As a sommelier and brewer, I can confidently say that Angostura bitters do have a shelf-life, but it is quite long. While most bitters are recommended to be used within 5 years, Angostura bitters can last nearly indefinitely if stored properly. However, it's important to note that they may lose some of their potency and flavor over time.
One common question that arises is whether Angostura bitters have an expiration date. Unlike many food and beverage products, Angostura bitters do not come with a specific expiration date. This is because they are made with high-proof alcohol, which acts as a preservative and helps to extend their shelf-life.
That being said, it's always a good idea to check the appearance, smell, and taste of your Angostura bitters before using them, especially if they have been sitting on your shelf for a long time. Over time, the flavors may become muted or altered, affecting the overall quality of the bitters.
Personal experiences have shown me that even after several years of storage, Angostura bitters can still be used and enjoyed. However, the intensity of the flavors may diminish, and you may need to use a bit more to achieve the desired taste in your cocktails or recipes.
To ensure the longevity of your Angostura bitters, it's recommended to store them in a cool, dark place, away from direct sunlight and heat sources. This will help prevent any degradation of the flavors and maintain their quality for a longer period.
While Angostura bitters do not have a specific expiration date, they can go bad over time. However, when stored properly, they can last for many years without significant loss of quality. It's always a good idea to check the appearance, smell, and taste before using them, especially if they have been stored for an extended period.
