Nose: Very close to the 1968 OB, with smokier and some plumps flavours.
Diluted, the nose gets closer to the OB, but with apple flavours.
Taste: Bitter, floral (lilac and narcisse /jonquil), smoky, slightly peaty,
tobacco, cooked fruits, pineapple and Darjeeling tea. The finish is quite long,
slightly bitter (dark chocolate), fruity and with toffee. The sherry influence
is quite discreet. Dryer than the DT.
General Impression: the driest of the 3 BenRiach 1968, but also the smokiest.
They are all excellent variation of the same whisky and it is difficult to say
which one is the best one. Try them and make your own opinion.
