And yes, Mama Rosa does still taste-test every single batch.
It started in Rosa Delgado's kitchen in Austin, Texas in 2019. She'd been roasting her own beans for years — a habit she inherited from her father in Oaxaca, who roasted coffee over an open fire every Sunday morning. The smell of it became the smell of home. Of safety. Of family.
When her son Marcus came home from college complaining that no coffee hit like grandpa's, Rosa decided it was time to share it with the world.
Marcus quit his marketing job. His sister Camila, who was studying design in Brooklyn, came home to build the brand. Their dad, Eddie, converted the garage into a roastery — setting up the equipment between a lawn mower and a broken dryer. And Grindz Coffee was born — right there on Maple Street, in the house Rosa has lived in for 22 years.
We officially launched in January 2025. We sold out of our first 50 bags in 6 hours. Rosa cried. Eddie said "I told you so." Marcus called Camila from the parking lot of a UPS store, screaming. That was the moment we knew this was real.

The people behind every bag.

Head Roaster & Mom
"If she doesn't approve it, it doesn't ship. She has never, not once, lowered her standards. The roastery smells amazing because of her."

Co-Founder & CEO
"Former marketing guy. Current coffee evangelist. Still can't fold boxes as fast as Camila. Has tried to rebrand 'Dad's Garage' exactly four times. Rosa said no."

Creative Director & Co-Founder
"Designed the logo on a flight home from Brooklyn. Said it would take 20 minutes. It took 11 hours. Worth every single minute."
Three things we'll never compromise on.
Every decision we make, we ask: would Rosa be proud of this? That question has kept us honest since day one. It always will.
We visit every farm. We know every farmer. We don't buy from people we haven't shaken hands with. Full stop.
No gatekeeping. No jargon. No pretension. If you like coffee, you're welcome here. The best cup is the one you actually enjoy.
