Est. Castro Valley
Every great day begins
with a cup you can trust.
At Cornerstone Coffee Brewing Co., we pour intention into every pour — from single-origin beans roasted to order to pastries baked fresh each morning. This is your neighborhood cornerstone, where the coffee is honest, the atmosphere is warm, and the community is family.
Our Story
Rooted in the neighborhood we call home.
Cornerstone Coffee Brewing Co. was born from a simple conviction: that the best coffee isn't found in a rush — it's savored. Located on Redwood Road in the heart of Castro Valley, we've become a gathering place for neighbors, students, and anyone who believes a great cup of coffee is worth the wait.
Our beans are sourced from sustainable farms and roasted with care. Our bakers arrive before dawn. Our baristas know your order — or at least they're eager to learn. Every detail is chosen so that stepping through our door feels like coming home.
