To understand how long coffee lasts in the fridge, it’s essential to consider the type of coffee and its storage method. Here are the main categories to keep in mind:

1. Brewed Coffee

Once brewed, coffee is best consumed fresh. However, if you find yourself with leftover coffee, here’s what you should know:

• Refrigeration: Brewed coffee can be stored in the fridge for about 3 to 4 days. Make sure it’s in an airtight container to minimize oxidation and absorption of other fridge odors.
• Freezing: If you want to extend its life, you can freeze brewed coffee in ice cube trays. These coffee cubes can be used later in recipes or to chill iced coffee without dilution.

2. Coffee Beans

Whole coffee beans maintain their freshness much longer than brewed coffee. Here’s how to store them:

• Storage Time: Unopened, whole coffee beans can last for up to 6-12 months in the fridge. Once opened, they should ideally be used within 3 to 6 months.
• Storage Tips: Store your beans in an airtight container to protect them from moisture and odors. However, refrigeration isn’t always necessary; a cool, dark cupboard can also be effective.

3. Ground Coffee

Ground coffee has a shorter shelf life than whole beans due to its increased surface area, which exposes it to air and moisture:

• Storage Time: Ground coffee can last about 3 to 5 months in the fridge if stored properly. However, it’s best to consume it within a month for optimal flavor.
• Storage Tips: Similar to whole beans, keep ground coffee in an airtight container. Freezing can also work, allowing you to portion out smaller amounts to maintain freshness.

4. Coffee Creamers

Dairy or non-dairy creamers can also impact the longevity of your coffee. Here’s what to know:

• Dairy Creamers: Once opened, dairy creamers should be used within 1 to 2 weeks if stored in the fridge. Check the expiration date on the carton, as that can vary.
• Non-Dairy Creamers: These tend to last longer, around 2 to 3 weeks after opening. Again, check the label for specifics.

Signs That Your Coffee Has Gone Bad

Regardless of how well you store your coffee, it can eventually spoil. Here are some signs to look out for:

• Off Smell: Fresh coffee has a rich aroma. If it smells stale or has a rancid odor, it’s time to toss it.
• Flavor Changes: If your coffee tastes sour, bitter, or otherwise off, it’s best not to drink it.
• Appearance: For brewed coffee, any visible mold or strange film indicates spoilage.
