If you’re new to using this type of coffee maker, don’t worry. As brewing methods go, the French press is inexpensive and easy to get the hang of – they consist of just a carafe and plunger.
Despite the French getting a name check, the current design was patented in 1929 by two Italians – Attilio Calimani and Giulio Moneta. This design is still used today.
But, digging into the origin of the French press coffee maker will take you back to 1852 when the first documented evidence is found. At this time, a simpler version held the patent: the brainchild of two Frenchmen – Mayer and Delforge.
Since then, the French and Italians have argued back and forth over who can call it their own. But, wherever it started, its popularity has grown around the world thanks to the easy, delicious flavor.
Around the world, you may hear the French press coffee maker referred to as la / a cafetière, coffee plunger, or coffee press. But they all mean the same thing.
How Many Cups?
One of the main factors in choosing your French press is the size. You can choose anything from a single serving up to large vessels suitable for entertaining.
Too small and you will spend all your time waiting for your coffee to steep. Too big and you are left with too much coffee for one sitting (yes, it is possible to have too much coffee).
When looking at the sizes of coffee press’ (and other types of coffee maker), it can often be confusing by quoting either in ounces or cups. For example, a 12oz coffee press will be advertised as a 3 cup size. But this refers to a traditional coffee cup (tasse à café) which is 4oz. Generally speaking, 12oz is the size of a standard mug – so 12oz is a 1 person French press.
Luckily, they aren’t too expensive so you can have more than one in different sizes.
What is it Made of?
The body of your French press carafe can be made of a range of materials with little difference in quality. So, pick one that suits your aesthetic best.
Borosilicate glass (heat-resistant) or plastic gives you a view of your coffee and are generally the more affordable options. But whilst glass will be of higher quality, it won’t stand up to being dropped on the floor like plastic will.
On the other hand, stainless steel or even the less common ceramic provides better heat insulation. So, your coffee will stay warmer for longer (especially if it’s double-walled stainless steel) – but you will pay more for the privilege.
How Good is the Filter?
The filter is part of the plunger and is a vital part of your French press coffee maker:
It is made up of three stainless steel fine mesh layers. You want these to fit tightly to the walls of the carafe. If it doesn’t, you will end up with an unpleasant cup full of coffee grounds.

Where the French press differs from other brewing methods is its versatility. So, unlike espresso which needs specific espresso beans, when making French press coffee you can opt for any kind of roast from any region that you like. It’s a great exploration of coffee: try different regions and different degrees of roasted coffee beans to find your perfect brew.
The only thing to be aware of is ensuring your coffee beans are being ethically sourced. As a consumer, it’s important to ensure fair wages are paid to the farmers and that there is an emphasis on environmental sustainability. This transparency is more common when buying specialty coffee beans.

Ground coffee starts to lose its flavor 15 minutes after grinding. So pre-ground coffee will never have the same exciting coffee flavors as freshly ground.
When it comes to using a French press, you want coarse ground coffee so your grinder needs to be set towards the coarsest setting. For ideal extraction, the grind size should be about the size of kosher salt crystals.
If you go too fine, the grounds will slip through the mesh filter and leave you with a rather chewy cup of coffee. Or, if you have a poor-quality grinder, you will end up with uneven grounds, coffee bits getting through the filter, and a shoddy cup of joe.
From the different types of coffee grinders available, your best bet is to choose a burr coffee grinder.

