Master of Malt previously sold separate samples of the 1997 Clynelish Berry/Boisdale 2012 bottlings, namely the 14yo and the 15yo - and the two profiles were very different indeed. The 14yo [catalogued here] was very poor but the 15yo was splendid. I ended up buying a bottle of the 15yo but I was unable to identify whether it was the 14yo or 15yo via the bottle or label as both were distilled in 1997 and bottled in 2012 and no further information was given. MoM assured me i had been sent the 15yo bottling.I can only conclude that Berry and Rudd bottled two batches from the same cask - the first batch being bottled shy of the full 15years and the second more superior batch being bottled later in the year of 2012 technically making it a 15yo. Furthermore as this cask was bottled for the Boisdale group to be consumed by patrons in their restaurants, there would be no importance attached to indicating first or second batches on the labels, only that the whisky was bottled in 2012. What is very odd is how different the two samples were!
Below are my tasting notes from both the 14yo and 15yo samples:
14yoN: Smells like a Speyside/Highland blend as sherried fruit grainy malt. Gentle sweet nose but the definition is muddled. There is actually a soil note, some dryish grass, ground almond flour and.. peanuts? Lemon juice coming through. Overall, an inviting gentle sweetness to the malt.
T: Pepper chilli on the front of the nose with juice bursting out of the spice bomb. Theres a hot bitter edge here. Needs water, but it doesn't help
F: The heat eases now but my peppered tongue is still throbbing. Muddy tannins and more soil. Old chewing gum with old bitter rosemary, uugh. Maybe some sweeter fruits are trying to come out here, but all thats arriving is very sour grapefruits and some drying wood tannins at the death
C: The nose is pleasant if muddled and literally muddy whilst the palate is a pepper attack followed by some old green spearmint bitterness. Tastes like a good spirit that didn't have a good marriage in the cask. J Murray scores this cask 93.5. WB 79 
N: Compared to the 14yo Boisdale, the 15yo displays much clearer fruit notes within a charming sweet honeyed grain package. Unlike the 14yo, theres no muddiness, it is a perfectly simple and superb malt with an abundance of honey, sweets and fruits on show. Marzipan and sugar icing coming out now with pepper and orange wood varnish [if that was a thing]. It's all rather delicate.
T: Much more sugary and buttery, peppery like the 14yo but the sweetness is still in tact and balanced with the pepper - a great combo. Later - banoffee pie, kale, anise and nutty with a surprising speysidey biscuit note.
F: Now the wood and herbal tannins come through but the malt conquerers them on a splendid journey. At the death, an amalgamation of wood, herbal [salty notes] and the gentle malt itself which displays sour and majestic grapefruits. Add water to accentuate everything but the pepper, on the front of the palate. Its more creamy now, those bitter maritime notes are stronger too. Its one to add water in the mouth and alternate with neat. Medium finish, dark and white chocolate
C: My 14yo Boisdale was not great but this is a good one. Not an easy malt but one to take your time over. The journey order changes and evolves over time, so nurse it. Im getting a bottle!
