Points of trivia:
5/24 is the anniversary day of the Judgment of Paris, 1976. Stag's Leap Wine Cellars, 1973,Cab Sauv was the winning red, Chateau Montelena,1973, Chard the winning white.
5/21 was National Chard Day.
As if justification needed....Cheers!
Note: above edited per David's comment, below. There are so many "days" it's challenging to keep track.
Variety of sites on Google list International vs. National Days. Rather confusing.
