This Brora 21y 1977 RM generally gets better reviews than its 1982 RM brother. The two 1972 versions in the Rare Malts collection seem to be the best though (SV scores them 96 and 97 and other MM seem to agree).
Brora 21 yo 1977
(56,9%, Rare Malts 1998)
Nose: it shares a similar profile with the Brora 20 yo 1982, but this one is slightly more exotic with banana and coconut. Some juicy yellow grapes. Quite a few floral hints. It’s less austere with more spices. Wood chips. Hints of heather. No farminess and still relatively low peat levels, but complex.
Mouth: very powerful, sweeter than the 1982 version, more honey and vanilla with more oak as well. The same fat, oily mouth-feel. Soft, sweet peat. A salty edge (seaweed). Spices. Lemons. Slightly nutty.
Finish: a very similar peppery kick with a slightly woody / salty aftertaste.
In line with the Brora 1982, but slightly more complex and more powerful in all directions (bigger fruitiness, sweeter, more oak, but a more alcoholic character as well). Very rare now and more valuable than the 1982 version. Around € 300 unless you find an occasional bargain.
Score: 92/100
Johan, who provided my sample (thanks) has tasted a lot of Rare Malts Brora. If you understand Dutch, check out his notes.
