How to make the Strongest Coffee?

Everyone may be able to make coffee, but not everyone can make great coffee. The making of top-notch coffee might seem complicated. However, it isn’t! You only have to carefully learn the approach. Coffee making would become easy for you every time.

The article seeks to show you how brewing methods (see our coffee brewing guide for the best coffee) affect caffeine extraction and how you can make a great coffee and. It would be useful for you as a coffee lover or as a coffee business owner who desires to give his customers the best of tastes. You can always have coffee brewed to your taste (using the highest quality beans).

What Makes a Great Cup of Coffee?

According to experts, there are two major ingredients that make the flavour of a brew. The first one is the origin of the beans and how the beans were grown; that is the terroir, like in wine. The other one is how darkly or lightly the beans are roasted.

When it comes to roasting, experts say there is no right or wrong to it. It all comes down to personal preference. Everyone has something they prefer and that is what influences the kind of roast that they go for.

What's the Science Behind making strong coffee from the coffee beans

First things first, you need to know what caffeine is and how it is produced. Caffeine is the name of the natural stimulant found in coffee beans (check out our coffee beans gift sets). Caffeine is also naturally found in other plants like cocoa and tea leaves. In its natural state, caffeine is produced by these plants to help them deter pests. This is why coffee beans from higher altitudes with little pest problems have lower caffeine content.

The process of roasting has little or no effects on the caffeine content in a coffee bean. However, the density of coffee beans reduces during roasting. Therefore, coffee beans that are roasted for long hours tend to be lighter in mass and less dense.

That means if you have coffee grounds of the same mass, more coffee went into the production of the dark roast than you have in the light roast. This is why dark roast coffee tends to taste toastier and richer than light roasts.

Coffee Beans Brewing Methods and their Caffeine Content

The following are some of the best methods for brewing coffee beans.

French Press

French press is one of the simplest methods you can use to brew a strong cup of coffee. At the same time, it produces the highest level of caffeine per cup. Ideally, a 4oz cup of coffee from the french press produces between 80 and 100 milligrams of caffeine. That level of caffeine is the highest.

Using the French press method, the flavours and compounds in the coffee beans are extracted aggressively due to constant infusion in hot water. More so, you get caffeine of higher concentration when you steep the grounds for a longer time.

However, ensure that you do not over steep the grounds as that can make your coffee taste bitter.


The Aeropress method is for those who are always on the go. The method uses air pressure to push brewed coffee through a sieve. Using this method, you can produce between 50 t0 70 milligrams of caffeine from a 4oz cup of coffee.

The brew from this method is usually smooth, rich, and not too strong because of its lower levels of caffeine. If you want a more concentrated cup of coffee, you might want to steep the grounds for a longer time. That is, increase the brewing time from the recommended 30 seconds.

Filter Coffee

The filter coffee method usually comes in two forms. There is the drip coffee method and the pour-over method. Either way, you need a medium to fine ground to extract the coffee flavours slowly as water flows through the grounds.

A 4oz cup of coffee brewed with this method should contain about 60 to 100 milligrams of caffeine. Note that, using water with higher temperatures and finer grounds will give you better caffeine extraction.

Coffee Machine

Espresso coffee is the perfect coffee drink for people that need high doses of caffeine to push through their day. Unfortunately, due to differences in serving size, the quantity of caffeine from the espresso using this brewing method is lower than others.

A single 10z shot of espresso brew extracted using a coffee machine will have between 30 and 50 milligrams of caffeine. So if you need one of those caffeine hits, try an espresso.

A single 1oz shot of espresso extracted from a coffee machine contains 30 to 50 milligrams of caffeine. So if you need a caffeine hit, a double espresso shot might do the trick.

Decaffeinated Coffee

People usually think that decaffeinated coffee has no caffeine. Sorry to disappoint you, a cup of decaffeinated coffee has between 2 and 4 milligrams of caffeine. However, those levels are caffeine is too low to cause any side effects. Therefore those who need to abstain from drinking coffee can take decaffeinated coffee without seeing any adverse effects on their health.

Decaffeinated coffee, like any other coffee, brews well irrespective of the brewing method you use.

Steps in Making a Great Cup of Coffee

There are various methods of brewing coffee. None of the methods matches up to the making of a coffee using an Espresso machine. As a result, this article will show you the four steps involved in making coffee using an Espresso machine;

●       The Grind Stage

The first step in making a coffee using an Espresso machine is the Grind stage. This stage is very important as it determines how creamy your coffee will be. An overly coarse grind will result in a weak and watery coffee. You must watch out for the situation of the grind before grinding.

The grinding process requires you to first try out the grind with a little coffee to see if it is in good condition. If the grind is okay, the result will be golden and creamy coffee. When you get a pale-looking, watery, and weak cream coffee, your grind is not in the best condition.

●       The Extraction Stage

The extraction process is the next after the grind stage. Extracting your coffee should take between 25 and 30 seconds. It however depends on the condition of the grind.

If you realized that the extraction takes less than 20 seconds. This indicates that your grind condition was coarse. As such, it will produce a coffee with little or no cream.

If the extraction process takes beyond 30 seconds, then your grind was too fine. The result is going to be a coffee with dark and uneven coffee cream. You must therefore seek to ensure your grind is in good condition. Also, the extraction process should not go beyond 30 seconds.

●       The Milk Steaming Stage

The milk streaming can be done through the stretching and spinning method. However, we will be considering stretching as the best for this process. The stretching method requires the use of a steam wand and a thermometer.

You will have to stir the already-in-the-jug coffee with a steam wand. The wand must not be too deep down to the bottom of the coffee. The position of the steam and must be partially immersed to give room for air in the coffee.

As the heat comes up, the coffee begins to expand. When the coffee expands by 1.5 times its original volume and the temperature has increased by 25°C. You can then begin to spin your coffee.

●       The Pouring Stage

Before pouring, give your coffee a little swirling so as not to separate the milk. This ensured that milk did not break the cream while pouring. By so doing, it will help maintain the same flavour in every sip of the coffee.


Making the best of coffee can be done with an espresso machine. However, you must engage in the practice over and over to gain mastery. Only then can you produce a great coffee for yourself and your customers.
