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 five compounds with different levels among L76 and its derivatives.
