This study verified the effect of the spontaneous fermentation/natural ferment (NF) on the chemo-sensory quality of cachaça, comparing to the commercial ferment (CF). The effect of ageing (maturation) was also analysed in the beverage. Microbiological analysis (plating on selective media for total/wild yeast and bacteria counting) and physico-chemical analysis (pH, acidity and soluble solids) were performed in the samples of the must and the ferment collected during three cycles of fermentation in a semi-industrial scale. Samples of cachaça were stored in 5-L oak containers for 45 days, subsequently analyzing the physico-chemical characteristics (pH, acidity, alcohol content, copper and secondary compounds) and sensory acceptability (aroma, flavour,... |
