Types Of Roasts, Coffee Roasts Explained

Getting to know the different types of roasts can seem a little complicated, French roast, Italian roast, full city roast, Espresso, medium roast and so on.

What are they and what do they mean?

In this article I fully explain what the different coffee roasts are with the goal of helping you to understand the different roasts and how they affect the taste of your coffee.

Pardon the pun, let’s get cracking!

What Does The Roasting Process Do?

The coffee roasting process turns the seed of a coffee cherry from a green, earthy bean with a grassy smell into the coffee beans that we are more familiar with that result in the cup of coffee that we enjoy drinking.

The coffee roasting process takes those coffee beans, toasts them, changing their color to a predetermined darker color giving them caramelized flavors and chocolatey and nutty notes.

Roasting causes numerous chemical changes and reactions to occur which turn those seeds into the beans that can be used for making a cup of coffee. The roasting temperature and roasting time play an important role in what the end result will be.

At higher temperatures, the coffee oils appear as a shiny surface on the beans. At 401F (205C) expand and crack for the first time, known as the first crack. At 437F (225C) the second crack occurs.

If you are home roasting, never roast your high quality coffee beans at a temperature above 482F (250C). Beyond that temperature, your beans will just become burnt, and end up with a full on charcoal ash like taste.

Unfortunately, there is no standard universal naming of roasts or descriptions in the coffee industry. However, with a keen and trained eye, you will be able to identify the different roast levels by their color.

What Are The Different Coffee Roasts? Different Coffee Roasts Explained!

I’ve been emailed and PM’d on social media few times asking me what the three roast level of coffee are. There are actually four main roast levels with many more roasts within those levels.

I seriously wish that there was some kind of universal regulation on roasts and names!

What Are The Three Roast Levels Of Coffee?

Addressing the question I get asked a lot. Strictly speaking, there are three roast levels, which are light roast, medium roast and dark roast.

However, there is a very common fourth level that is a bridge between medium and dark named, imaginatively, medium dark roast.

The Different Coffee Roast Levels

Let’s get to the meat and bones of this article and talk in more detail about the different levels of coffee roasting and what they are and what they mean exactly.

Light Roast Coffee Beans

This is the first of the four types of coffee roast and are roasted for the shortest period of time and at the lowest temperature. The internal temperature of lightly roasted beans is within the 356F to 401F (180C to 205C) and are roasted until the first crack.

The coffee oils are still locked inside the beans and have not yet come to the surface to coat the beans. Light roast coffee beans are easily identifiable as the lightest of all roasts and their non-oily surface.

Light roasts have a greater caffeine content and are more acidic than the other coffee roasts as the roasting process pulls out the caffeine. As you up the roasts from light to dark, the caffeine level as acidity levels drop slightly.

Due to being roasted at a lower temperature and for a shorter period of time, this roasting process does not have as many chemical reactions and changes happening inside the beans. This leaves all the origin flavors are still in the beans, waiting for you to brew them out and into your cup of coffee.

Cinnamon roast, half city roast and New England roast and blonde roasts are all light roasts.

 Medium Roast Coffee Beans

Medium roasted coffee beans are roasted to an internal temperature range of 410F to 428F (210C to 220C) and beyond the first crack and before the second crack. The typical American coffee drinker is most familiar with this roast. They are less acidic than a light roasts and have less caffeine.

A medium roast has slightly more body and is a middle of the spectrum roast. Your speciality single origin beans can also be roasted to this level also without losing too much of their flavors.

City roast, American roast and breakfast roast are examples of medium roasted beans.

Medium Dark Roast Coffee Beans

Medium dark roasted coffee beans are roasted to an internal temperature range of 437F to 446F (225C to 235C). This roast is taken to the point of the second crack or slightly after it. This level of roast has a semi oily surface as the coffee oils are only starting to come to the surface of the coffee beans.

This type of roast, as a result, has a fuller flavor that is deeper, richer and less acidic. A common and popular medium dark roast coffee blend is a full city roast and Vienna roast.

Dark Roast Coffee Beans

The dark coffee roast is perhaps the one that you are most familiar with. The roasting temperature for this roast is typically from 464F to 482F (240C to 245C). A dark roast is easily identified with its dark color and shiny surface due to the oil on surface of the beans. This type of coffee bean has none of the origin flavors as they have all been roasted out during the roasting process.

You can expect richer, sweeter, more full-bodied flavours with less caffeine and less acidity than all other coffee roasts. The darkest of the dark roasts is a French roast which has a smoky, deep, deep, almost ash like burnt flavor.

Italian roast, espresso roast, and Turkish roasts are all popular dark roasted coffee beans.

What Do The Different Coffee Roast Levels Taste Like?

Since I have already touched on the main difference between coffee roasts and the flavor profiles I’ll simply summerise what you can expect with each roast:

  • Light Roast: Expect a clear, bright mild cup of coffee with a pronounced acidity and the origin flavors of the beans.
  • Medium Roast: Expect a slight sweetness and aroma, and a nice balanced coffee.
  • Medium-Dark Roast: Expect a reduced acidity, heavier body and more chocolate like notes.
  • Dark Roast Coffee: Expect a full bodied coffee with smoky taste and more pronounced dark chocolate notes.

Naturally this is only a guide to how coffee should taste at each roasting profile. The end result will vary depending on your coffee beans and how fresh they are as well as other aspects.

How Does Roast Affect Coffee Taste?

The roasting of coffee beans is one of the biggest factors in coffee taste. Few things influence the taste more than roasting.

The roasting of green coffee beans transforms the green beans from something that simply cannot be used to make any drink, let alone coffee due to a rather grassy taste, to a delicious and tasty flavorful coffee.

Roasting to different levels does a lot more than just giving the beans a different color. They change their attributes and taste significantly.

Coffee Roast Levels And Caffeine

The relationship between the coffee roast level and caffeine content is not something to be focused on at all as the difference is insignificant. Sure, there is a difference.

The difference between a light roast, a blonde roast espresso for example and a dark espresso roast is only 10 mg.

The lighter the roast, the more caffeine it contains. However, how much caffeine is in your cup of coffee, other variables, such as your brewing method, have a greater effect.

Coffee is love, it's more than love — it's a passion of mine. I've had the luck to have travelled and enjoyed the most exotic of coffee's and unique flavors, brewing methods and techniques of making the perfect coffee from Thai hill tribe coffee to Indonesian volcanic coffee, Malaysian coffee that comes in a tea bag and the array of flavors in Vietnam, from Vanilla to Orange to Coconut to Avocado to even salt coffee and the famous egg coffee. The best part of my coffee adventures is getting to mix with the locals over a nice brew and learning how they make it! I'm cited and referenced on Google Scholar for the topic of coffee.
