It's an old, old, blend, real big in the 40's - 50's. You can drink it and pretend you're partying at David Niven's place. It's got a cool label with some terriers on it. I think it's a Diageo product currently.
As blends go, the current incarnation (who knows if it's anything like its ancestors) is decent enough stuff - better than, say, Old Smuggler, but not as good as Teacher's/White Horse/Grouse. It has a touch of peat in it, and makes a servicable scotch & soda. If you can get it cheap (it's around $15US around here) it's not bad, but I wouldn't pay more than that.
I remember it is what Marcello and Papparazzo order in the bar when his father in La Dolce Vita. I bought a bottle several months ago and I think that it is basically just the quintessential average scotch. It is simple and pleasent enough that I don't think anyone could really dislike it, but plain enough that there's not much unique to it that could make you really like it over other brands. It is fairly sweet and a little bit smokey.
It's not a bad choice if you see it on the shelf and want to try it out, but I don't think it's remarkable enough to be worth going to lengths to seek out.
This was one of my favorites when I was a young man (about 40 years ago). I can't say for sure what I would think of it now, but I used to really enjoy it. It used to be a pretty well respected brand until the single malt craze started in the mid-70's. Nowdays, no blend gets any respect.
If you enjoy blended scotch, I would say try it. Others to try would be Grant's, Teachers, and The Famous Grouse.
I found it a store last year for $11 a liter. I liked it alright, and supposedly it was the only scotch James Bond drank in the movies, so that's a plus. I went back to buy another bottle at the store and they wanted $30 for it.
