Coffee Bean Guide

Coffee Bean Guide

Coffee beans are the seeds of the Coffea plant's fruit, often referred to as coffee cherries. These beans are one of the most beloved and widely consumed beverages globally, cherished for their rich aroma and stimulating properties due to caffeine content. There are two main types of coffee beans: Arabica and Robusta, each with distinct flavors and characteristics.


Production Process:

  1. Cultivation: Coffee plants thrive in tropical climates along the equatorial region known as the "Bean Belt." Arabica beans prefer higher altitudes and cooler temperatures, while Robusta beans are hardier and can grow in lower altitudes and warmer climates.
  2. Harvesting: Coffee cherries are typically hand-picked when they are ripe and red. This labor-intensive process ensures the best quality, as cherries ripen at different times.
  3. Processing: Once harvested, the cherries undergo processing to extract the beans. There are two main methods:
    • Dry Processing: Cherries are spread out in the sun to dry. Once dried, the outer layers are mechanically removed.
    • Wet Processing: Cherries are soaked in water, where the ripe ones sink and the unripe float. The outer layers are then removed, leaving the beans, which are further fermented in water to remove the mucilage and then dried.
  1. Milling: Dried beans are hulled to remove the parchment layer, polished, graded, and sorted.
  2. Roasting: Green coffee beans are roasted at high temperatures to develop flavor and aroma. Roasting levels vary from light to dark, significantly impacting the taste. Coffee beans are then left to de-gass for 24 hours before further processing.
  3. Grinding: Roasted beans are ground to varying degrees of fineness, depending on the brewing method.
  4. Brewing: Ground coffee is brewed using various methods like drip, espresso, French press, or pour-over, each yielding a different flavor profile.
  5. For Energy Pods: We roast beans in-house to a sunlit roast, a type of roast under light roast but above gold roast, and add these beans right away into our grinding process to maximize flavor and taste. Due to our extensive and unique process, the beans continue to de-gass as they are ground further into our Energy Pods.



  • Beverages: The primary use of coffee beans is in making coffee beverages, ranging from traditional black coffee to espresso-based drinks like lattes and cappuccinos.

Types of Coffee Roasts

Coffee roasts vary widely, each offering a unique flavor profile and aroma. The roast level significantly impacts the taste of the coffee. Here are the primary types of coffee roasts:

  1. Light Roast: Lightly roasted coffee beans have a light brown color and no oil on the surface. These roasts have the highest acidity and retain most of the original coffee bean's flavor, often resulting in a more complex and nuanced taste. Common terms for light roasts include Light City, Half City, and Cinnamon Roast.
  2. Medium Roast: Medium-roasted beans have a richer brown color and a more balanced flavor, aroma, and acidity. They are often preferred in the United States and are sometimes referred to as American Roast. Medium roasts preserve many of the unique flavors of the coffee bean while also offering a slight increase in the body compared to light roasts.
  3. Medium-Dark Roast: These beans have a darker brown color with some oil on the surface. The flavors from the roasting process become more pronounced, with a slight decrease in acidity. Medium-dark roasts, such as Full City, have a bittersweet aftertaste and a fuller body than medium roasts.
  4. Dark Roast: Dark-roasted coffee beans have a shiny black color with an oily surface and a pronounced bitterness. The flavors of the roasting process dominate, and the original flavors of the bean are mostly overshadowed. Common names for dark roasts include French Roast, Italian Roast, Espresso Roast, and Continental Roast. These roasts are typically used for espresso.
