Balanced nutrition for a healthy alcoholic fermentationNitrogen is an essential nutrient for smooth alcoholic fermentation (AF). Numerous studies have shown that nitrogen has a positive impact on the growth and fermentation activity of yeast (Bell et al. 1979, Ough and Lee 1981, Bezenger and Navarro 1987). Deficiencies in yeast-available nitrogen (YAN) in the must significantly increase the risk of sluggish or […]

Safe alcoholic fermentation: Providing complete nutrition for the yeastTo protect yeasts when introducing them into must with high risk factors. • Balanced nutrition promotes yeast growth and optimizes the sensory impact of fermentation. • Simply providing ammonia nitrogen and thiamine is not always enough for successful fermentation Lallemand Practical Vinification Guide #3 –

Sculpting the aromatic profile of wine through diacetyl management In addition to carrying out the bio-deacidification of wine, malolactic (ML) bacteria influence aroma and flavour through various mechanisms, including the production of volatile grape- and yeast derived metabolites. In wine, one of those volatile compounds – diacetyl – has important stylistic implications. This diketone, also known as 2,3-butanedione, is associated with the “buttery” character […]

Wine Bacteria – contributor to wine stylesThe evidence is stronger than ever. Malolactic bacteria are important tools to influence the sensory profiles of wines. It has been long known that malolactic bacteria (ML) are essential to reduce the acidity of wine through malolactic fermentation. But now, our on-going research is showing their sensory potential as well. Whether a Chardonnay is more […]

Bacteria rehydrationLallemand offers two popular formats of freeze-dried bacteria cultures: The MBR® form of malolactic bacteria represents a Lallemand acclimatization process that subjects the bacteria cells to various biophysical stresses, making them better able to withstand the rigors of direct addition to wine. The conditioned MBR® bacteria that survive are robust and possess the ability to […]

Rosé FermentationIn 2006, the world production of rosé wines was estimated at 21.5 million hL – 9% of the total world production of wine (Aigrain 2009). Production has been increasing for several years. In the United Kingdom, for example the main sellers are rosé wines from the United States – almost half of the total wines […]
