| dc.description.abstract | Sixty-one different fortified wines, from the Douro valley, inoculated with Lactobacillus hilgardii previously isolated from a spoiled fortified wine, were sampled progressively for 280 d. Samples were analysed for volatile acidity (acetic acid) and frozen for subsequent analysis where appropriate. After 280 d, 7/61 wines showed increases in volatile acidity of >0.5 g l-1 and were considered spoiled. Retrospective analysis of frozen samples of spoilage-positive wines showed that all had apparently undergone a malolactic conversion before the onset of heterolactic activity (acetate production). It is suggested that the monitoring of L-lactic acid might be a method of detecting activity of spoilage lactobacilli before the onset of spoilage. | por |
