The brewing market undergoes a revolution directing to production on a homemade scale rather than an industrial scale, due to the expectations of consumers searching high quality and new flavor of the final product. In order to produce a light beer with respect to the extract and alcohol content and different flavor, several ginger addition tests were carried out in the production process. The most viable result was obtained with addition of 2 g L-1 of ginger flakes in natura at maturation. The artisanal brewed beer of ginger was produced in laboratory scale, to allow its physical-chemical analysis and sensorial analysis. In parallel, others twenty-eight samples of Pilsen beer were analyzed for comparative purposes in relation to physico-chemical aspects. According to the result of the sensorial test, the overall acceptability index was 92% as also as individual attributes evaluated were also above 70%. The artisanal beer added with ginger showed characteristics closer to the "Beer" samples than the "Pure malt" samples, according to classification in relation to the malt content, by means of chemometric analyzes (PCA and HCA). This discrimination between groups was due to alcohol, real degree of fermentation (RDF), apparent degree of fermentation (ADF), potassium, calories and magnesium. The final product had a low alcohol content (3.40 oGL), low energy (115.44 KJ 100 mL-1) and reduced extract (7.81 oPlato). Despite the more pronounced bitterness (21.55 B. U.), the acceptability index forbitterness remained above 70%, with spicy and aromatic flavor. |
