Inoculating with yeast to acidify

A non-Saccharomyces yeast, Laktia,  can naturally acidify white and red musts by converting a small amount of sugar into lactic acid at the start of alcoholic fermentation. This is a new way to acidify wine. The article is published with the permission of La Vigne TAP-ANG Levure


OPTIWHITE® en OPTIMUMWHITETM is spesifieke geïnaktiveerde gis ryk aan werklik beskikbare glutatioon en poli-sakkariede. Die gebruik van hierdie produkte met die aanvang van die alkoholiese fermentasie beskerm wyn aromas, kleur en ondersteun ook goeie mondgevoel vir baie lang tydperke – selfs meer as  ʼn jaar na bottelering.


Stimula Chardonnay

To enhance the flavour profile of your Chardonnay

Organic nutrients are making a significant contribution to final wine aroma profile of your Chardonnay.  However if you are also using DAP, be careful for not adding too much of a “good” thing.  Take time to read the attached article for more information on this very relevant topic.   StimulaTM is a new range of 100% yeast autolysate formulated to supply the optimal levels of amino acids, sterols, vitamins and minerals known to optimize the aromatic metabolism of the yeast.  Stimula ChardonnayTM is particular rich in biotin, B6 vitamins, magnesium and zinc which optimize the volatile ester biosynthesis by the yeast.  Use Stimula ChardonnayTM at 40 g/hl at the first 1/3 of alcoholic fermentation to enhance the biosynthesis of aroma compounds and support the bioconversion of precursors to volatile esters until the end of the fermentation.
