What is one goal of Starbucks' coffee buying guidelines?

One of the primary goals of Starbucks' coffee buying guidelines is to ensure high-quality coffee. This commitment is fundamental to the brand's identity and reputation. By prioritizing quality in its sourcing practices, Starbucks seeks to select coffee beans that meet rigorous standards related to flavor, aroma, and overall characteristics. This involves working closely with coffee farmers and suppliers to establish relationships based on mutual respect and sustainability, ultimately aiming for a product that appeals to customers and reflects the brand's values.

The other options do not align with the core mission of Starbucks regarding its coffee sourcing. For instance, while profit margins are important for any business, they are not the main focus of the coffee buying guidelines. Similarly, dominating the coffee market and standardizing pricing do not directly pertain to the quality assurance emphasis embedded in their sourcing practices.
