In the fermentation process of tequila, the type of yeast strain, the
temperature (30 or 35 degrees C) and the C/N ratio (62 or 188) had a s
ignificant influence in the level of higher alcohols produced. On the
contrary, other parameters like nitrogen source [urea or (NH4)(2)SO4]
and inoculum amount (5% or 10%), have little or no influence on the pr
oduction of the compounds responsible for some of the organoleptic pro
perties of tequila.
