   – Dark roasts often exhibit lower acidity. They may result in a smoother, heavier flavor that can include chocolate or nutty undertones.

2. Sweetness:
   – Light roasts can have a pronounced sweetness due to their natural sugars. This sweetness is highlighted when brewed cold.
   – Medium roasts generally contain more caramelization, leading to a richer sweetness. This sweetness emerges from the roasting process, which develops sugars beyond those in the raw bean.
   – Dark roasts produce a more intense, bittersweet profile. The extended roasting time can lead to a decrease in perceived sweetness compared to lighter roasts.

3. Bitterness:
   – Light roasts are less bitter. They retain more of the bean’s natural flavors without heavy roasting influences.
   – Medium roasts have moderate bitterness. The balance between sweetness and bitterness makes them versatile for diverse cold brew styles.
   – Dark roasts are more bitter due to the breakdown of sugars and other compounds. The bitterness can deliver a robust flavor profile appropriate for certain preferences.

4. Overall Complexity:
   – Light roasts are complex and can present a wide array of flavors. Their nuances in cold brew often make them suitable for those seeking a more vibrant coffee experience.
   – Medium roasts offer a harmonious complexity, combining multiple flavors without overwhelming the palate.
   – Dark roasts provide a consistent and bold flavor profile. Their complexity is often characterized by deep, rich notes rather than a range of flavors.

Together, these factors shape how each roast level translates to cold brew coffee. Understanding these influences helps coffee enthusiasts choose their preferred roast to suit their taste preferences.
