Abstract: Free sulfur dioxide (SO2) is a key parameter monitored throughout the winemaking process and at bottling to ensure wine is adequately protected from enzymatic and chemical oxidative effects and microbial spoilage. The aim of this study was 1) to benchmark...
One of the keys to a successful fermentation is removing any native wild yeast and bacteria from the must prior to adding your special winemaking yeast. Wild yeast and bacteria can consume sugar from grape juice just as easily as your special yeast can, but generally produce some pretty...

An Introduction to SO2 Management
If we want to make high quality wines, then one of the most important things we as winemakers need to learn is how to effectively manage the sulfite levels in our wines. When done correctly, maintaining the proper amount of sulfites in a wine protects it...
Types of SO2
We recommend SO2 in 2 specific forms for addition to your wine, Potassium Metabisulfite (most common) and Efferbaktol (our favorite). Potassium Metabisulfite is often shortened to “meta” “SO2” “Sulfite”, and comes in a white powder...
