What fruit aroma is typically associated with ethyl butyrate?

Ethyl butyrate is an ester that is commonly associated with a strong aroma reminiscent of pineapple. This compound is formed during fermentation, particularly in certain yeast and bacterial strains, and it contributes to the fruity character found in various beverages, including beers, wines, and ciders.

The pineapple aroma from ethyl butyrate can enhance the perception of tropical fruit notes in beer, contributing to the overall flavor profile, especially in styles such as IPAs or those made with fruit additions. When brewers aim to achieve a certain fruity profile, they often target specific esters like ethyl butyrate for its distinctive pineapple scent, making it a desirable component in crafting flavorful products.

Other listed fruits, such as banana, apple, and cherry, are indicative of different esters or compounds. For instance, the banana aroma is typically associated with isoamyl acetate, while apples might have a connection to ethyl acetate and other compounds. Each compound contributes its unique sensory characteristics, but ethyl butyrate is specifically linked to the pineapple aroma, which is why it is the correct choice in this context.
