Estudo de variações nos parâmetros de qualidade de uma cerveja artesanal, do tipo lager ao longo do tempo de prateleira (Shelf-life)

Abstract

The growth of craft beers in Brazil over the past 6 years has been exponential, leading to an undeniable increase in the supply and demand for these products, and consequently, an increase in competitiveness and quality of these beers. Several studies are already comparing the differences in craft beers in terms of quality, sensory aspects, durability, and stability, compared to commercial beers. Many of these studies demonstrate that craft beers have good stability and, therefore, a good shelf life, although shorter than pasteurized and filtered commercial beers. During the research period, various parameters were analyzed, such as alcohol content, specific gravity, pH, color, and turbidity, in order to discuss the variables that can affect the stability of these parameters, whether during production or storage. Finally, it will be determined if the beer meets the quality and legal standards defined by law at the end of the analysis period, offering an estimation of the shelf life for the beer studied in this work.
