Different Coffee Roasts Explained

You’ve likely heard of Light, Medium or Dark coffee roasts before, but what do they really mean? These roast levels aren’t as simple as they sound, each one can drastically change the flavour profile of your coffee. From aroma to body to taste, understanding these three roast levels will unlock a world of nuance in your morning cup.

But don’t worry, we’re here to break it down for you.

 

The Basics of Coffee Roasting

Before we jump into roast levels, let’s talk about what coffee roasting is. Coffee beans are actually greenish in colour and quite mushy before they’re roasted. They also don’t have that wonderful aroma we know and love until they’ve gone through the roasting process.

Roasting coffee is when the beans are transformed from being sour and grassy to sweeter and richer.

The roasting process is what causes coffee beans to darken and release those delicious aromas. As the coffee bean heats up, the sugars start to caramelise and the acids will develop (or sometimes diminish). Hundreds of flavour compounds will eventually form, which all affect the taste of the coffee you enjoy. This is also what causes different roast levels to have such unique flavours.


Light Coffee Roast

Light roast coffee is roasted for a shorter period of time, which means the beans will retain more of their original flavor characteristics. The beans will also have a much lighter color than medium and dark roasts. Flavour wise, expect a much brighter coffee with increased acidity. You may also be able to taste floral, fruity, or citrus notes.

Pros:

  • Lighter body
  • More acidity
  • Complex, lively flavours
  • Perfect for: Pour-over or filter coffee


Medium Coffee Roast

Medium roast coffee is roasted somewhere between light and dark. These beans will have a richer color than your lighter roasts, but won’t be as deep as dark coffee beans. Medium roasts are known for their smooth, balanced flavour. You’ll still be able to taste some of the coffee’s original characteristics, but with less acidity.

Pros:

  • Balanced flavour
  • Smooth body
  • Great for any brewing method
  • Dark Coffee Roast


Dark Coffee Roast

Dark roast coffee is roasted for the longest period of time, resulting in a coffee bean that has a dark brown colour (sometimes almost black). Dark roast coffees will also have oil on the surface of the bean. Since dark roast coffee is roasted for so long, much of the original flavour will be lost. Instead, dark roasted coffee beans tend to have a bolder, more intense flavour.

Pros:

  • Full body
  • Bold flavours
  • Low acidity
  • Perfect for: Espresso


Roast Levels and Caffeine Content

Many people will often assume that dark roast coffee has more caffeine than it’s lighter counterparts. This is a common misconception, as roast level does not actually affect the caffeine content of coffee. The reality is that there is almost no difference between the caffeine content of light, medium, and dark roast coffee. Lighter roasts may have slightly more caffeine per bean, but when measured correctly, the caffeine difference between light and dark coffee is minimal.


How to Pick the Right Roast for You

Now that you know the difference between light, medium and dark coffee roasts, how do you know which one is right for you?

If you’re just starting out, consider what you like to see in your coffee. Do you prefer bold and intense flavours? Try a dark roast. Enjoy brighter, fruitier notes? Try a light roast! Coffee roasts can taste drastically different depending on how they’re brewed, so you may want to experiment with different brewing methods as well.
