Microbiological Expertise

With our team of specialists and the latest relevant tools in microbiology, our laboratory is able to offer comprehensive expertise for the identification and counting of microorganisms, from the grape to the bottled wine.

Our team (including doctors and technicians in microbiology, engineers, chemists and winemakers) is at your disposal to respond to all of your microbiological problems.

SARCO offers both classical techniques of microbiology and recent biological genetic methods as well as tools for the determination of contaminants coming from microorganism spoilages.
