Optimise wine yeast nutrition with Stimula^TM

Winemakers face many challenges associated with climate changes. Better quality nutrients are required to overcome those issues. Higher sugars and pHs can lead to a higher level of contaminants, and specific nutrients can assist to manage the alcoholic fermentation (AF). Research has shown that a well-balanced organic nutrition can increase yeast viability and vitality, improves wine aromatic expression due to optimized assimilation. The timing of addition of key nutrients will optimize varietal aromatics expression. To read more, please click on the link below. UI Stimula Cabernet - ENG (002)

Wine Yeast Rehydration

Proper wine yeast  rehydration is necessary because grape must is a very hostile environment with its low acidity, high sugar and osmotic pressure, and nutrients or micronutrients limitations is a big challenge for any yeast to conduct AF. Quality, fault free wine is related to a successful AF, and that comes with taking good care of your dry wine yeast.  The Under Investigation explains why and how, and how rehydrating your yeast is key, and especially with a protector like Go-Ferm Protect Evolution.

Wine yeasts are able to produce volatile aroma compounds from precursors found in the grape musts. Despite this ability, the wine yeast needs an adapted nutrition management (type of nutrient and timing of addition) that will maximize this secondary metabolism. Work done in collaboration with INRA (Montpellier, France) has shown that the type of nutrient, and the timing of addition during alcoholic fermentation has an important impact on the production of fermentative aroma compounds. Stimula Chardonnay™ has been shown to maximize specific aroma compounds in Chardonnay wines UI Stimula Chardonnay 2019 ENG USA  

Stimula Chardonnay^TM

Stimula^TM 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 Chardonnay^TM is particular rich in biotin, B6 vitamins, magnesium and zinc which optimize the volatile ester biosynthesis by the yeast.  Use Stimula Chardonnay^TM at 40 g/hl at the first ¹/₃ into the alcoholic fermentation to enhance the biosynthesis of aroma compounds and support the bioconversion of precursors to volatile esters until the end of the fermentation.   The addition of this new product makes a significant impact on the flavour profile of the wine.  Keep on reading our Nutrient and Protector Under Investigation edition no. 2 for more details.
