In many cases it's a hype cycle. It's possible that specific years really are excellent. But it's impossible to know unless you get in at the same time it is blowing up. Once it's been hyped, it's hard to obtain, hard to live up to, and sometimes quality goes down as supply ramps up (although with aging it's not ramping up fast).
