But age as a signifer of quality is archaic, as distillers have gotten much smarter about how to make a good product rather than just letting things go for a long time and hope for the best. Honestly if you're buying a bourbon older than 10 years you're overpaying for diminishing returns. Most of the best bourbons/american whiskeys I have had are right around the $40-$70 range, and most don't mention age. I feel similarly for scotch but thats far trickier territory.

1) Virtually all commercially-produced liquor that has a flavor and isn't single cask is blended. The no-age-label is blended, the 16 is blended. The difference is in what they're blended with and how much.
2) Every study done of wine tasting involving brain scans shows that expectation modifies how taste is interpreted. So yes, to you, it totally did taste better, but not because it necessarily was better, from an objective standpoint. And at a certain level that'll be based purely on personal preference anyway.
Put the A'bunadh and the 16 Sherry in front of me blindfolded. I'll identify them every time.
People who make this wine comparison presumably don't drink much whiskey.
I've only tried the Ardbeg, and it's nice enough, but I'd call it a bit rough round the edges. Like tptacek, I'm wary of no-age, but if they get good enough to pass for long age complexity but bring them into my price range...