You may see a golden ratio expressed as something between 1:11 and 1:17. This works by splitting your brew up into ‘parts’ where 1 is the coffee and the second number is how many parts of water. But it all boils down to how strong you like your coffee.
We recommend starting with 2 tbsp of ground coffee for every 5oz of water (a little stronger than the traditional drip coffee brewing ratio). If this feels a little strong then dial back the coffee about 0.5oz at a time until it’s just right. Not strong enough, then up the amount of coffee.
To get to grips with the perfect French press ratio, check out our full guide:
Brewing temperature is crucial to get the right extraction from your beans.
The ideal coffee brewing temperature is 200ºF/ 93ºC.
We use a temperature-controlled kettle to ensure our water is at the correct temperature. But you can also use an instant thermometer like the kind you’d use to check the temperature of meat. Either option works to ensure you’re brewing at the optimal temperature.
As the temperature is a key variable, it’s important to pre-heat your French press. Otherwise, achieving the perfect temperature will be pointless when it hits a cold coffee brewer.
Timing is everything when it comes to extraction. Leave your coffee grounds steeping for not enough or too much time will result in under or over-extraction, ruining your fabulous French press coffee.
Your best bet is to use a timer rather than just guess how long your coffee has been brewing. Most people carry a timer in their pocket (a mobile phone), so you don’t need to buy any extra equipment.
The ideal time to brew French press is four minutes.
However, you may want to “bloom” your coffee grounds for 30 seconds in a small amount of water first for maximum flavor extraction.
The chemical makeup of your water will affect the final flavor of your coffee (we did warn you it was about to get geeky!)
To make the best coffee, you should avoid using distilled water as the lack of dissolved minerals will make a flat, flavorless cup. Filtered tap water or bottled mineral water is ideal for coffee extraction.
Time needed: 5 minutes
- Grind your beans: Set your grinder to a coarse setting and grind enough beans for the number of cups you are making. Our coffee ratio guide will help, but a good starting place is 2tbsp to every 5oz of water.
- Heat the water: Heat the water to 195-200ºF. If you have a thermometer or temperature-controlled kettle this will be fairly straightforward. But, if you are doing this “blind”, heat the water to boiling then allow it to cool for 1 minute before you pour over the waiting coffee grounds. Whilst you are waiting, add boiling water to the empty brewing chamber to keep the whole coffee maker hot throughout the brewing process.
- Let the coffee “bloom”: Add coffee grounds and an equal amount of water to the weight of coffee beans and wait for 30-45 seconds. The mixture will become frothy – this is the gases from the grounds escaping and is called the “bloom”. This stage is critical for making barista-level coffee at home, it transforms good coffee into great coffee.
After 45 seconds, stir with a wooden coffee stir stick like a bamboo paddle or chopstick.
- Pour the water: After you have stirred your coffee grinds, pour in the rest of your water and stir a little – but not too much.
- Steep your coffee brew: Place the lid on – but don’t press the plunger. Start your timer and aim for 3 minutes 30 seconds, so a total of just over 4 minutes with “bloom” time. This is the bit that will need some tweaking to get just right:
If your coffee is thin and acidic, steep for longer. If you find it too bitter, try reducing the steeping time. With a little practice, you’ll get this nailed down to an art form.
- Plunge and serve: Now that your coffee is perfectly extracted, press the plunger down and pour. If you have extra, fill a thermos flask so you can enjoy it later.
1. Freshly grind your beans – To start, you need coarse ground coffee. Use our coffee to water guide to help work out how much ground coffee you need, but a good place to start is 2tbsp (12 grams) of coffee to every 5oz of water (150ml). After grinding, pour the ground coffee into the brewing chamber.
2. Add the water – The joy of making cold brew coffee is that you don’t need to pre-boil the water. Instead, room temperature water is perfect. Once added, stir with a wooden coffee stir stick like a chopstick.
3. Steep in the refrigerator – Place the lid back on but don’t press the plunger. Then place your French press in the fridge overnight.
4. Remove, plunge, and enjoy – When you wake in the morning, all that’s left to do is remove your press from the fridge and push down the plunger. Now you can enjoy your cold brew, French press coffee.

Your French press isn’t like a wok which gets seasoned over time. Instead, those leftover coffee grinds and oils are taking everything you’ve learned about how to brew French press for delicious flavor and pouring it down the sink.
Luckily it couldn’t be easier to clean, just follow this step-by-step guide:
1. Let it cool down – At the risk of sounding like your mum, please don’t try to burn yourself. Instead, let your coffee maker cool down whilst you enjoy your brew and come back to the cleaning invigorated from the caffeine.
2. Empty the coffee grounds – To avoid a call to your soon-to-be-upset plumber, don’t pour the grounds down the sink. This will result in blocked pipes. Instead, add a little water to the carafe, swirl it around, and pour the water and dislodged grounds into a mesh sieve.
To minimize any waste going down the pipes, rinse the plunger off over the sieve too. Luckily, coffee grounds can easily be recycled.
3. Rinse and scrub – Add some warm water and dish soap then pop the plunger back in and plunge a few times to remove some of the coffee stains and oils. Then take a sponge or brush and thoroughly clean the carafe and plunger separately. Take care around the filter.
If there are any stubborn stains, use baking soda and a brush.
4. Rinse and dry – Thoroughly rinse your French press to prevent any soap from getting into your next brew. Dry and get ready to make your next French press coffee.
The main mistake people make is the size of the grounds. If your grind is too fine, it will cause over-extraction and very bitter coffee.
To help, most grinders will tell you the range you should use for French press. And, although it may need slight tweaking depending on your own preference, it should only take a couple of tries to get it exactly how you want it.
Of course, if you use pre-ground coffee, the size will already be right. But you’ll never get the same great coffee flavors as freshly ground delivers.
It is surprisingly simple to burn coffee grounds and something that’s best avoided to save you from a bitter, burnt-tasting cup of joe that will be oh so disappointing. So, to save you from the depths of despair, don’t pour boiling water onto your delicious, freshly ground coffee.
When you’re in need of coffee and waiting for it to brew, it can be tempting to plunge too early.
Avoid that temptation.
You’ll soon regret your impatience as you sip on acidic, thin, under-extracted coffee.
But, the opposite is also true: If you walk away and leave your French press coffee brewing for way too long, you will be equally disappointed. The result is a very strong but insanely bitter coffee that is offensive to everyone who worked hard to bring you those excellent French press coffee beans.
With this brewing guide at the ready, we hope you will no longer be left wondering how to use a French press. All that’s left for you to do is choose your coffee maker and beans. Then, get to work making your perfect brew.
