The rate of MLF (Ml×100/M+Ml) was calculated. M; malic acid: Ml; mol. malic acid/mol. lactic acid × lactic acid in wine. The correlation coefficient (γ) between evaluation score and MLF-rate was-0.0347 in white wines (n=45), and 0.6717 in red wines (n=31). Apparently, MLF tends to taste high evaluation in red wines.
