The reason Angostura Bitters don't need refrigeration is due to their unique composition. With an alcohol content of around 44.7%, they are self-preserving, which means they can withstand temperature fluctuations and humidity without spoiling. This is similar to how vinegar or hot sauce can be stored at room temperature without refrigeration.
Another factor that contributes to the shelf-stability of Angostura Bitters is the use of natural preservatives like gentian root and orange peel. These ingredients not only add flavor but also help to prevent the growth of bacteria and mold. This means you can enjoy your Angostura Bitters for a long time without worrying about them going bad.
