I think the Blue is a blend, not a vatted. Someone bought me a glass once-- it's very good, don't get me wrong, but it's not all that interesting. Very silky smooth mouthfeel (probably from old grain whiskeys in the blend), and fairly light and sweet. Their Green label was the vatted malt, 15 y/o I think, not sure if they're still making it. It was overpriced by about 30% but if you found it on sale it wasn't a bad value. Frankly, though, there are plenty of single malts with a similar profile at the same price or lower that are better...Clynelish and Springbank come to mind immediately.
