The Importance of Geographic Wine Appellations: Hedonic Pricing of Burgundy Wines in the British Columbia Wine Market
Bibliographic record
Abstract
To examine the buying habits of British Columbia (BC) wine consumers and their appreciation of French wine attributes, we estimate a hedonic price function for Burgundy wines which comprise an array of different appellations, vintages, and alcohol levels. BC ranks among the top three wine‐consuming provinces in Canada and residents' wine preferences are likely linked to an emerging sophistication in tastes. This study uses weekly retail sales data and attributes of Burgundy wines reported by the BC Liquor Distribution Branch. The results confirm the collective reputation effects of the Burgundy wine region and show that the implicit values differ between white and red Burgundy wines with village designation and vintage having a relatively larger effect on white wine prices than in the case of red wines. Burgundy white wines, such as Aloxe‐Corton, Chassagne‐Montrachet Premier Cru, Meursault Premier Cru, and Chablis Grand Cru, were associated with larger price premia. Afin d'examiner les habitudes d'achat des consommateurs de vin de la Colombie−Britannique et leur appréciation des caractéristiques des vins français, nous avons estimé une fonction de prix hédoniste des vins de Bourgogne d'appellations, de millésimes et de degrés d'alcool variés. La Colombie−Britannique figure parmi les trois provinces canadiennes où l'on consomme le plus de vin, et les préférences des consommateurs de vin découlent probablement d'un raffinement des goûts. Dans la présente étude, nous avons utilisé les données des ventes au détail hebdomadaires et les caractéristiques des vins de Bourgogne fournies par la Société des alcools de la Colombie‐Britannique (BC Liquor Distribution Branch). Les résultats confirment les effets de la réputation de la région viticole de la Bourgogne et montrent que les valeurs implicites diffèrent entre les vins de Bourgogne blancs et rouges, et que l'appellation «village» et le millésime influent davantage sur les prix des vins blancs que sur ceux des vins rouges. Les prix des vins de Bourgogne blancs, tels que Aloxe‐Corton, Chassagne‐Montrachet Premier Cru, Meursault Premier Cru et Chablis Grand Cru, ont présenté des primes plus élevées.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
