Made in a former Karuizawa still, the Shizuoka Prologue K is one of the best young whiskies I've ever tried and a very good single malt regardless of age.
Karuizawa prices are madness, but when you taste one you can at least understand where the hype surrounding this closed Japanese distillery comes from. This one was distilled in 1975 and bottled in 2010 for Whisky Live Paris.
