Stimula Chardonnay™

Stimula™ 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™ is particular rich in biotin, B6 vitamins, magnesium and zinc which optimize the volatile ester biosynthesis by the yeast. Use Stimula Chardonnay™ 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.

Stimula Sauvignon Blanc™

Stimula™ is a new range of nutrients of 100% yeast autolysate formulated to supply the optimal levels of amino acids, sterols, vitamins and minerals to optimise the aromatic metabolism of yeast. Stimula Sauvignon Blanc is particularly rich in panthotenate, thiamine, folic acid, zinc and manganese in order to optimise the uptake of 4MMP and 3MH precursors and their subsequent bioconversion to volatile thiols by yeast. Use Stimula™ Sauvignon Blanc™ at 40g/hl at the start of fermentation and optimise your thiols.
