All the alcohol studied came from alcoholic fermentation,
except n-hexanol, formed at any stage preceding alcoholic fermentation
(harvest, transport, crushing and pressing of grapes)
(González-Álvarez et al., 2012). Therefore, yeast plays an important
role in higher alcohols synthesis. As we have written above,
depending on the type of fungicide treatment, the yeast population
can be affected. Oliva et al. (2007) analysed the influence on grape
yeast content and fermentation evolution, of the six fungicides
studied in this work. They showed that these six fungicides had
