The effectiveness of these compounds and others is discussed as inhibitors of yeasts and bacteria in wine. Solubility generally limits the effectiveness of the individual esters, but combinations of the 6-, 7-, and 8-chain alcohol esters have additive effects and prevent yeast growth effectively. The heptyl ester also appears to be a potent antimicrobial agent against malo-lactic bacteria. Sensory tests indicate a slight bitterness associated with these compounds. ER -
