Two chemists
who couldn't stop
chasing the roast.
Ember & Ash was born in a converted warehouse in Oakland, 2019 — founded by Nadia Chen and Marcus Webb, a food scientist and a structural engineer who found their shared obsession in the Maillard reaction. Not the idea of it. The actual chemistry: the 140°C window where amino acids and reducing sugars collide into the caramelized, complex compounds that make a truly exceptional cup.
Every bean we roast is sourced directly from farmers we’ve visited, broken bread with, and returned to. Small-batch means 15–25 kg per run. We cup every batch before it leaves the building. If it doesn’t make us put down our phones and just — drink — it doesn’t ship.
