Table 5: Effect of wood format on the general aromatic composition of the distillate. All data are expressed in ug/L except where expressly indicated. Different letters within each row denote significant difference between the wines at \(p\) < 0.05 ([PERSON]’s post hoc test). *, **, *** and ns: differences significant at \(p\) < 0.05, 0.01, 0.001 and not significant, respectively. The main groups of compounds analyzed are highlighted in bold. Lightly toasted or untoasted wood significantly reduced the concentration of esters, both the ethyl esters of medium-chain fatty acids and the acetate of higher alcohols. Namely, in the case of ethyl hexanoate, the difference between the control thesis and the aged sample with lightly toasted wood was about -69%. Similar variations were also noted for ethyl octanoate (-69%) and ethyl decanoate (-43%) as well as long-chain fatty acid esters (ethyl myristate and ethyl palmitate) (Table 4). The content of acetate esters of higher alcohols underwent an even greater variation when comparing the control thesis and the theses treated with untoasted wood, up to 75% in the case of hexyl acetate.
