Lagavulin 12 yo (43%, OB, White Horse Distillers, UK, +/-1979) We've tried other variants of the well-known 'white label' but this one has the bottom of the label printed in black instead of red, so it's rather from the late 1970s if I'm not mistaken, so one of the very last versions before they launched the 'green on cream' label. Colour: orange gold. Nose: makes you cry. I mean, it's not huge, it's not wham-bam and it's not even very smoky, but it's perfect. As often, there's this feeling of smoked oranges on a bed of ham and kippers, with some dried seaweed, tar, coal, motor oil and just touches of chocolate. One of the unbeatables. Mouth: waaaaah! I'll keep this short and sweet: please call the anti-maltoporn brigade. Having said that, I know some malt lovers who'll find this too dry and ashy, but that's precisely what I love in this whisky, amongst many other things… Finish: amazingly long and big at 43% vol. More extreme tar, earth and brine in the aftertaste. Comments: to think that in some countries, they would have given you one bottle for free if you bought a case of cheap rum! Indeed, few people were buying it… But maybe that's why you can still find it if your wallet isn't too flat. Anyway, it's glorious, classic whisky. SGP:457 - 94 points.
