In some countries
such as China and Mexico, the maximum limits for higher alcohols
in beverages have been established. For example, in China the
maximum higher alcohols (by iso-butanol and iso-amyl alcohol) in
distilled spirits and liqueur must be less than 3.33 g/L of pure
alcohol by the current related Chinese Standards. In Mexico, the
range of higher alcohols is from 0.2 g/L to 4 g/L of pure alcohol in
Tequila and some other Mexican spirits
