As an expert sommelier and brewer, I can share my knowledge and personal experiences on the topic of homemade falernum and its shelf life. Homemade falernum is a versatile and flavorful syrup that adds depth and complexity to cocktails. It is made by infusing rum with various ingredients such as lime zest, cloves, and almonds, and then sweetening it with sugar.
When it comes to the shelf life of homemade falernum, it is important to consider the ingredients used and the storage conditions. Generally, homemade falernum can last for several weeks to a month if stored properly. However, it is worth noting that the flavors may change or become less vibrant over time.
The lime zest, which provides the refreshing citrusy flavor, is one of the key ingredients in falernum. It is recommended to use fresh and organic limes for the zest to ensure the best quality and flavor. The lime zest contains essential oils that contribute to the overall taste of the falernum. Over time, these oils may start to lose their potency, resulting in a less pronounced lime flavor.
Another important ingredient in homemade falernum is the sugar used for sweetening. Sugar acts as a preservative and helps extend the shelf life of the syrup. However, it is important to note that sugar can also attract moisture, which may lead to the growth of mold or spoilage if not stored properly.
To maximize the shelf life of homemade falernum, it is crucial to store it in a cool, dark place away from direct sunlight. Sunlight can accelerate the degradation of flavors and potentially spoil the syrup. It is also recommended to use airtight containers to prevent oxidation and the introduction of any contaminants.
I personally have made homemade falernum numerous times and found that it typically maintains its flavors and freshness for about a month when stored correctly. However, I have noticed that the intensity of the lime flavor gradually diminishes over time. This is why I prefer to make smaller batches of falernum to ensure its optimal taste and quality.
Homemade falernum can be stored for several weeks to a month if stored properly in a cool, dark place. However, it is important to note that the flavors may change over time, especially the lime zest's potency. To enjoy the best quality falernum, it is recommended to consume it within a month of preparation.
