aromas, we look for other sources of flavor substances to see if we can promote fermentation to produce the flavor we want. Today, Micet engineers first take you to understand the esters and the factors that affect them.
Control esters
Types of Esters in Beer
- Isoamyl acetate – ripe banana flavor, when the content of isoamyl acetate is low, the mellow flavor of the beer is stronger; when it is high, the ester flavor and solvent flavor are enhanced. When the concentration is controlled at 1mg/kg-2mg/kg, the quality of the beer is the best.
- Ethyl acetate – Nail polish remover smell (solvent smell) at higher levels. When the ethyl acetate content in beer is low, the hop aroma and mellow aroma are strong, and the aroma is not harmonious. Control its concentration between 15mg/kg-25mg/kg, the aroma of the beer is the purest.
- Ethyl Caproate – Pear, Apple, Pineapple flavors. When the content is low, the aroma of hops is strong, and the aroma of the wine body is not soft enough; when the content is too high, the aroma of the wine is too strong, and the aroma of hops is reduced, which is close to the aroma of liquor. Generally, the concentration is controlled between 0.1mg/kg and 0.25mg/kg. Now, the aroma of the beer is the best.
- Ethyl Butyrate – Tropical Fruit Flavor
- Ethyl Caprylate – Apricot, Pineapple Flavor
The link between beer style and esters
Factors influencing the formation of esters
Low-temperature fermentation is believed to produce beer with improved taste and aroma as well as high ethanol and beer productivity. To save energy, space, and time, breweries use high specific gravity wort and ferment it at higher temperatures. The correct choice of process temperature, especially in the initial stages of fermentation, is crucial for the rapid propagation of yeast.

Yeast species and addition amount
Wort composition and concentration
Now, even if the dissolved oxygen and the inoculum of the wort increase at the same time, the yeast will not increase in proportion to the increase in concentration, resulting in a decrease in the synthesis of fatty acids and an increase in the production of esters. Thus, the high concentration of diluted beer has higher ester content than the beer fermented at the same concentration, and the possibility of beer flavor defects is higher.
