The Process of Roasting Coffee – Shiba Coffee and Tea Co
Coffee roasting is an art that requires precision and experience to produce a high-quality cup of coffee. At Shiba Coffee and Tea Co, we are committed to providing our customers with the best coffee experience possible. In this article, we’ll take a closer look at the process of roasting coffee and the key factors that contribute to a great cup of coffee.
The Basics of Coffee Roasting
Coffee roasting is the process of heating green coffee beans to bring out the natural flavors and aromas. The roasting process transforms the green, unroasted coffee beans into the brown beans that we know and love. The temperature and length of the roasting process will impact the final flavor and aroma of the coffee.
The Three Stages of Coffee Roasting
- Drying Stage: The moisture in the coffee beans is reduced as the heat is applied.
- Development Stage: The coffee beans continue to darken as the heat continues to be applied. The sugars in the beans begin to caramelize and create new flavors.
- Finish Stage: The coffee beans reach the desired roast level and are removed from the heat source.
Factors that Impact the Final Flavor of Coffee
- Origin of the Coffee Beans: The location where the coffee beans are grown will impact the final flavor of the coffee. Different regions of the world produce coffee with unique flavor profiles.
- Roast Level: The roast level will impact the final flavor of the coffee. A lighter roast will result in a brighter, more acidic flavor, while a darker roast will result in a stronger, more bold flavor.
- Roasting Method: The method used to roast the coffee beans will impact the final flavor of the coffee. Different roasting methods will result in different flavor profiles.
At Shiba Coffee and Tea Co, we are committed to using the best coffee beans and the finest roasting methods to produce a high-quality cup of coffee.
The beans arrive to us in large burlap bags weighing in at 45-70 Kilograms depending on where they come from. After we check the beans to make sure everything is good we can begin the roasting process.
Now the roasting begins, we preheat the roaster to 450 degrees so when we add the beans the temperature is stable and doesn’t sharply drop. Roasting requires the use of all of your senses. We constantly monitor the temperature throughout the process to ensure the perfect roast profile for the beans we roasting. As the beans reach different points in the roast the temperature will change and we use these temperature changes to help figure out where we are in the roast process. We use the sound of the beans as well, the sound of the beans in the roaster change throughout the process as well. It is also extremely import to listen for the first crack. This is when the bean has gotten hot enough for the chemistry inside to start changing and a high quality bean will almost sound like popcorn popping when it cracks. After the first crack there will be a second crack later in the roasting process depending on the roast. As the beans roast their smell will also change as will their color. They will go from a brown-green color to that classic coffee brown-black color.
Once the beans hit the perfect roast we remove them from the roaster and put them in the bean cooler. This is to cool them down evenly and as quickly as possible so they do not continue to roast as they sit. The bean cooler constantly pulls air through the beans to ensure they cool quickly and evenly.
Now that the beans are roasted and cooled we can now fulfill your order, grinding and packaging to your specifications.
