This is how I rate the 1972 Brora I have tried.

1 - 1972 29 year 59.5% Douglas Laing Platinum

2 - 1972 22 year58.7% Rare Malts OB

3 - 1972 40 year 59.1% Travel Retail Exclusive

4 - 1972 1st Annual Release 30 year 56.3%

Although I gave 1 & 2 96 points the DL edges it for me.I did not include any 1972 G&M Connoisseurs Choice because they are only 40%.

This review is from a decent sized sample.

Nose: Completely different than the Special Release! Smoky, peaty and very farmy. Coal, ash, motor oil, hot asphalt, wet hay and tons of peat bales. Wax, tobacco, cigar box, humidor and only subtly-sweet tropical fruit flavors that try to force themselves through from time to time, but are quickly subordinated again. One of the "dirtiest" noses ever - awesome !!!
Taste: What a power! Incredibly dark, smoky and "dirty" ... again in the taste again lots of peat, coal smoke, wax and only subtle fruit notes, which are lined with honey and vanilla. A taste that you will not forget !!!
Finish: infinitely long loops! The finish reflects the nose and the taste completely - great! An absolutely dark part full of peat and tar flavors.
Remark: The aromas stick to your palate for a week ... just awesome!
96 points (nose: 95 / taste: 97 / finish: 96)

I like Brora very much - especially the smoky and leathery ones. This one is really smoky - almost becoming a bit Ardbegish.

This Whisky was sold for 2.805 € at Whiskyauction in March 2015

N: Sweet, fruity organic cow-dung in the face. This dram will time travel you back to the 1970’s to a farm on a hot summers day with an ice-cream shop next door. Order a light white vanilla ice-cream with passion fruits and bubblegum - a tutti-fruity then! Super fresh and vibrant.
T: Husky, oily, mineral peat… then heat <<. Add water for a creamy, milky, viscous body like congealed blood - not that i’d know, or like the mouth residue after eating peanut butter and honey mixed with saliva. Sounds charming i know, but we are talking about chemistry and biology here. Another textural gem of the highest accord.
F: The impact is so huge on arrival and development, the finish for me begun with head wagging and dad-noises followed by a stunned awe-inspiring silence and a ‘wow’ at the death.
C: You’ll be hard pressed to find a finer whisky, ill get a bottle...oh wait!, £3400? [Oct ’14] - aah maybe not.

Scores an A++

@Feusi: you are right about Serge's rating for this whisky. But meanwhile, another 1972 Brora has topped the list of his ratings: the 40yo OB (98 points)!
