Guessing you're referring to "Glenfiddich", but it reminded me of the case of whiskey vs. whisky:

It's generally spelled “whiskey” — with an e — in the United States and Ireland. It's spelled “whisky” — without the e — in Scotland and Canada. Since this article is about Glenfiddich, which is based in Scotland, it makes sense that it's spelled without the e.

The reason for this is purely historical — there's not necessarily a difference in the product. That said, "Scotch" must be produced in Scotland, and hence you'll always see "Scotch whisky" (no e).
