To 'E' or not to 'E'
The difference in the spelling is mostly just a regional preference (think "color" in the States vs "colour" in the UK). While whisk(e)y is produced all over the world, the big players in the game are the United States, Scotland, Japan, Ireland, and Canada. The U.S. and Ireland typically spell the word with the "E": whiskey, the others such as Scotland and Japan usually prefer whisky. There are some exceptions to the generally perceived rule, Maker's Mark being the most notable. The omission of the "E" in Maker's Mark is an homage to the Scottish heritage of the producer.
We can't think of another nationally revered holiday that's as indebted to whiskey as St. Patrick's Day. (Okay, maybe the Kentucky Derby, but we'll revisit that in May.) You may notice that we offer single Constance decanters with two different spellings of the spirit, but have you ever wondered why?
Some die-hard whisk(e)y aficionados believe there's more to it than simply etymology: that the choice of spelling reflects on the overall flavor of the spirits (such as the strong correlations between Scotch and Japanese whisk(e)y). We can promise you, Reclamation Etchworks spared no expense to research these differences exhaustively. At the end of this investigation, we've found that we like them all. Probably best to keep one of each decanter around, just to be savvy in any possible situation...
