Californian white varietals include Riesling, Chenin Blanc, Pinto Grigio and Gewürztraminer. In America, varietal wines are named after their sole or dominant grape variety. U.S federal regulations dictate that a wine must derive at least 75 percent from the grape variety that’s on the label.
