(FoxNews) - In case you haven't heard, May 23 is National Chardonnay Day.  

It is so much more exciting than Tax Day or Arbor Day, and clearly a great reason to pour a glass of wine.

To the surprise of many, chardonnay is America’s most popular wine (yes, over red) and the world’s most widely planted white wine grape.

And I know you’re thinking:  'But what about the great big red cabs coming out of California? They must plant more red grapes than white?'

Nope.

“Chardonnay is the most widely-planted white grape in California, with 95,000 acres, spread widely throughout the state,” says Tom Matthews, the executive editor, at Wine Spectator Magazine.
