A comparison of a plating method and a DNA-based method to identify the yeast present in a commercial fermentation

After using either a culture-based method or a DNA-based method to identify the yeasts growing in a wild fermetation, here the authors compare the two methods side by side.

The emphasis is on microorganisms we may think we are protected against -because they are unable to grow on a plate-, but that may actually be recovering from the SO2 treatment and getting ready to spoil our wines.
