**Updated by Greg Jones in 2010 (added 1a, extended V)

1,500 - 2,000 = Region Ia
2,001 - 2,500 = Region Ib
2,501 - 3,000 = Region II
3,001 - 3,500 = Region III
3,501 - 4,000 = Region IV
4,001 - 4,900 = Region V

Question 3

Climate Change

Answer 3

• Didier Gimmonnet harvests, on average, 21 days before his father did and generally produces higher yields.
  
  • But he says his dad, in a good year, would get 8.5 TA at 10% ABV. Today, Didier says a 10% ABV Champagne would not have ripe flavors. Today he believes you need 11% to taste ripe, and acids are typically 6.5-7.5 TA
• Rodolphe Peters’ dad used to do all wines with complete MLF. But Rodolphe moved to partial MLF in 2005 because of warming climate.
