Microbial Stability

Chemical and microbial stability measures must be taken after fermentation but prior to bottle aging to protect the wine from contamination and subsequent off-aroma generation caused by microbial metabolism. Learn the most common methods for achieving
microbial stability, both during aging in the cellar and at packaging.
