Wine growing is spreading across the USA

Apparently there is wine grown in every state but one in the USA (no prizes for guessing which state has no wine). Here are some examples:

• North Carolina (with a NC wine quiz): Winemakers hoping for the perfect crop
  
• Idaho wine industry seeks its place in the sun
  
• Colorado: High country wine
  
• Virginia: Dry, hot summer could add up to good year for Virginia wine
