Bacterial Fermentation

A vital part of the fermentation process of wine making and brewing is the type of bacteria used. Bacterial fermentation helps cut down the acid content of the wine. It also helps stabilise it and remove any other nutrients that could affect the wine making process. This helps sweeten the wine and you can use it to improve both its quality and aroma. At The Bottle Jar Store, we have a variety of bacterial products used for wine fermentation, especially for optimum Malolactic Fermentation (MLF). Please take a look at our selection below.

Why Should I Ferment My Wine?

Wine fermentation affects the properties of wine, including its aroma, body, smoothness, and taste. Malic acids in wine often lead to a more pungent and less pleasant flavour. Also, other compounds can give it a musty smell. Bacterial fermentation converts malic acid into lactic acid, which is smoother and sweeter. In addition, this process can help protect the wine from spoiling or losing quality over time, and prevents the risk of hazing which can lower its value. Finally, this process can add greater complexity to the wine and create new variations with different sensory traits.

What Happens When I Ferment Wine?

First, after the grapes have been turned into must, there is an initial process called alcoholic fermentation. Taking place in an oxygen and temperature controlled area, this process uses yeast to turn the must sugars into ethanol while the rest becomes wine. The second process involves using bacteria to soften the flavour and aroma and give it complexity. This is called bacterial fermentation and converts the strong-tasting malic acid into a milder one. Wine makers mainly use this process to make red wines, although some have used it to make white and rosé wines to create unique smells and tastes.

How Fermentation Affects Wine

Different processes are needed to produce different types of wine. For example, white wine needs an alcoholic fermentation process with a much lower temperature than red wine. Red wine needs to have a raised temperature during this process in order to take out the polyphenols found in the seeds and skins of the grapes. In addition, due to their complexity, red wines will need to ferment a second time using bacteria to improve their flavour and aroma. White wines often forego this process as it risks a loss of taste and scent, although some wine makers experiment with this process to create new types of wine.
