## About

Mount Diablo Brewing Company was created out of a love for homebrewing, and was influenced by a deep appreciation of this majestic mountain and its surrounding open spaces even before that.

O’Neill started homebrewing over 25 years ago. What started as a hobby evolved into a serious passion, fast becoming the fully formed local institution of craft beer it is today.
