Are there any English whisky distilleries?
Not so far as I know. Welsh whisky is just a marketing gimmick, Irish is “whiskey” with an “e” and completely different stuff but Scotch can come only from Scotland. There would probably be very little point in a distillery company producing in England since there would be no market for the stuff and, if they used it in blending, I assume that would prevent them from calling the stuff “Scotch Whisky”.
