In recent years, the interest on craft beer has been increasingly growing. In this work, sensory traits of five Italian artisanal beers were explored by a trained panel, through different sensory analysis methods: Quantitative Descriptive Analysis (QDA) and a sensory dynamic method, Temporal Dominance of Sensations (TDS). The sensory profiles obtained through these methods were compared to the description given by an expert beer taster. The trained panel (n = 12) evaluated five Tuscan beers, manufactured in Maremma area, Tuscany region, first through QDA. Twenty-eight sensory properties (visual, tactile, flavor and aromatic traits) were evaluated through a nine point scale. The descriptive profile was enriched by a dynamic sensory evaluation method, TDS. TDS was used by panelists to obtain a “real-time” flavor profile of the craft beers. During tasting, TDS provided information on the most striking flavor traits chosen among: floral, honey, roasted, chestnut, spicy, fruity, hoppy, and malty, of each beer. A PCA analysis showed the importance of the flavor attributes for beer profile compared to the expert taster description. Results highlighted the main traits of each beer and showed the validity of different profile methods. The interesting outcomes both provided useful profile patterns for brewers aiming at targeting specific segments of beer market and supported the development of interesting instruments for beer sensory analysis.
