Is it worth the price?

BUNNAHABHAIN Toiteach A Dha is an Islay single malt Scotch from the Bunnahabhain distillery, released without an age statement. Tasters score it 4.9 out of 5 across 21 reviews. It is tracked at 3 retailers, ranging from €44.90 to €61.90, while the valuation model estimates a fair price of around €103.38. That is 0.52× 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. It is one of 13 Bunnahabhain bottlings priced here; the others are compared below.

Methodology estimate

The deterministic model from methodology.md: production cost per litre × bottle size, plus maturation cost per year, plus a cask premium, times an ABV factor — then multiplied by a quality grade summed across six 0–3 axes.

mild premium

The two models disagree sharply here. The deal-score regression learns from peer prices that age and brand command €103.38 (0.52× the listed price), while the cost-and-quality methodology floors the bottle at €30.64 (1.75×). The gap is the brand premium the market pays beyond what materials, maturation and bottling integrity alone can justify.
