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.

brand premium

The two models disagree sharply here. The deal-score regression learns from peer prices that age and brand command €467.94 (1.12× the listed price), while the cost-and-quality methodology floors the bottle at €151.95 (3.45×). The gap is the brand premium the market pays beyond what materials, maturation and bottling integrity alone can justify.
