Bona Fide invented a patent pending process, we call “Craft Draft”, which embeds our flavor stability technology into our kegs for at least 90 days. That is 3 times the life of our closest competitor. Every keg we produce is created using the Craft Draft process. We extract the best flavor from the coffee or tea, maintain the volatile nuance flavors of that each variety presents and preserve them under strict sanitation and preservation standards.
