CY3079: For Classic White Burgundy Yet another one of my favorite innocuated yeasts, the CY3079 is a great Chardonnay favorite if you want the wine press to talk about the exotic fruits in your wine. Here's the description from the manufacturer: CY3079 was selected by the BIVB with the objective of finding a strain that would complement typical white Burgundy styles. CY3079 is a steady, slow fermenter even at cold temperatures (13°C). This strain benefits from using GO-FERM and Fermaid K. When properly fed, CY3079 has good alcohol tolerance (up to 15%) and is a low producer of VA and H2S. It is recommended for barrel fermented Chardonnay and sur lie aging. Chardonnays produced with CY3079 have rich, full mouthfeel and are characterized by aromas of fresh butter, almond, honey, white flowers and pineapple. Of course, this leads to the next question: what is Go-Ferm and Fermaid K. Here are the answers: GO-FERM Go-FERM is a completely original yeast nutrient researched and developed by Lallemand (patent pending). It is 100% biological specific inactive yeast produced through a unique yeast biomass process that is fine-tuned to obtain high levels of certain essential vitamins, minerals and amino acids that yeast requires for a healthy fermentation. The GO-FERM approach is to provide bioavailable micronutrients in the rehydration water instead of the traditional method of adding micronutrients to the must. By adding the micronutrients directly to the targeted yeast in a balanced concentration, they are more easily used by the yeast. This direct contact protects against the chelation of key minerals by inorganic anions, organic acids, polyphenols and polysaccharides present in the must. It also prevents essential vitamins from being rapidly taken up by wild microflora or inactivated by SO2 before the inoculated yeast can take advantage of these essential elements. The use of Go-Ferm results in significantly better overall health of yeast cells throughout the fermentation, affecting fermentation kinetics and resulting in a cleaner aromatic profile. This is especially evident when Go-Ferm is used in high maturity grape musts to avoid sluggish fermentation finishes. Fermaid K Fermaid K is a complete autolysed yeast based nutrient containing ammonia salts, amino acids, sterols, unsaturated fatty acids, vitamins, magnesium and pantothenic acid. At 2#/1,000 gallons (25g/hl), Fermaid K provides approximately 25mgN/l of YANC. It is recommended to add Fermaid K at 1/3 sugar depletion under nitrogen limiting conditions. |
