That creamy, buttery aroma you sometimes find in a bottle of Chardonnay or other wines is thanks largely to a compound called diacetyl. It's the star player released during malolactic fermentation (MLF), and whether a winemaker wants to emphasize or eliminate it is one of the biggest stylistic...

Malolactic Fermentation Feasibility: Factors Affecting Ease of MLF There are several factors that influence malolactic fermentation (MLF). This includes obvious factors like alcohol, pH, and SO2 but also includes less obvious factors like alcoholic fermentation difficulty, yeast nutritional...

Spontaneous malolactic fermentation can be risky business for winemakers as it offers very little control over the microflora in wine. Some concerns include: Variable speed of MLF VA production Biogenic amines (e.g. histamine) Risk of MLF in the bottle (CO2!!) Opportunity for spoilage microbes like...

During malolactic fermentation (MLF), Oenococcus oeni, the primary bacteria involved in this process preferentially consumes malic acid. However, as malic acid becomes depleted towards the end of MLF, the cells start consuming citric acid, leading to the production of diacetyl. Interestingly, once...

Need help selecting malolactic bacteria that is right for your wine? The right bacteria for your wine depends heavily on your wine conditions. The most important parameters are: pH Total SO2 Alcohol Temperature of wine undergoing MLF Extremes in one or more of these properties can have a...
