Expert Perspectives on Reusing Coffee Grounds

Dr. Emily Carter (Food Scientist, Sustainable Brew Institute). “Reusing coffee grounds can be beneficial not only for reducing waste but also for enhancing the flavor profile of subsequent brews. However, it is essential to note that the second extraction may yield a weaker flavor, so it is best suited for those who prefer a milder cup.”

Mark Thompson (Environmental Consultant, Green Coffee Solutions). “From an environmental standpoint, reusing coffee grounds is a fantastic practice. They can be repurposed as natural fertilizers or even used in beauty products. This not only minimizes waste but also promotes a more sustainable lifestyle.”

The grounds lose a significant amount of their oils and flavors after the first brew, which can lead to a less satisfying cup. I recommend using them for cold brews or as a base for other recipes instead.”
