USA - California 

California is today one of the most interesting realities in the entire world wine scene; this is also thanks to the fact that, without constraints linked to rooted traditions (its viticulture is recent), it can freely experiment in various fields. The Californian style is in many respects based on the French one, in particular, the production areas of Bordeaux, Burgundy and the Rhone Valley are seen as models. Even the vines grown in California clearly reflect the production choices of the region. Apart from Zinfandel , a close relative of Primitivo, the grapes used in Californian wines are mostly "international", and to a small extent also Italian. Among the white grape varieties the most common is Chardonnay and for the black grape varieties Cabernet Sauvignon. The other white berried grapes grown in California are Sauvignon Blanc, but also Riesling, Pinot Bianco, Pinot Grigio, Sémillon, Viognier, Chenin Blanc, Gewürztraminer, Colombard, Marsanne, Roussanne and Moscato bianco. The other most important black berried grape varieties are Merlot, Pinot Noir and Syrah followed by Carignan, Grenache Noir, Malbec, Mourvèdre, Petite Sirah, Petit Verdot, Barbera and Sangiovese. In California every type of wine is produced, from whites to dry reds, sweet wines and also some interesting Classic method sparkling wines.
