Is it "whisky" or "whiskey"?

The short answer is that malted spirit that comes from Scotland or Japan is spelled whisky (without an 'e'), and the same style of spirit from other parts of the world, especially Ireland and the United States, is spelled with an 'e'. A deeper dive into the differences can be found here.

You might have noticed that this website's address is mywhiskyvault.com, where whisky is spelled without an 'e'. However, if you try to navigate to mywhiskeyvault.com (<-- with an 'e') you will also be brought here. Since our initial focus is on single malt scotch here, we have branded our website using 'whisky', but we support all types of whisk(e)y here.

In the end, it's what's in your glass that matters, regardless of how you spell it.
