I was seated next to Jean-Bernard Delmas, who at that time had been the wine maker at Château Haut-Brion and Château La Mission Haut-Brion for several decades. I had a yellow shirt on, my only shirt whose sleeves were long enough to get past my jacket sleeves, showing the cuffs. I spilled some Château Haut-Brion on the yellow cuff and of course everyone at the table began making a joke of it. Jean-Bernard cocked his head, handed me a bottle and said,

"The only way to remove that stain is to pour some Château Laville Haut-Brion on it!" 

Which I did. And it did.
