Spraying ethanol (5% v/v in water)onto grape clusters at mid-veraison led to a 30 % drop in the malic acid concentration at harvest. As a consequence, tritable acidity also dropped by 10 %. The concentration of tartaric acide did not change significantly. The mode of action of ethanol on malic acid metabolism is discussed.
