Abstract:
Chemical and sensory properties of Torrontés Riojano sparkling wines, prepared using second fermentation with Saccharomyces strains EC1118, bayanus C12 and IFI473I, were explored. All sparkling wines showed high levels of several volatile ethyl esters and terpenes associated to fruity and floral aromas. The sensory profiles showed significant differences for the floral aroma descriptor among EC1118, bayanus C12 and IFI473I and for bubble persistence for strain bayanus C12. Our results suggest that the sensory properties of these sparkling wines could be dependent on the chemical and organoleptic properties of the base wine more than the yeast strain used for second fermentation.

Fermentation
Fermentation is a type of metabolic process that occurs in the absence of oxygen, where organic molecules such as glucose are broken down to produce energy. During this process, the...

Carbonation Shrinkage
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...
Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
