Sep 28, 2024 · There is no research-backed conclusion as to which exact type of coffee is the healthiest. However, it’s possible to narrow down your options by eliminating sweetened lattes, very dark roasts (low antioxidant content), very light roasts (high caffeine content), and unfiltered coffee.

When it comes to coffee, most people have a drink of choice.
For some people it’s iced or frozen coffee, while for others it’s a hot espresso drink. For many, it’s as simple as a choice between a cup of light or dark roast.
You’ve probably heard people talk about the differences between light and dark roast coffee, and you could even have a favorite roast of your own already. Still, you might wonder about the differences between the two.
This article compares light and dark roast coffee by highlighting the differences in their caffeine content, health benefits, flavor profiles, and more.
Before they’re roasted, coffee beans are green fruit seeds of Coffea plants, with little resemblance in color or flavor to the morning beverage we all know and love.
Roasting these green coffee beans evokes a variety of chemical, physical, and sensory changes in the beans and is ultimately what gives coffee its quintessential color, aroma, and flavor (1).
Coffee beans are usually roasted in large rotating drums, in which they’re heated for 5–15 minutes before being cooled and packaged.
It sounds like a simple process, but even slight changes in the time and temperature at which the beans are roasted can result in differences in the final product.
Light roasts are typically roasted between 350°F–400°F (177°C–204°C) for around 10 minutes or less (2).
Dark roasts are heated for closer to 15 minutes above 400°F (204°C). Medium roasts fall in between (2).
Many of us reach for a cup of coffee first thing in the morning or when we need quick boost of energy. That’s because the caffeine in coffee stimulates brain activity and releases neurotransmitters that make you feel more alert and awake.
Therefore, you may wonder whether light and dark roast differ in terms of their caffeine contents.
There are misconceptions about which roast is higher in caffeine. Some people assume that the darker the bean, the higher the caffeine content. Others have heard that roasting burns off caffeine, meaning light roasts are actually higher in the stimulant.
However, dark roasts tend to be slightly lower in caffeine after the roasting process.
That said, recent and older studies alike suggest that the difference is negligible. As long as coffee is measured out by weight rather than by volume, the caffeine content between the two roasts is very similar (3, 4, 5, 6).
Because dark roast beans puff up with air and expand as they’re heated, measuring coffee by weight tends to be more accurate than measuring by volume, such as in teaspoons or tablespoons.
After caffeine, the other reason why people are drawn to either light or dark coffee roasts is usually the flavor.
Compared with dark roasts, light roasts tend to have more delicate but complex flavor profiles. Because some of the initial flavors of the beans are lost or altered during the roasting process, dark roasts tend to have deep but simple flavors (10).
Light roast coffee also tends to have a thinner mouthfeel than dark roast. The natural oils present in dark roast coffee beans increase the viscosity of the final product, which makes it feel thicker in your mouth.
Light roast coffee is often described as:
•bright
•crisp
Research has linked moderate coffee consumption — about 3 cups (about 710 mL) per day or less — to protection against Alzheimer’s disease, as well as associated it with reduced inflammation and better outcomes for those with type 2 diabetes (13, 14, 15, 16).
Still, many of these studies were based on observational results, which sometimes produce conflicting results. Therefore, more randomized controlled trials in humans are needed to determine coffee’s health benefits (17, 18, 19, 20).
Remember that many of the health benefits of coffee are contingent upon how much cream and sugar are added to the drink.
Nevertheless, it’s widely accepted that coffee contains bioactive nutrients, such as chlorogenic acid polyphenols, which may help with weight loss (21, 22, 23).
Older studies suggest that coffee also contains melanoidins, which may have a range of benefits, including reduced inflammation and antioxidant properties (24).
Though both light and dark roast coffees contain antioxidants and polyphenols, light roasts might be higher in these nutrients, as dark roasts lose somewhat more plant chemicals during the roasting process (2, 8, 25, 26).
The differences between light and dark roast coffee result from the length of time the beans spent roasting and the temperatures they reached.
Light roast coffee beans are heated to a lower temperature for a shorter length of time than dark roast beans.
While there are some slight differences between the two, both types of beans contain plenty of caffeine, healthy nutrients, and delectable flavors.
Whether you should drink light or dark roast coffee is a matter of personal preference.
Various types of coffee roasts, beans, a plethora of flavors—and for the coffee newbie, the sheer variety can be overwhelming. In that regard, one of the first important things to know for any new coffee consumer will be light roast vs. dark roast. What's the difference, and does it really matter?
