What to know about pre-roasted coffee/ The Roasting Processes
We appreciate the science of roasting coffee. Roasting brings out the aroma and flavor locked inside the raw coffee beans.
Raw coffee beans are green and nothing like the roasted ones. They smell grassy and are soft and spongy. They are denser than the roasted beans because the moisture is still intact before the roasting process.
Roasting causes chemical changes in the beans. Coffee beans begin to darken as they absorb heat, whereas the hues differ depending on regions. The caffeine level in the beans also changes after roasting.
The three most common coffee roasts are referred to as light, medium and dark. They are roasted at different temperatures for a different time.
A freshly roasted batch contains the best flavors. Brew those crunchy beans while they are new and fresh.

Body & Complexity
Body refers to the physical properties such as texture, mouth-feel and heaviness of coffee. Weight and volume get altered in the roasting process.
Light roasts are brighter in color and have a thinner body. Since they see less heat, they have more moisture.
Dark roasts have a black hue. They have more body due to the caramelized sugar from the beans. Dark roast has a more robust and bold flavor. The beans get thinner in the roasting process.
More heat exposure caramelizes the sugar inside the coffee beans and gives it a bittersweet taste. Since light roast is not cooked for a long time, the original flavors are retained.
Light roast is often preferred for its embodiment of regional and original flavors. They have a sophisticated taste ranging from fruity tang to citrus.
On the other hand, dark roast loses the original beans’ flavor and is masked with roasts’ flavor. They tend to have a bittersweet chocolate flavor.
However, you may notice more differences in light roast vs. dark roast taste by trying these in different beverages such as cappuccino and espresso.
When we talk about the acidity of coffee, we mean the taste profile. Not the PH level.
Lighter roast coffee has the highest acidity. The compounds cannot be broken in less heat exposure. If you like you a punch in your cup, this is the roast for you. However, they can be trouble for your sensitive stomach.
The longer roasting process kills the acidity in the dark roast. Hence, it has fewer chances of upsetting your stomach. This lower acidity makes the dark roast pair perfectly with dairy products.
There is a myth of dark roast coffee being more caffeinated. However, the roasting period affects the caffeine content in beans. Light roast has higher caffeine content for shorter cooking time.
On the contrary, the dark roast contains less caffeine. Caffeine is usually burned off in the long roasting process.
However, the roasting process plays a little role in caffeine content change. Caffeine stays chemically stable throughout the process. The changes in density and size of the beans change the caffeine level.
If the need of more caffeine, go for the light roast. For cutting down caffeine, you can always switch to decaf.
The Roasting Difference
The significant difference is the roasting time. Water gets out in through evaporation in roasting. The longer you roast, the darker beans you get. Roasting brings out the complex flavor of the coffee.
Light roast is roasted till the first crack at a comparatively low temperature. Hence, a lighter roast is easier to achieve.
The dark roast is roasted till the end of the second crack for a higher temperature. You need to monitor the temperature to prevent any accidents. Moreover, a burnt bean will not be a fun flavor to drink.

However, light roast for its higher acidity can be a bit troublesome for your stomach. Dark coffee is safe to consume for the ones with a sensitive stomach.
