Maybe if I explain to my wife tonight that it is International Whiskey Day, she'll go along with a double ration of rye for me...

(Unlikely. That woman can be very parochial.)

And in memory of our friend and Absent Comrade TexasStar:

Whiskey or whiskey—How to spell it?

Both spellings of the word, whiskey and whisky, are correct. The tricky part is matching the right spelling with the right country of origin. If you’re talking about a drink that’s been made in Scotland, Canada, or Japan, use the spelling without the e—whisky. When referring to drinks distilled in the United States or Ireland, use the e—whiskey. When pronouncing the words, you wouldn’t notice the difference, but it is apparent in writing:

I had a glass of Yamazaki whisky last night; it was OK, but it’s no Tennessee whiskey.

The difference also carries on into the plural. For whiskey, the plural is whiskeys. For whisky, it’s whiskies...
