Aguardente, sugar cane

For the sugar-cane and maize aguardentes (C4 plants), ( H/ H)i values are in the range from 111.7 to 113.6 ppm. Therefore, a satisfactory discrimination (approximately 10 ppm) between C3 and C4 aguardentes has been observed. 

The results have shown that a great number of commercial aguardentes have undergone for some adulteration process, possibly by using the sugar-cane aguardentes, which have a low cost involved in its manufacture process. 

SNIF-NMR method and chemometric analysis applied to h NMR spectra can distinguish aguardentes produced from plants with different biosynthetic origin as C3 (grape, banana, cassava and honey), C4 (sugar-cane and maize) and CAM (pineapple). 

Cachaqa and aguardente de cana are the most consumed distilled spirits in Brazil exclusively made from cane-sugar juice. Sugar and caramel maybe added for colour adjustment. The total content of congeners is between 200 and 650 mg 0.1 L p.e. Like other spirits, the flavour of cacha a is mainly characterised by the presence of fermentation by-products such as higher alcohols, esters, carboxylic acids, and carbonyl compounds [41-43].
