Which of the following flavors is produced by yeast during fermentation?

The flavor associated with clove is produced by certain yeast strains during fermentation, particularly in the context of brewing beer. This flavor comes primarily from phenolic compounds like 4-vinyl guaiacol, which is created by yeast, especially when fermentation occurs at higher temperatures. This characteristic is commonly found in specific beer styles, such as hefeweizens and other wheat beers, which are known for their fruity and spicy notes.

The other flavors listed—coffee, creamed corn, and herbal—are typically not produced by yeast during fermentation. Coffee flavors can arise from roasted malts or adjuncts used in brewing, creamed corn is often associated with diacetyl or other off-flavors related to the brewing process, and herbal flavors may come from hops or other botanicals added to the beer. Understanding the sources of these flavors helps to appreciate the fermentation process and how yeast contributes to the final taste profile of beer.
