Difference between ground coffee and coffee grounds

Don't confuse them! Ground coffee is the finely processed beans used for brewing. It's what you typically buy in a store, ready to be used in your coffee maker or espresso machine.

Coffee enthusiasts reuse coffee grounds to enhance composting and gardening operations. It doesn't end there; grounds can be valuable in beauty therapies like DIY treatments and act as cleaning agents.
