Harvest is primarily determined by the ripeness of the grape as measured by sugar, acid, and tannin levels with winemakers basing their decision to pick based on the style of wine they wish to produce. The weather also shapes the timing of harvest with the threat of heat, rain, hail, and frost, which can damage the grapes and bring various diseases.
What is the difference between Pinot Gris and Pinot Grigio?
Pinot Gris and Pinot Grigio represent not only a different language, but a different wine style as well. The French variety, Pinot Gris, is best known for the soft, aromatic wines it produces in Alsace, Franc. Pinot Grigio, the Italian name for the grape, produces wines that are crisper, more citrus-driven in avor, and lighter bodied in style. Outside of France and Italy, producers of the grape use the name (Pinot Gris or Pinot Grigio) that best represents the style they are aiming to create.
