How to Use a Hydrometer for Winemaking (OldManStino)

In this three-minute video, we discuss how to properly use a hydrometer, the science behind how it works, and what some of the common scales listed on the hydrometer are (Specific Gravity, Potential Alcohol, and the Brix scale).


Malolactic Chromatography Testing (MoreWine!)

Malolactic fermentation (MLF) is a winemaking process involving a special bacterial strain that metabolizes the malic acid naturally found in grapes into lactic acid. Lactic acid is a weaker acid than malic acid so the effect of this conversion is a decrease in the wine’s acidity along with a corresponding raise in the wine’s pH. As an additional benefit, the bacteria also add mouthfeel and complexity to the wine.
