Objective. Estimate the price and income elasticities of the demand for beer in Mexico. Materials and methods. Monthly series on beer sales and prices from 2007 to 2019 were used. Long-term elasticity was estimated using ordinary least squares (OLS). Short-term elasticity was estimated using a dynamic ordinary least squares (DOLS) model. Results. The price elasticity was in the long term of -1.40 (95%CI: -2.53 to -0.27) and -1.31 (95%CI: -2.46 to -0.15) in the short term. The income elasticity of demand in the long and short term was estimated at 0.86 (95%CI: 0.44-1.29 and 0.93 (95%CI: 0.51-1.34), respectively. Conclusions. The findings of this study suggest that fiscal policies may have a positive impact on the health of the population by reducing beer consumption. [ABSTRACT FROM AUTHOR]

Beer production depends on three essential components: wort, hops, and yeast. Our objective was to isolate wild yeasts suitable for the brewing process. We isolate 64 yeast strains from different desert flowers and fruits from Nuevo León and Durango. Molecular results obtained with RFLP and nucleotide sequence of the intergenic region (ITS) of the 18 S ribosomal RNA, showed that strains named as FI22- 1A, FI22-2F, FI25-2F and FI31-1A belong to the genus Saccharomyces, while another, the UV10-1A belongs to Torulaspora. Flow cytometry results demonstrate that Saccharomyces strains are diploid and Torulaspora is triploid. The organoleptic data of craft beer with these new strains showed desirable characteristics for the fermentation of brewer's wort. [ABSTRACT FROM AUTHOR]
