How did you prep to become a Q-Grader? 🥄
Marc Marquez (@marcnmarquez on Instagram) talks about the way he prepared to take the Q test (while brewing some delicious Big Island Coffee Roasters, or @bigislandcoffeeroasters on Instagram, coffee!)
Disclaimer, this is not a guaranteed way to pass the Q, just Marc’s anecdotal experience. 🙂
