Bonterra Wines, the world's best selling wine made with organic grapes**, knows what it takes to find a balance between preserving nature and producing an award-winning product. As the Official Wine of The PGA of America, Bonterra is committed to helping golf courses find their balance between the environment and the game of golf. That's why Bonterra is working with Audubon International to "Green the Greens" at courses across the U.S. From September 17, 2008 until the end of the PGA Tour season (11/10/08), a limited number of golf courses can join the Audubon Cooperative Sanctuary Program for Golf Courses (ACSP) on Bonterra's dime. (See "How it Works" for details). The ACSP is an award winning education and certification program that helps golf courses protect the environment and preserve the natural heritage of the game of golf.  57% of Golf Digest's® Top 100 Golf Courses for July 2008 are ACSP members, including seven of the top ten.
