The product is a mix of inactive yeast cell walls, nitrogen, vitamins and trace elements. According to the supplier, the product removes toxic fatty acids through the inactive yeast cells and provides nutrients for yeast cell divi- sion and nitrogen. abmna.com ERBSLÖH GROUP Developed through the non-GMO process of "protoplast fusion," the new X-series of hy- brid yeasts by Erbslöh are a combination of Saccharomyces cerevisiae and a subspecies of bayanus. The new yeasts are described by the supplier as "powerfully fermenting with high tolerance of alcohol to enhance fruity thiols and exotic aromas." The yeasts are rec- ommended for Sauvignon Blanc, Chardon- nay, Chenin Blanc and other aromatic whites as well as rosé wines. erbsloeh.com, winerystuff.com AEB Fermoplus Tropical by AEB is a yeast nutri- ent to boost the production of tropical aro- mas. The product is derived from yeast cell walls and is rich with the amino acid pre- cursors. AEB reports the nutrient is loaded with leucine, phenylalanine, isoleucine and valine, which are linked to the production of aromas of ripe fruits, banana, pineapple and flowers. aebusa.com FERMENTIS Safoeno HD S135 yeast is a hybrid designed to incorporate the strains' best characteris- tics for polyphenols and persistence through difficult fermentation conditions. According to the supplier Fermentis, the yeast provides for quick fermentations and offers high alcohol and temperature tolerance with good fructose as- similation and low nitro- gen requirements. The yeast is recommended for red wines that are fruit-forward with a smooth profile. fermentis.com, atpgroup.com BSG BSG introduced two new yeasts for grapes picked later in harvest, VP5 and Premium Zinfandel, which the supplier reports also work well as co-fermentors. VP5 is an iso- late from the province of Valpolicella in Italy and is suited for producing "young, fresh red wines enhancing fragrant aro- mas." Premium Zinfandel is an isolate from Primitivo de Manduria in Italy and is "highly resistant to both high osmotic con- ditions and tem- perature stress." The supplier also notes the Zinfandel yeast can finish in stressful conditions with "significantly" lower volatile acid- ity and low sulfur dioxide. bsgwine.com
