It's okay to water plants with leftover coffee or to add coffee grounds to the compost pile but learning when and why to use coffee in the garden will protect your plants.

If you keep brewed coffee in a sealed container in the fridge, it may last longer. It's likely safe to consume for up to 3–4 days when stored this way. However, it probably won't taste that good. If you add milk or creamer to your brewed coffee, drink it within 2 hours if left at room temperature.

Coffee grounds are packed with nutrients that tomato plants love, like nitrogen, potassium, and phosphorus. They help improve soil structure and promote microbial activity, which can lead to healthier, more robust tomato plants. Plus, they may even help deter certain pests.

Fresh coffee that has been freshly brewed can only be left at room temperature for 30 minutes without significantly losing flavor and is still safe to consume after 24 hours though the coffee would start to taste bitter and have odd flavors.

You can store ground coffee in the freezer for 6-12 months. Don't open the coffee grounds prior to freezer storage. Get a zip-lock freezer bag and put the unopened bag in there as an extra precaution. With a valve bag, this extra step will keep out any potential moisture from the freezer from getting in.

The fridge is not the place to store coffee in any form, ground or whole bean even if in an airtight container. It isn't cold enough to keep your coffee fresh, and because coffee works as a deodorizer, it will absorb all the aromas in your fridge.

There may be days when you don't feel like going through the process of brewing coffee, so how long can coffee sit out?
