Is it worth the price?

KILCHOMAN 18 Years Old Family Collection Ex-Bourbon Barrels is an Islay single malt Scotch from the Kilchoman distillery, bottled at 18 years old. Tasters score it 5.0 out of 5 across 1 reviews. A single retailer lists it at €242.00, against a model fair price of around €237.44. That is 1.02× 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.
