After untold amounts of research into the properties of PET plastic, we fanatically chose to make the Big Mouth Bubbler™ with as little plastic as possible while still maintaining a high degree of structural integrity and brute strength. What does this all mean? It means that the impact to our planet Earth is as minimal as possible. We call this a win-win situation. Check out the Plastic Big Mouth Bubbler™ for yourself. You will never go back to a traditional style carboy again.
