Depending on your personal taste, you may like a light or dark cup of coffee. For some, the bitterness of the dark roast is to their taste. They find it has more caffeine than the light roast.

For others, the bitterness of the dark roast is not to their taste and they prefer the taste and smell of a light roast.

So, which one is right for you? Read on to learn more about coffee bean types and different tastes that go along with them.

What Is The Difference Between Light And Dark Roast Coffee?

The main difference between light and dark roast coffee is the amount of acidity/esterase in the beans. Acidic coffee has a higher level of carbon dioxide and can produce a more acidic taste in your cup of coffee. Light roast coffee is typically less acidic than dark roast coffee. With respect to the caffeine content, though, both light and dark roast coffee have about the same amount of caffeine.

The first giveaway that something is different between light and dark roast coffee is the amount of caffeine in these beans. While light roast coffee has 11% more caffeine than dark roast coffee, dark roast coffee has 15% more caffeine. Next, notice the grind. If the grind is different between the two coffees, you’re likely going to get different tastes and aromas in your cup of coffee because of this. If you buy a medium- to light-roast coffee, you’ll likely get a dark roast in a medium- to the dark-cup-size coffee maker. If you go with a medium- to medium-dark roast coffee, you’ll likely get a “light” taste in your cup of joe.

Which Has More Caffeine?

When it comes to the caffeine content of coffee, there are several factors to consider. Does the coffee come from a light or dark roast? If you’re looking for the most caffeine in your cup of joe, go for dark roast. However, if you’re a light-roaster—and want to keep your caffeine level up—then go with light-roast coffee.

There’s more caffeine in the darker-roasted coffee than there is in the light-roasted variety. This isn’t something you should take lightly; the least dense and most energizing kind of coffee is the dark roast. It has far more caffeine than light roasts.

In fact, a medium-dark roast has nearly double the concentration of caffeine than a light roast. The amount of caffeine depends on how much sugar has been added to it during its processing.

The difference between these two coffees is subtle—not enough to Instagram your cup of joe with an exact dose, but enough that you might want to consider which one you’re drinking instead. Think twice before drinking the other guy’s poison.

Why Is Light Coffee More Caffeine-packed Than Dark Coffee?

There are a few main reasons why light coffee is more caffeine-packed than dark coffee. First, the enzymes in coffee break down the caffeine in the coffee bean much more quickly than dark roast coffee. Therefore, while light roast coffee has 8 times more caffeine, it takes less time for the caffeine to reach your coffee cup after it’s been roasted. Second, because light roast coffee is less expensive, it has to come in a smaller package because you don’t have the chance to store it at a higher temperature. Third, because it’s less expensive, retailers can sell you a smaller amount of coffee to get the same amount of caffeine in the cup so you don’t get as much boost from the price increase.

Dark Roast Coffee Has More Tannins Than Light Roast Coffee

Coffee has a high level of acidic compounds called acids that form when oxygen gets to certain parts of the bean. The more intense the coffee acidity, the more pronounced the “tannin” taste in your cup of coffee. And because dark roast coffee has more tannins than light roast coffee, you get a stronger “tannin” flavor in your cup of java. If you love strong coffee, but don’t necessarily love the taste of strong coffee, you may want to try a dark roast. If you’re worried about acidity and want to keep your caffeine intake low, go with a lighter roast.

When Is Lighter Roast Coffee Better Than Darker Roast Coffee?

If you’re mainly interested in the caffeine level, go with the lightest roast possible. If you like stronger coffee, though, go for the darker roast. The darker the better for a dark roast coffee because the levels of acidity in the beans are higher than the lightest roast coffee. If you’re really in the mood for a strong cup of coffee, though, go with the darkest roast you can find. Although the lightest roast is usually the most popular choice for coffee shops, dark roast coffee has a higher caffeine content so you might want to stick with that if you want a stronger caffeine hit.

How to Choose a Coffee Bean?

The type of coffee you buy will largely depend on your preferences. If you like your coffee strong, it’s probably best to go with a darker roast. If you’re more of a light drinker, though, you may find that a lighter roast is better for you. Regardless of your preferences, you can learn a lot about coffee by looking at the level of acidity in the beans. If the acidity is very low, the coffee is said to be “light.” The acidity is the “tonic” value of the coffee and is said to give your coffee body and flavor. Anything with a low tonic value is considered light in taste.


While there are many variables that go into determining the caffeine content in coffee, one factor that many people consider is the roast of the coffee. Depending on your preferences, you may find that light or dark roast coffee is better for you than other types of coffee. But regardless of which flavor you like best, the only way to know for sure is to try them both and see what you like better. Keep in mind that the taste of coffee is dependent on many different factors such as the quality of the water, the soil, and the type of beans. Each of these factors is different between coffee crops and can affect the taste of coffee beans. So, whether you’re a light or dark coffee drinker, you can opt for the highest-quality beans to get the most out of your cup of joe.
