Is it worth the price?

MORTLACH 11 Years Old 2014 1st Fill Oloroso 100 Proof #73 Signatory Vintage is a Speyside single malt Scotch from the Mortlach distillery, bottled at 11 years old. Tasters score it 4.3 out of 5 across 3 reviews. A single retailer lists it at €64.90, against a model fair price of around €110.34. That is 0.59× the model estimate — well below what its age, strength and house predict, and one of the clearer value picks in the data. 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. Of the 3 Mortlach bottlings priced here, this is the strongest value.
