WebThe propionic acid produced during propionic acid fermentation contributes to the distinctive flavor of Swiss cheese, for example. Several fermentation products are important commercially outside of the food industry. For example, chemical solvents such as acetone and butanol are produced during acetone-butanol-ethanol fermentation. WebOther familiar fermentation reactions include, ethanol fermentation (as in beer and bread) and propionic acid fermentation (it's what makes the holes in swiss cheese) and malolactic fermentation (it's what gives chardonnay is more mellow flavor, more conversion of malate - which tastes apple-y to lactate - which tastes creamy- the softer the wine).
