Finally, a multivariate analysis of variance was carried on red
Grenache wines with nitrogen contents and strain as main effects,
on wines made with L76 and derivatives and separately on L78 and
its derivative. Results are shown in Table 3. Only levels of three
compounds, ethyl 9-decenoate in wines made with L76 and its
derivatives and 2 þ 3-methyl butanol and ethyl decanoate in wines
made with L78 and its derivative, were different depending on
nitrogen contents. The fusel alcohol increased with nitrogen and
the esters decreased. Tukey test shows fi ve compounds with
different levels among L76 and its derivatives.
