Water isn't the only thing you drink, the pint is designed to be transformed into a cup to better match its contents.
No need for any heavy duty bottle brushes, the base of the cup is removable to allow for easy cleaning. The 16oz bottle is insulated with two walls of stainless steel keeping your coffee hot and your beer cold.
