Which temperature range is considered suitable for beer storage in a keg?

The suitable temperature range for beer storage in a keg is typically between 38°F and 45°F. This range ensures that the beer is kept cool enough to maintain its freshness and flavor profile without risking spoilage or negative effects on the beer's carbonation.

At temperatures below 38°F, certain beer styles, especially those with more delicate hop characteristics or already-low levels of carbonation, may become too cold, which can hinder their flavor expression and mouthfeel. Conversely, temperatures above 45°F can lead to excessive warming, resulting in foaming issues when poured, the development of off-flavors, and an accelerated deterioration of quality due to enzymatic and bacterial activity.

Maintaining beer within this ideal range helps preserve its intended taste and aromatic qualities, making it essential for optimal quality when serving from a keg.
