Is Coffee Good for Compost?

Is coffee good for compost?

The short answer is YES.

Coffee, either the grounds or the liquid are very good for your compost. Coffee grounds are a Green or a Nitrogen source and will heat up your compost pile very quickly. I read about a gentleman who added coffee grounds to his compost pile. It heated up to 140-150 degrees F for 2 days.

Most people think coffee or coffee grounds are a Brown when it comes to composting because it has a lot of Carbon, a C/N ratio of 20:1, but coffee grounds also have a lot of Nitrogen.

Liquid coffee is great for plants and your compost pile. It’s similar to compost tea. It’s filled with nutrients and beneficial microbes. Microbial action explodes when you pour coffee on compost.

If you are a coffee drinker/brewer save the grounds and filters. Throw them in your compost. They will accelerate decomposition and make super compost for your garden or yard. Don’t go overboard with it though. A little goes a long way. Don’t make half your compost pile coffee grounds.
