Is it worth the price?

KILCHOMAN Rockside 11 Years Old is an Islay single malt Scotch from the Kilchoman distillery, bottled at 11 years old. Tasters score it 4.8 out of 5 across 8 reviews. It is tracked at 3 retailers, ranging from €62.50 to €64.90, while the valuation model estimates a fair price of around €77.60. That is 0.82× the model estimate — almost exactly what its age, strength and house predict, with no meaningful brand premium. The estimate is fitted on age, bottling strength and the distillery's other prices; community ratings add no measurable signal to it, so this is not a quality judgement. Typical error is around ±65%, so read the verdict as indicative and trust it most at the extremes. It is one of 14 Kilchoman bottlings priced here; the others are compared below.
