You may wish to stop the fermentation early and leave a bit of residual sugar in your wine. Just like people, yeast are more active when they are warm. Each wine's rate of fermentation will be different so you will need to check it throughout the fermentation to monitor the progress. To browse our extensive selection of wine yeast, click here!

In the end there is no "correct" sugar level for your wine, it just comes down to your personal preference.

This first step usually lasts between 10 and 15 days and requires constant control.
Although the fermentation usually stops by itself when the volume of sugars falls and the microorganisms die due to lack of food, it is safer to control it by means of the temperature, since by increasing it or reducing it we can render the yeasts inactive.
This is the second fermentation and it aims to reduce the acidity, turning the malic acid of the fruit into lactic acid. This process results in some loss of colour and an increase in volatile acidity. This process is recommended for wines that have a lot of flavour per se , because with a white wine, for example, it would result in a wine without flavour or aroma.
As you can guess, each type of fermentation results in a type of wine. As a general rule, white wines requires a lower temperature in the first fermentation and this rises until we get to red wine, which requires a higher temperature in order to extract the polyphenols present in the skin and seeds of the grapes.
Malolactic fermentation is typical of red wines which, as well as a more complex production process, have a greater aromatic complexity , which is complemented by the oak of the barrels in the case of aged wines. If you find the whole process remarkable, you will be surprised to learn that wine fermentation is a process that is almost as old as the history of mankind.
