You can re-brew the coffee grounds a second time, with great flavor. Just dilute with water to taste. While not as flavorful, you can even brew the grounds a third time! We call it Three-Brew. The BOD® system was built with Re-Brewing and Three-Brewing in mind and makes the process easy. Forget about Re-Brewing with a hot brew machine, we all know it's totally undrinkable. The BOD® makes re-brewing easy, and delicious while stretching your coffee dollar.
