Where does Starbucks get their coffee from?

I'm curious to know, where exactly does Starbucks source their coffee beans from? Are they partnering with specific farmers or cooperatives in different regions of the world? Do they have a strict set of criteria for selecting their suppliers, ensuring that the coffee meets their high-quality standards? And how does their supply chain management process work to ensure timely delivery of fresh, flavorful coffee to their stores globally? I'm eager to learn more about the origins of the coffee that fuels our daily caffeine fix at Starbucks.
