EspressoEspresso is a coffee brewing method in which a pressurized hot stream of water is passed over fine coffee grounds. Espresso is one of the most dense coffee drinks having 60 to 70 mg of caffeine per ounce.

Drip coffee: Hot water is dripped through a filter full of coarse coffee grounds in a drip coffee machine. The contact time between water and grounds is longer in drip machines than in espresso, but there is no pressure element. An 8 oz cup of drip coffee contains more caffeine than a single shot of espresso, which is around 65 – 120 mg.

Americano: Americano is usually prepared by pouring 4 to 6 ounces of water over a freshly brewed double shot of espresso.

Long Black: Americano and Long black are almost the same coffee drinks. In Americano, the water is poured over an Espresso shot, while in Long black, espresso is poured over hot water.

French Press: French Press is a unique manual coffee brewing method in which water is allowed to steep through coarse grounds for 4 to 6 minutes. After that, the coffee grounds are separated by the metal filter of the French Press coffee maker. An 8 oz cup of French Press can contain 100 – 137 oz of caffeine depending on steeping time and the type of coffee beans.

Latte and Cappuccino: Latte and Cappuccino are similar drinks; both have a layer of espresso shot at the base and layers of steamed milk and foam at the top. The only difference is Cappuccino has a 1:1 of milk and Espresso while Latte has 2:1 of milk and espresso. As Cappuccino is more denser, it has more caffeine content per ounce.

Decaffeinated coffee: Caffeine is eliminated from coffee beans using organic solvent and carbon dioxide. You can brew any type of coffee drink with decaffeinated coffee beans. Decaffeinated coffee beans will still have a small amount of caffeine, around 0.25-0.37 ounces.

Cold Brew: Cold brew coffee is brewed at room temperature for an extended period for more than 10 to 12 hours. It has smooth, less bitter, and chocolaty flavors. The usual serving size of cold brew is 16 oz which has a high amount of caffeine, up to 197-213 mg per serving.

Pour-over coffee: Pour coffee is a type of drip coffee prepared manually without any machine. Typically, the brewing process in a pour-over method is longer; that’s why it has more flavors and caffeine than coffee prepared through drip coffee machines.

Instant coffee: Instant coffee is made by brewing regular coffee beans in large containers. Then this brewed coffee is concentrated and condensed into small granules. Instant coffee is used to prepare coffee drinks quickly by dissolving the granules into water or milk. A typical 8-ounce cup of instant coffee can contain up to 60 to 80 mg of caffeine.

Turkish coffee: Turkish coffee is made in cezve by dissolving fine coffee grounds into water and milk. This is an unfiltered type of coffee drink; that’s why it has the highest caffeine content, up to 165 mg of caffeine per serving.

How much caffeine in a coffee bean | Arabica vs Robusta

According to research, most coffee beans have almost 10-12 mg/g of caffeine. And there are 6 to 7 beans in a gram, so there is 1.4-2 mg of caffeine in a single coffee bean.

Robusta coffee beans are richer in caffeine than Arabica beans.

On average, Robusta beans have 18-20 mg/g of caffeine, while Arabica beans have 8-12 mg/g of caffeine.

If you are a caffeine lover, you might be tempted to buy Robusta beans next time you go shopping. But Robusta beans are not liked by coffee enthusiasts all around the World. The reason is too much bitter taste of these beans. And also, Robusta beans lack the balance and complex flavors of coffee.

That’s why most people prefer Arabica beans over Robusta.

Robusta beans are mainly used for preparing coffee blends because 100% Robusta beans can be very unpleasant to drink.

What roast has the most caffeine | Dark Vs Medium Vs Light

Some people say there is more caffeine in dark roasts because they produce a stronger and more robust cup of coffee, while others may say that light roasts have more caffeine because the roasting process eliminates some caffeine.

Well, in actual, both opinions are wrong. The caffeine in the coffee beans remains the same throughout the roasting process.

During the roasting process, because of the high temperature,, most of the moisture content evaporates from the coffee beans, and the beans lose their weight and grow in size.

That’s why lightly roasted coffee beans have more caffeine content on a volumetric basis than dark roast because the same volume will occupy fewer coffee beans of darker roast than the lighter roast.

And on a mass basis, the dark roast will have more caffeine because the same mass of both the roasts will have more beans for the darker roast.

But if you measure all different roasts, bean to bean, there will be no difference in the amount of caffeine.

So, if you want to have more caffeine, there is one simple rule “Add more coffee beans to your cup”.
