what is the difference of blue label whiskey?

Answer 1

The age. I'm not sure what the time frame is, but blue label is aged in charred oak barrels longer than say....red label, or black label.

Answer 2

In the case of Johnny Walker blue label, the blend contains better whiskys and is probably aged a bit longer than black label. Some distilleries blend their whiskys and then let them sit in the cask together for a while to blend, sort of like certain sauces and soups improve on the second day once they have steeped a bit.

I have never had blue label, but black label is great for a casual scotch drinker. Purists might turn their noses up at it because it's a blend, but I'd gladly take a dram of J.W. blue over Laprohaig, Glenmorangie, Glenlivet, etc. if I had the chance, just to know what a really expensive blend tastes like.

There are other whiskys out there that have different color labels to indicate different aging techniques--different casks (sherry, bourbon, etc.) and durations of aging. One blue label does not equal the next. Some purists, again, say that all of this is gimmic and obfuscates the whole point of scotch whisky. Others say that all but the very best scotches could perhaps use some obfuscation to make them more palatable.

Answer 3

Blue label is aged 25 years. Expensive but if you're a scotch drinker, buy it every other year and enjoy is slowly.
