Expiration & Storage Tips
When does espresso expire?
Unopened espresso beans, if stored in a cool, dry place, will remain fresh for about 6 to 9 months from the date of manufacture. Once opened, espresso beans will start to lose their freshness after two weeks. You may still use the beans for up to a month, but you'll notice a significant drop in flavor after two weeks. Ground coffee, on the other hand, has a shorter shelf life; once opened, it begins to lose its potency almost immediately and is best used within a week. Homemade brewed espresso doesn't hold its freshness for long, as it starts to taste stale after just 1-2 hours if left unrefrigerated. If frozen, espresso beans can last for 3 to 6 months without losing their quality.
How do you tell if espresso is bad?
For espresso beans, the glossy, oily sheen might fade as they get older, signifying a potential loss in flavor. Even more telling is the smell—it should smell rich and potent at first opening. If it doesn't, it's probably past its prime. If the brewed espresso smells burnt or has a bitter aftertaste, there's a good chance it's stale. Also, if your homemade brewed espresso turns cloudy or lacks the characteristic crema, it's a sure sign that it's gone bad.
Tips for storing espresso to extend shelf life
• Unopened bags of espresso beans should be stored in a cool, dry place; avoid places exposed to heat and direct sunlight.
• Once opened, transfer the beans to an airtight container to keep out oxygen and moisture.
• Don't store beans in the refrigerator as the condensation can spoil them; instead, keep them at room temperature.
• If you must store them for longer periods, freeze the beans in a vacuum-sealed bag to retain their freshness.
• Brewed espresso should be consumed right away for the best quality; if you need to store it, refrigerate it and consume within a day.
