The influence of irrigation and plantation density on the methoxypyrazine content in musts and wines has been studied. Samples were monitored throughout grape ripening and wine-making. 3-Isobutyl-2-methoxypyrazine, 3-sec-butyl-2-methoxypyrazine and 3-isopropyl-2-methoxypyrazine were identified and quantified. Samples from irrigated vines had significantly higher average contents of 3-isobutyl-2methoxypyrazine than samples from non-irrigated plants. Average levels of this compound were also higher in samples from vines with the higher plantation density. (c) 2005 Society of Chemical Industry.
