What is the standard temperature of draft system operation?

The standard temperature for draft system operation is typically set at 38°F. This temperature is optimal for preserving the quality and flavor of the beer while ensuring it is cool enough for refreshment. At this temperature, beer can maintain proper carbonation and minimize the risk of spoilage due to temperature fluctuations that lead to off-flavors.

Maintaining a temperature around 38°F also helps prevent foaming issues when pouring, which can occur if the temperature is too low or too high. For example, if the beer is served at too low a temperature (like 28°F or even freezing), it could become overly frosty and impact the taste profile negatively. Conversely, serving at too warm a temperature (like 40°F) might lead to excessive carbonation release and could make the beer taste flat. Thus, establishing a target of 38°F helps strike a balance between flavor integrity and pourability.
