Keg drinks need to be cooled for a number of reasons. Firstly, refrigeration helps to slow down the natural process of spoilage, which can be accelerated by higher temperatures. When kegs are stored at warmer temperatures, it becomes more susceptible to bacteria growth and other contaminants that can affect its flavour, aroma, and overall quality. Additionally, cooler temperatures help to preserve the carbonation, which is an important aspect of its taste and texture. Drinks that are too warm may lose its fizz and taste flat. Finally, serving at the right temperature can enhance a drinks flavour profile and make it more enjoyable to drink.
