Fermentation optimisation - Alcoholic fermentation activators

VITISTART

For highly scrubbed white or rosé musts

A complete activator which provides all the elements required for optimum fermentation. Supplies available nitrogen to multiply yeasts. Supplies available nitrogen to multiply yeasts. The inactivated yeasts encourage detoxification of the medium and provide vitamins, trace elements and sterols. The cellulose increases the turbidity and acts as a yeast support. The thiamine stimulates growth rate.

ACTIVIT

For musts with significant deficiencies and fermentation halts

ACTIVIT is made up of Diammonium phosphate, inactivated yeasts and thiamine. It therefore supplies available nitrogen, vitamins and acts as a detoxificant. The proportions of each components are perfectly suited to the treatment of difficult musts with significant deficiencies.

THIAMINE

To make it easier for yeasts to grow

THIAMIN (or vitamin B1) acts on yeast growths, increasing the population and prolonging the duration of their activity. To do so, it acts on the carbohydrate metabolism when the decarboxylation of ketonic acids into aldehydes takes place.

ACTIVIT NAT

For the co-inoculation and must with low deficiencies

ACTIVIT NAT is a fermentation activator made up exclusively of inactivated yeasts. This 100% natural activator provides amino acids, small peptides and stress resistance factors that are absorbed by the yeasts throughout alcoholic fermentation.ACTIVIT NAT provides balanced alcoholic fermentation (contrary to ammonium salts) and a well-defined end to alcoholic fermentation.ACTIVIT NAT also contributes to the organoleptic quality of the wine and reduces risks of the production sulphur compounds.

EXTRA PM

Fermentation activator specifically intended for bottle fermentation

EXTRA PM guarantees optimal yeast activity during Tradition, Charmat, ancestral bottle fermentation.

ACTIVIT O

For top quality fermentation

ACTIVIT O is a 100% organic balanced nutrient, essential for grapes to express their aromatic potential.

FOSFOVIT

A mineral nitrogen activator for promoting yeast growth

FOSFOVIT provides a nitrogenous supplement to boost alcoholic fermentation in nitrogen-poor media. We recommend its use one third of the way through alcoholic fermentation or with secondary fermentation.Since it also contains thiamine (0.15%), FOSFOVIT makes a strong yeast growth possible but avoids some of the disadvantages connected with the use of ammonium sulphate (a potential source of SO2 and unacceptable for organic winemaking).
