Scotland
Johnnie Walker Green Label is a blended malt made entirely with single malts from the four corners of Scotland and aged for at least 15 years. It's one of the best bargains in Scotch whisky and a favourite among bartenders.
The nose is quite rich and full. There are notes of mochaccino and espresso coffee, wood smoke and a fireplace, as well as a touch of bitter chocolate and oak.
The palate has a medium-body with notes of crisp cereals, coffee beans and chocolate, a date note with a touch of walnut.
The finish is quite long and spicy with honeyed sweetness and oak.

I don't agree with the description above. Maybe it's not the same whisky it was at 2010. Specially at palate, it taste a bit spice, like pepper.
If anyone is traveling internationally, check out Johnnie Walker "Island" Green Label, a special duty-free release, which has a slightly different blend, mixing in a little bit more of the smokey Isla malts to give it an extra punch. I bought a case of old Green Label prior to its discontinuation. It was temporarily discontinued world-wide, because the recipe was starting to noticeably change, as some ingredients were falling into short supply. Towards the end, it was a bit less smokey than the original recipe. After supplies were allowed to be replenished, Green Label was relaunched, returning to the original recipe in full measure. Personally, I can sense very little difference between the old and the new. I always tell me friends that if you were to have a theoretical scale of 1-10 for smokiness, the last batch of old Green was maybe a 4, new Green is maybe a 5, and "Island" Green is about a 5.5. It's an interesting exercise to taste all three back to back. I honestly think that this is the greatest blend of all time. Being what was previously called a "Vatted" malt, this is a blend of 100% single malts, and not a drop of the cheapo grain whisky. This Green Label should inspire people to be adventurous, and try mixing together 2 or 3 of their favorite single malts, which they think might go well together. Get a nice 350ml decanter, and fill it up with three or four single malts from different distilleries, and let them get to know each other for a few months, and then see what happens!
For me this is decent, considering it is a blended whisky. Smooth with hint of wood and sweet notes. The finish is spicy and not as long as i like it to be. This is a good choice if blue label is too pricey. Dont think it should be a 95 pointer though.
Nothing spectacular, quite sweet. Good for beginners. Smooth finish.
I'm giving this whisky such a high rating because of its value. The age statement gives some intrinsic value and the price makes it incredible. I've had the blue a few times but I doubt I'll ever buy a bottle of it while the green 15 is as good as it is for nearly a quarter the price. Price aside, it has amazing flavor, especially for a blended. It's slightly delicate for a JW but it does not disappoint.
