Logistics 101 | 5. What is the fifth step in the coffee supply chain?

Definition:

• The fifth step in the coffee supply chain is the roasting of coffee beans.

Explanation:

• Roasting transforms green coffee beans into the aromatic, flavorful beans that we brew into coffee. This process involves heating the beans to high temperatures, causing chemical changes that develop the beans' flavor and aroma. Roasting profiles vary, with light, medium, and dark roasts offering different taste characteristics. The roasting process must be carefully controlled to achieve the desired flavor profile.

Real-Life Application:

• Specialty coffee shops, such as those in the United States, often roast their beans in-house to ensure freshness and customize flavor profiles. Large coffee companies, like those in Italy, use industrial roasters to produce consistent, large-scale batches that meet consumer demand.
