Light Roast vs. Dark Roast Coffee Explained

Coffee lovers often debate which roast is better. I get asked a lot about the differences between light roast and dark roast coffee. Both have their fans and unique qualities. I want to break down the key points so you can decide what suits your taste and lifestyle best.

What Makes Light Roast and Dark Roast Different?

The main difference lies in how long the coffee beans are roasted. Light roast beans are roasted for a shorter time at lower temperatures. Dark roast beans stay in the roaster longer and at higher heat.

• Light roast beans keep more of their original flavor. They taste brighter, more acidic, and often have fruity or floral notes.

• Dark roast beans develop a stronger, bolder flavor. They taste more bitter, smoky, and sometimes chocolaty.

  
  

The roasting process also changes the color and texture of the beans. Light roast beans are light brown and dry. Dark roast beans are dark brown or almost black and oily.
