Does Coffee Go Bad? Tips and Tricks to Extend Its Shelf Life

Quick summary: Yes, Coffee can go bad. It does not spoil in the traditional sense but its flavor and quality degrade over time. Unopened coffee beans last up to a month, ground coffee around two weeks, and instant coffee about two weeks. Once brewed, coffee should be consumed within 12 hours or refrigerated for up to three days.

Coffee lovers don’t have too many problems with the duration of their favorite beverage. If you drink two or three cups a day, you will probably drink the whole bag in an ideal two to three weeks, which is the maximum consumption period coffee should have after opening the bag.

Problems arise when you stretch the package for a month or more. Even if you are not the biggest coffee fan, you will notice a difference in the taste that has popped up.

To answer the first question asked, can fresh coffee be spoiled at all? No. But the loss of flavor will be so significant that any friend will resent you for serving old coffee. Here are the details.

How Long Does Coffee Last?

The durability of coffee is actually very low. As we said, spoilage will not be such that you get sick of old coffee beans, but the impact on taste quality is tremendous. Manufacturers pack coffee in vacuum bags or under controlled pressure to ensure flavor for a longer time.

The expiration date on the packaging will be the best guide to durability, and we suggest you don’t exceed that date if you want a delicious drink. Here are the tips for the duration once you open the package.

Whole Coffee Beans

If you want to enjoy your favorite coffee for longer, we suggest you buy whole coffee beans and then grind the amount you need at the moment. Whole beans will best preserve the aroma and probably last up to a month without losing the taste quality. After that, there’s much chance of getting stale coffee beans, so don’t stretch it.

Ground Coffee

Ground coffee will be more prone to loss of aroma, so the best advice is to consume it within two weeks of opening the package. Nothing will happen if you extend that deadline to an extra week. But everything after that, you will probably feel on your palate. So if you are not a fanatic coffee drinker, buy whole bean coffee instead.
