As an expert sommelier and brewer, I can provide you with some insights on whether Campari should be refrigerated. Campari is a unique and flavorful Italian liqueur that is known for its fruity and botanical taste.
While it is not necessary to refrigerate Campari, it can help to preserve its flavor if you don't finish the open bottle within a couple of days. The reason for this is that Campari is processed in a way that allows it to be stable at room temperature. Its alcohol content of 20% also plays a role in its stability.
Refrigerating Campari can slow down the oxidation process, which can affect the flavor of the liqueur over time. By keeping it in the fridge, you can help maintain the freshness and vibrant flavors for a longer period. However, it's important to note that refrigeration is not essential and Campari can still be enjoyed at room temperature.
In my personal experience, I have found that keeping Campari refrigerated can be beneficial, especially if I know that I won't be finishing the bottle within a short time. It helps to ensure that I can enjoy the full flavor profile of Campari even after a few days or weeks.
To summarize, while it is not necessary to refrigerate Campari, doing so can help preserve its flavor and freshness for a longer period. The choice of refrigeration ultimately depends on personal preference and the duration for which you plan to keep the open bottle.
