A PROPOS DE LA FERMENTATION MALOLACTIQUE<\/h5>\n
Un peu d\u2019histoire<\/i><\/span><\/span><\/span><\/h5>\n
La fermentation malolactique est longtemps pass\u00e9e inaper\u00e7ue. Elle a \u00e9t\u00e9 observ\u00e9e pour la premi\u00e8re fois au <\/i><\/span><\/span><\/span>XIX<\/i><\/span><\/span><\/span>e<\/i><\/span><\/span><\/sup><\/span>\u00a0si\u00e8cle en Suisse et en Allemagne\u00a0: le microscope r\u00e9v\u00e9lait une augmentation de l’activit\u00e9 bact\u00e9rienne, suivie d’une augmentation de l’<\/i><\/span><\/span><\/span>acidit\u00e9 volatile<\/i><\/span><\/span><\/span><\/a>. La baisse d’acidit\u00e9, quant \u00e0 elle, \u00e9tait imput\u00e9e \u00e0 la pr\u00e9cipitation du <\/i><\/span><\/span><\/span>tartre<\/i><\/span><\/span><\/span><\/a>. La \u00ab\u00a0malo\u00a0\u00bb semblait donc d\u00e9grader le vin, et on essayait \u00e0 tout prix de l’\u00e9viter. Pasteur disait\u00a0: \u00ab\u00a0les levures font le vin et les bact\u00e9ries le d\u00e9truisent\u00a0\u00bb.<\/i><\/span><\/span><\/span><\/span><\/span><\/h5>\n

Cette fermentation est ma\u00eetris\u00e9e depuis les ann\u00e9es 1963-1972.
