Quality wine production depends on maintaining proper microbiological control during the transformation of grape juice into wine and its conservation. Our research provides microbiological techniques that allow winemakers to reduce microbial products, which can cause negative effects—such as headaches—to wine consumers, thus increasing the percentage of consumers able to take advantage of the health benefits related to moderate wine consumption.

2007

It`s no surprise that severely diseased grapes make poor wine. However, we found that even trace levels of powdery mildew set in motion a sequence of events that results in severely downgraded and wine that could not be sold. The damage is not due to the powdery mildew itself, but to how it shifts the naturally occurring (and normally beneficial) microbial community on grape berries towards one that produces foul flavors and odors during winemaking.
