Accepted 5 December, 2012 Alcoholic beverages are produced practically in every country in the world representing a significant percentage of the economy. Mead is one of the oldest beverages and it is easily obtained by the fermentation of a mixture of honey and water. However, it is still less studied compared to other beverages and does not have industrialized production. It is prepared as a handmade product. The origin of the honey used to formulate the mead creates differences on the final product characteristics. In this study, fermentation occurred at temperatures of about 22.1 ± 0.4°C after a previous pasteurization and inoculation. Saccharomyces cerevisiae (K1-LALVIN 1116) was used to produce the mead that was prepared in order to obtain dry mead by mixing 200 g L-1 of honey in water. For better -1 -1 results inorganic salts were used [(NH4)2SO4: 0.2 g L , (NH4)2HPO4: 0.02 g L ]. The results at the end of the process were a mead with: 12.5 ± 0.4°GL; pH 3.33; low amounts of high alcohols and methanol and great quantity of esters, that provide a nailing flavor to the beverage.
