If you love coffee, then you’re likely to know that it’s roasted to various levels. Each roast level results in different coffee tastes.
If you’re wondering why your favorite cup of coffee has a unique taste depending on the roast used, or you want to learn how to choose the best roast for your taste preferences, then you need to learn more about the differences between dark and light coffee roasts. Read on to find out.
Facts about Dark and Light Roast Coffee
Fact #1- Dark roast has slightly less caffeine than light roast
Most people assume that dark roast has more caffeine. However, light-roasted beans contain a little more caffeine content than dark-roasted beans. However, the difference in caffeine content is negligible.
Fact #2- Full coffee flavors are more prevalent in light roast
Coffee contains at least 800 flavor and aromatic compounds. You stand better chances of experiencing these flavors when taking coffee brewed with light roasts.
Fact #3- Dark roast is typically blended with low-quality coffee beans
Coffee beans are often over-roasted as a technique of masking any unappealing flavors. As a result, many coffee roasting companies try to make savings by blending low-quality coffee beans with dark roasts. However, not all coffee roasting companies cut corners. Thus, make your choices carefully when shopping for dark roast coffee beans.
Coffee Roasting Process
Coffee is grown like a fruit. The flavor profile, depth, and quality of coffee beans are mainly determined by soil composition, altitude, growing conditions, harvesting, and the processing method used.
There’re at least 50 coffee-producing countries today, with each country having its unique coffee growing conditions. Thus, each country boasts of producing unique coffee. As a result, you can only have the tastiest coffee experience by taking single origin coffees.
When shopping for coffee but you’re not sure of the brand to choose, coffee labeled as “single source” will be your best choice. If a label on a coffee package indicates that it originates from several countries, then you won’t get the best experience that coffee has to offer. A coffee brand with a label indicating that it’s sourced from different countries means that it’s a coffee blend, such that low-quality beans are blended with dark roast to give it a bolder flavor. However, subtle flavors are muted.
Once coffee is harvested, processed, and delivered to roasters, the green beans are roasted at a temperate of between 356 and 440 degrees Fahrenheit. The exact roasting temperature depends on the kind of roast needed.
In most cases, the roaster starts with experimentation by roasting the beans at different levels such as light, medium, and dark roast. Experimentation allows the roasters to determine the coffee roast that gives the best flavor. Since every type of coffee is unique, roasters repeat this process for each type of coffee they’re working with.
Finding the Best Coffee Roast
The main difference between dark and light roast is their flavor. You can learn more regarding how different roasts affect coffee taste by knowing their different flavor profiles. That way, you’ll stand better chances of choosing the coffee you’ll love.
However, it’s worth noting that there’re standards for what makes up a dark or light coffee roast. Thus, your experience can vary from one roaster to another.
For the purpose of this guide, assume light roast beans have a dry surface and light brown color whereas dark roast has a slightly oily surface and brown to dark color. Medium roasts are somewhere between dark and light roasts.
- Dark Roast
It’s defined by nut, caramel, and chocolate flavor notes. Most top-quality coffee beans aren’t roasted to a dark roast. The reason behind this is that dark roast masks most of the natural coffee flavors in top-quality coffee.
However, dark roast features a heavy body and low acidity, with notable nutty and chocolate flavors. Regardless, dark roast is delicious when roasted properly. It’s even sweeter if it contains cream or latte made with espresso.
Unfortunately, most roasters over-roast dark roast, thereby resulting in oily and blackened beans that don’t have much flavor left. Over-roasted beans have a bitter and burnt taste.
If you want the best of dark roast, choose a coffee bag labeled single origin. Single origin coffee is an indicator that the coffee beans aren’t over-roasted. They’re only dark enough for a heavy-bodied and smooth cup of coffee, just the way some coffee drinkers like it.
- Medium Roast
High-quality beans are often roasted to a medium roast to give them more body. Also, a medium roast makes the coffee have a balanced taste.
If medium roast is done well, you’ll enjoy flavors that make each type of coffee special with less acidity and extra sweetness. Overall, medium roast is defined by caramel, citrus, and berry flavor notes.
- Light Roast
Essentially, top-quality coffee beans are sold as light roast coffee. The reason behind this is that light roasts make it possible for the full natural spectrum of flavors to be felt most. Thus, the uniqueness of a specific type of coffee can be best defined with light roast coffee.
With light roast coffee, expect to get herbal, floral, and fruity notes with less body, and bright acidity.
Consider Your Brewing Method
The kind of brewing method you use can affect the resultant flavor of the brew. If you’re brewing with light roast, preferably use the pour over method to enjoy all the flavors that come with a light roast. Use a French press for a darker roast.
