Purpose The complexity in determining the quality of a credence good like wine increases due to the lack of mandatory ingredient labeling. This has generated a significant information asymmetry in the wine market, leading consumers to delegate their purchase decisions to expert rankings and wine guides. This paper explores whether expert assessments reduce the information asymmetry caused by the absence of ingredient labeling in the wine market.Design/methodology/approach By employing analysis of variance (ANOVA) in a sample of 304 wines included in the Wine Guide of the Spanish Consumers Organization (OCU), this paper assesses the extent to which expert assessments based on sensory evaluations converge with the objective cues provided by laboratory analysis in wine quality evaluations.Findings Results reveal a mismatch between expert assessments and laboratory analyses. Chemical aspects such as SO2 levels or volatile acidity, sensorial factors such as intensity and persistence, and extrinsic variables such as the region of origin or wine type play an important role in the quality ranking of wines.Originality/value These findings call for the inclusion of objective intrinsic cues in expert sensory assessments to provide consumers reliable information about wines and to resolve the apparent dissonances in wine quality assessments.

El esfuerzo por cartografiar los límites de las periferias urbanas requiere de una necesaria discusión conceptual previa. El presente texto tiene como objetivo principal plantear, mediante una aproximación histórico-comparativa, una definición lo más precisa de Exurbia, un linde de la ciudad particularmente complejo y poliédrico. Complejo, porque su mapeo debe reflejar una hibridación de usos de suelo urbanos y rurales, así como un enorme abanico de tipologías edificatorias. Poliédrico, porque una correcta caracterización social y económica de las franjas exurbanas de la ciudad, resulta difícil de acotar a través de criterios estadísticos o censales simples. Por tanto, sintetizar las principales aportaciones de la literatura que, desde inicios del siglo XX, tratan de explicar dicha diversidad y multidimensionalidad, supone el segundo objetivo transversal al desarrollo del artículo.
