What Method Makes The Strongest Coffee?
Whether you are into coffee or not strength in coffee is a bit of a talking point.
I think it’s because what is sometimes described as strength in coffee may not always be what you think.
It could be for example the amount of caffeine in the coffee or the taste of a particular brewed coffee or even the concentration of dissolved coffee in a volume of coffee.
Regardless of how we quantify strength, we will guide you through which method makes the strongest coffee.
What makes the strongest coffee?
Although there are different angles and perceptions of strength in coffee a short answer is espresso makes the strongest coffee overall.
From a combination of caffeine content, taste and concentration.
However it is important to remember that there are many factors and variables that are present when brewing or extracting coffee which may lead to an increase in strength.
Caffeine content in coffee between brew methods should roughly be the same throughout, if the coffee is extracted properly.
However, if you were to make a French press/Cafetiere and extend the brew time you will end up with a stronger coffee in all forms (caffeine content, taste and concentration of coffee).
Another factor that you have to take into account is the size of the beverage and it’s relative strength.
An espresso has roughly 50mg of caffeine whereas one cup of pour over coffee has roughly 130 mg of caffeine.
However you also have to take into account the volume of each cup as an espresso coffee is roughly one eighth of that of a pourover.
To conclude, the pound for pound strongest coffee is therefore an espresso.
Which coffee method has the most caffeine?
The most caffeine across all of the methods is a cafetiere/French press per serving.
However, when you take into account the volume of the servings the most caffeine is an espresso. Here is a list of the caffeine content of brew methods with their comparative serving volume:
Pour over or Filter, 8-ounce serving — 95 - 160 mg caffeine
Cafetiere/French press coffee, 8-ounce serving — 90 - 130 mg caffeine
Espresso, 1-ounce shot — 40 - 70 mg caffeine
Cold brew coffee, 12-ounce serving — 150 mg caffeine
Moka pot, 8-ounce serving — 70 - 110 mg caffeine
Aeropress, 6-ounce serving — 70 - 100 mg caffeine.
What type of coffee is the strongest?
There are a few ways to describe ‘type of coffee’.
For example: type of coffee beans, type of processing method, coffee roast type, brew type.
In a nutshell: A robusta coffee finely ground and over extracted in a filter coffee maker would make a pretty strong coffee.
Starting off with the type of beans, there are two main types Arabica and Robusta.
Arabica coffee makes up around 65% of the overall world coffee production, although it is harder to grow and produce than robusta it is highly prized for its flavour profile.
Robusta coffee is commonly used in espresso blends and adds body and depth.
Robusta coffee is also known for its higher caffeine content and is often used in coffee brands that showcase strong coffee.
Roast type also adds another parameter to the strength scale.

This time primarily on flavour.
A dark roast coffee typically has the same amount of caffeine as a light roast coffee (per bean rather than per volume - as darker roast coffee is less dense than light roast).
However, the flavour profile oof dark roast coffee is usually a stronger taste with roasty or smokey notes or dark chocolate.
Which coffee bean makes the strongest coffee?
Does a finer grind make stronger coffee?
A finer grind does not necessarily make stronger coffee, but it can result in a more concentrated and flavourful brew.
The strength of coffee is primarily determined by the ratio of coffee to water, with a higher ratio resulting in a stronger brew.
However, a finer grind can increase the surface area of the coffee grounds, allowing for more efficient extraction of coffee solids and oils during brewing.

This can result in a more concentrated brew, which may give the impression of a stronger coffee.
Strength of coffee can also be influenced by factors such as the roast profile, the brew method, and the brew time.
So while a finer grind can contribute to a more concentrated brew, it's not the only factor that determines the strength of coffee.
Is dark roast the strongest coffee?
Contrary to popular belief, the roast level of coffee beans does not necessarily determine the strength or caffeine content of the coffee.
Dark roast coffee beans are roasted longer and at a higher temperature than lighter roasts, which can give them a more intense and bitter flavor profile.
However, the caffeine content in coffee beans is largely determined by the type of bean, where it was grown, and the brewing method used.
For example, arabica beans typically have less caffeine than robusta beans, and the amount of caffeine extracted from the beans will also vary depending on factors such as grind size, water temperature, and brewing time.
So while dark roast coffee may have a stronger and more intense flavour, it does not necessarily mean it contains more caffeine than a lighter roast coffee made from the same type of bean.
The strength of coffee is subjective and can refer to both the flavour and the caffeine content, so it is important to consider both factors when choosing a coffee.
Does coffee get stronger the longer it steeps?
Coffee can become stronger in flavour the longer it steeps, but this depends on the brewing method used.
For example, in methods such as French press or cold brew, coffee is steeped for a longer period of time to extract more flavour from the beans.
In these methods, the coffee can become stronger in flavour the longer it steeps.
However, in methods such as drip coffee or pour-over, the coffee is typically not steeped for a prolonged period of time.
Instead, hot water is passed through the grounds quickly, and the flavour of the coffee is extracted in a shorter amount of time. In these methods, the strength of the coffee is determined by the amount of coffee used and the brewing time, rather than the steeping time.
It is worth noting that while longer steeping times can result in a stronger flavour, there is a limit to how much flavour can be extracted from the beans.
Over-extraction can lead to bitter and unpleasant flavours, so it is important to experiment with brewing times and techniques to find the optimal balance for your personal taste preferences.
