What are the factors that affect the quality of the beer?

Beer goes bad because of two reasons. One is the oxidation process which occurs during storage and the other is the contamination of microorganisms. Beer gets oxidized when exposed to air which results in the formation of off flavors and color changes. It also affects the taste of the beer. Microbes such as yeast and bacteria spoil beer by producing alcohol and carbon dioxide. These microbes produce enzymes that break down proteins and carbohydrates present in the beer. This leads to the production of undesirable tastes and odors.


Temperature plays a major role in the quality of beer. High temperatures accelerate the rate of oxidation and lead to faster deterioration of the beer. Low temperatures slow down the rate of oxidation and allow the beer to age longer. A good rule of thumb is to store the beer in the refrigerator between 45°F 7°C and 55°F 13°C. Storage

Beer spoils quickly because of the yeast and bacteria present in it. Beer contains alcohol, sugar, and other nutrients that support the growth of these microorganisms. These organisms produce carbon dioxide gas as a result of fermentation. Carbon dioxide gas is what gives beer its fizzy taste. To prevent beer from spoiling, store it properly. Refrigerate it immediately after opening. Keep it cool and dark. Do not expose it to light. Make sure the storage area is dry. Do not leave it standing upright. Store it horizontally. This prevents oxygen from reaching the beer. It also keeps the beer from getting warm.
