As a sommelier and brewer, I can provide some insights into whether or not you need to refrigerate Salers. Salers is a French liqueur that is traditionally made from the gentian root and other botanicals. It has a distinct bitter flavor and is often enjoyed as an aperitif.
While Salers is no longer bottled as a wine-based maceration, it is still recommended to refrigerate open bottles of Salers. The reason for this recommendation is not because Salers will go bad, but rather because refrigeration can help preserve the lighter aromatic compounds in the liqueur. Like wine, these aromatic compounds can dissipate once the bottle is opened and exposed to air.
Refrigerating Salers can help slow down the oxidation process and keep the flavors and aromas of the liqueur intact for a longer period. By keeping it chilled, you can enjoy Salers at its best and experience its full range of flavors.
I have personally found that refrigerating open bottles of Salers can indeed help maintain its freshness. I have noticed that when I leave an open bottle of Salers at room temperature for an extended period, the flavors and aromas tend to diminish over time. However, when I refrigerate the bottle, the liqueur retains its vibrant and aromatic qualities for a longer period.
It's worth mentioning that refrigeration is not absolutely necessary, especially if you plan to consume the Salers within a short period. If you are planning to finish the bottle within a week or two, keeping it in a cool, dark place should be sufficient. However, if you want to preserve the delicate flavors and aromas for an extended period, refrigerating the bottle is the way to go.
To summarize, while refrigerating Salers is not mandatory, it can help preserve the lighter aromatic compounds and maintain the freshness of the liqueur. By keeping the bottle chilled, you can enjoy Salers at its best and savor its unique flavors.
