Most coffee lovers have a preference: light roast or dark roast. Some people can go either way. Regardless, we thought we would highlight the features of light roast vs. dark roast to show you the difference. Not confined to just taste, there are quite a few variations between the two options. Today let’s talk about light roast vs. dark roast.
Roasting
Light roast beans are heated for shorter time periods and at lower temperatures than dark roasts, reaching a temperature between 385 degrees and 410 degrees. Beans will pop at 385 degrees, AKA the “first crack”, and this signifies that the beans have attained a light roast. They will then need to be cooled down.
Because lightly roasted beans are not left on the roasting machine for quite as long as dark-roasted beans, more moisture stays in the bean, which gives you a denser coffee. Light roast coffees, characterized by their light brown color, lack oil on the surface, giving them a light body.
Dark roast coffee beans remain on the roasting machine for a longer period of time and at a higher temperature than their light roasted counterparts. To be dark, beans must be roasted to a temperature that is higher than 430 degrees. During this time, the beans lose more moisture, resulting in a less dense coffee.
Dark coffees, characterized by a dark brown oil that glosses over the surface, have a robust, full body. Usually featuring a bold, smoky taste, dark roast beans have deep yet simple flavors because some of the initial flavors are lost or changed as part of the roasting process.
Dark roasts have a “second crack”, announcing that they must head to the cooling tray. This is when the oils appear on the surface of the bean, providing a bolder and richer flavor.
Flavor
The roasting process is what makes coffee beans light or dark, not the growing process. Light roast coffee has brighter, fruitier notes, as the beans aren’t roasted at very high temperatures, which is what allows these notes to remain intact. With dark roast coffee, oils are released onto the beans during the roasting process, adding to the flavor. Usually this results in a smokier flavor thanks to the high temperatures.
Light roast coffees are usually more fruity, crisp, acidic, or floral. Conversely, dark roast coffees are more smoky, bold, chocolaty, nutty, and robust.
Caffeine
You may assume that dark roast coffees have more caffeine in them but they actually contain less caffeine than their lighter cousin. While the beans themselves are no different in caffeine content, dark roast beans expand with the roasting process. So, if you measure in volume, you will probably get fewer beans per scoop, meaning that with lighter roasts, you get slightly more density of beans to caffeine.
In a nutshell, the difference in light and dark roast coffees when it comes to caffeine is small.
