Yeast nutrition and aroma enhancement
Yeast Nutrition: Optimising Fermentation Performance and Aroma
Yeast nutrition is a critical lever by which brewers can manipulate fermentation kinetics, attenuation, flavour stability and aroma expression. Yeast lacking proper nutrition can lead to sluggish fermentations, stuck ferments, off-flavours (e.g. H₂S, volatile sulphur compounds), or loss of thiols/esters. Meanwhile, over-feeding or imbalanced nutrition can also lead to unwanted by-product formation (e.g. diacetyl, higher alcohols).
Optimising yeast nutrition gives the brewer practical advantages that are reflected in the final product that reaches the consumer. In this article, we dive into the theory, key nutrient classes, practical dosing strategies, and how modern, balanced nutrient blends such as AEB’s FERMOPLUS® range can support these goals
Introducing our newest nutrient: Fermoplus AromaGlow
FERMOPLUS® AromaGlow increases the yeast’s production of terpenes, esters and thiols, enhancing the aromatic complexity and intensity of the beer. Its yeast autolysates improve mouthfeel providing body and volume. Additionally, it reduces ageing compounds and can reduce the dry hopping rates required, offering brewers both economic advantages and quality improvements.
Many key biological processes play pivotal roles in aroma compound production in fermentation, three of them are the Ehrlich pathway, esterification and the IRC7 gene pathway. In this article, we’ll explore each of them in-depth and how FERMOPLUS® AromaGlow optimizes them and other quality aspects of beer. In this article, we’ll explore each of them in-depth and how FERMOPLUS® AromaGlow optimizes them.
FERMOPLUS PerfectBrew-Zn
The key advantage of using yeast-derived zinc, such as that found in FERMOPLUS® PerfectBrew-Zn, over zinc sulphate or other zinc salts lies in its superior bioavailability and ease of assimilation by yeast.
Fermoplus range
Fermoplus Fragrance is a new-generation yeast nutrient with a specific amino acid composition that promotes intense esters and thiols in beer that complement your chosen hops. It also provides the right nutrition to your yeast for a complete and healthy ferment.
