Use Fermaid K+ to compensate must deficience in nitrogen and micronutrients

It's unique. There is nothing else like it!

FERMAIDTM  K+ is a blended complex yeast nutrient suitable for use in the alcoholic fermentation of grape must. Developed by the technical oenology group from Lallemand. Propper use of FERMAIDTM  K+ helps compensate must deficiency in nitrogen & micronutrients and drastically reduces the occurrence of sluggish and stuck fermentations. Fermaid K+ marketing

Enhance aromatic expressions in your wine

Beyond looking at nutrition or completing #fermentation, Lallemand Oenology has developed a range of #nutrients which aim at optimizing the aromatic expression of your #wines, by nourishing the #yeast and stimulating the yeast cell functions involved in aroma metabolism: the #Stimula range. 🔬 Each of the 4 products already available in the range are based on 4 wine yeast strains optimized with amino acids, vitamins and minerals to target specific varietals, like     #Sauvignon blanc,   #Chardonnay,   #Cabernet or #Syrah. 🍷  Together with our knowledge of yeast metabolism and with recent results from our research partners, we have defined the optimal moment to add our Stimula solutions, which differs from one product to the other and has been specifically finetuned to expand the aromatic complexity and the expression of your wines. ➡️  Jason Amos, one of the Area Managers for #lallemandoenology, tells you all about the Stimula range: https://lnkd.in/dQiPYfRu

The crucial step for a successful alcoholic fermentation in wine – Wine Yeast Rehydration

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.

CUSTOM NUTRITION FOR SPECIFIC WINE YEASTS IN SAUVIGNON BLANC

Sauvignon Blanc

In an increasingly competitive market, optimizing the quality of wines, especially the sensory properties, is a major challenge for winemakers. Wine aroma is one of the principal attributes determining wine consumers’ preferences. The importance of nutrients such as nitrogen or lipids in alcoholic fermentation is well known in the wine industry. Indeed, to assure a complete fermentation with a regular kinetic, winemakers have to ensure that musts have adequate nutritional, physical, and chemical conditions for optimum yeast development. More recently, lipid content, temperature, as well as nitrogen and other micronutrients have been shown to have a great impact on a large number of flavour compounds biosynthesized by wine yeast during alcoholic fermentation. The interactions between nitrogen and other key nutrients such as lipids and vitamins and their influences on yeast viability and yeast fermentative capacities will be explain in the first part of this article. The second part will aim at demonstrating the importance of nutrients and micronutrients in yeast aroma metabolism as well as yeast’s ability to synthesize aromas and especially to reveal varietal aromas in Sauvignon Blanc winemaking.

ESL 2019 : Biological tools in winemaking adapting to a changing environment

The proceedings from the 2019 Entretiens Scientifiques Lallemand held in Weisbaden Germany are now available. the 2019 international meeting focused on different strategies to overcome some of the issues related to climate change. From the vineyards with Lalvigne foliar sprays to managing acidity with non-Saccharomyces yeast, to nutrition and oxidation management. Special guests from the Geisenheim Institute , Prof Manfred Grossman and Prof J. Wendland presented the latest work from the Institute. The Entretiens had the privilege of hosting Prof Monika Christmann from Geisenheim University and the OIV 1st Vice-President as the key note speaker.   ESL 2019 eversion
