I read a good blog post this morning on the idea that “lower yields always leads to better wine”.  The blog points out that vine balance is the key, not the crop load.  Read the blog here: http://artisanfamilyofwines.com/blog/?p=31

If you wan to learn more about vine balance, read the basic concepts here written by Dr. Patty Skinkis at Oregon State University: http://www.extension.org/pages/33109/basic-concept-of-vine-balance and how vine balance is important in vineyard design written by Dr. Jim Wolpert at UC-Davis: http://www.extension.org/pages/31779/vine-balance-and-the-role-of-vineyard-design

This articles give a great overview of what vine balance is and how it affects the overall health and fruit quality in the vineyard.  Good stuff.
