The word "organic" refers to anything that is naturally produced or grown. It does not include any artificial product in its growth, and hence it does not harm.  

Organic coffee is coffee that has been cultivated using organic agricultural methods and standards, with little use of synthetic chemicals and prohibitions on the use of artificial fertilizers, pesticides, and herbicides.

Organic can also apply to farms or farm products that include socially responsible practices, including recycling, composting, soil health, and environmental protection. Organic farms also help address climate change by releasing less carbon and sequestering considerable amounts of carbon compared to chemical farms. Organic coffee is a good alternative if you're a coffee consumer who prefers a diet free of synthetic chemicals.

Organic coffee is often healthier than non-organic coffee and the caffeine in this form of coffee is generally more potent than that found in non-organic brands. This means that one cup of organic coffee might provide the equivalent of four cups of non-organic coffee in terms of energy enhancement.

Organic coffee being free of pesticides and synthetic fertilizers is also the much healthier option as some non-organic coffees may contain chemicals from pesticides and fertilizers which can potentially lead to health problems.

As a suggestion always check that "organic" coffee has an authentic certified organic stamp and provider number.
