I could be mistaken, of course. But if memory serves me well, this was an upscale blended whisky bottled by the company concerned, and not a malt whisky from a single distillery. I also seem to recall that a friend of mine was gifted one some time ago.
No, in fact I'm not mistaken!
I found an old catelogue from my local whisky specialist outlet dating back to the spring of 1999 and, sure enough, there are listings for 3 such whiskies issues by the Speyside Distillery Co... a 21YO, a 25YO and a 30YO. respective prices were CDN$122.75, CDN$177.25 (for the 25YO) and CDN$343.
There you go.
