How Much Coffee Per Cup Your UK Brewing Guide
For a standard cup of coffee, your best starting point is what we in the industry call the "golden ratio": 1 gram of coffee for every 15 to 18 grams of water. This works out to be around 15 grams of coffee for a typical 250ml mug.
Unlocking Your Perfect Cup with the Right Ratio
The secret to a truly brilliant brew isn't some complex, hidden formula. It’s actually a simple, reliable starting point that professional baristas trust every single day. Knowing exactly how much coffee to use per cup removes all the guesswork and sets the stage for a consistently delicious result. Think of this ratio as your faithful foundation—a launchpad for your personal brewing journey.
Coffee is more than just a drink; for many of us, it's an essential part of our daily rhythm. It’s no surprise that an incredible 98 million cups of coffee are consumed across the UK every single day. This figure alone shows just how much we love it!

Why Weighing Your Coffee Is a Game Changer
Have you ever wondered why your morning coffee tastes absolutely perfect one day, only to be flat and disappointing the next? Even when you think you've done everything the same way, the results can be wildly different. I've been there, and the culprit is almost always a lack of consistency.
Moving past the familiar "scoop" is the single biggest leap forward you can take in your coffee journey. This isn't about getting overly technical or fussy. It's about taking control. When you embrace a simple digital scale, you eliminate the biggest guesswork in your morning ritual and finally unlock the secret to brewing a consistently brilliant cup.
The Trouble with Measuring by Volume
Using a tablespoon or a scoop to measure your coffee seems easy, but it’s a surprisingly flawed method. Coffee beans themselves are incredibly varied, and measuring them by volume hides a multitude of sins that directly impact the flavour in your cup.
- Roast Level: Dark roast beans are lighter and less dense than light roast beans because they've expanded more during roasting. A scoop of dark roast will weigh significantly less than the same scoop of a light roast.
- Grind Size: Think about it – fine grounds for espresso pack together tightly, while coarse grounds for a cafetière leave lots of empty space. A scoop of fine coffee contains much more actual coffee than a scoop of coarse coffee.
- Bean Origin: Just like different types of wood have different densities, so do coffee beans. A scoop of beans from Ethiopia won't weigh the same as a scoop from Colombia.
These variables mean you could be unknowingly using 20-30% more or less coffee than you intended. That’s a huge difference, and it’s why your brew can swing from strong and bitter to weak and sour without you changing anything else.
Precision is the Secret to Consistency
Switching to a scale and weighing your coffee in grams changes everything. A gram is always a gram. It doesn't matter if the coffee is dark-roasted, finely ground, or from the other side of the world. It’s a reliable, universal measure that ensures you use the exact same amount of coffee, every single time.
When you switch from scoops to a scale, you stop guessing and start brewing with intention. This simple shift is the foundation for confidently tweaking your recipes and truly understanding your coffee.
Getting this right is easier than you think. Tools like compact electric coffee grinders can help you achieve a uniform grind, but weighing your beans beforehand is what truly sets the stage for success.
Once you establish this solid, repeatable baseline, every other change you make—like adjusting your grind size or water temperature—can be measured properly. This is how you learn what truly makes a difference to the flavour in your cup. This is how you start brewing coffee that’s not just good by chance, but exceptional by design.
Mastering Ratios for Your Favourite Brewing Methods
A gleaming V60 dripper and a classic cafetière are both fantastic ways to make coffee, but they play by completely different rules. To get the best out of your equipment, you need to understand its unique personality. Each brewer has its own rhythm, and learning it is the secret to unlocking a truly exceptional cup, day after day.
This isn't just a list of recipes. Think of it as a deep dive into why certain methods work the way they do. We'll explore why full immersion brewers like the French press love a coarser grind and a heartier ratio, while a delicate pour-over needs a finer touch. Your brewer is your partner in this process—learning its language is the first step.
The infographic below gives you a brilliant at-a-glance guide to some common starting points.
As you can see, the answer to "how much coffee per cup?" really depends on the tools you're using.
The Full-Bodied French Press
The French press, a staple in so many UK kitchens, is all about creating a rich, full-bodied brew with a satisfying texture. The magic lies in immersion—the coffee grounds steep fully in the water for the entire brew time. This slow, gentle extraction is why a coarse grind is non-negotiable; anything finer and you’ll end up with a sludgy, bitter cup.
A fantastic starting point for any cafetière is a 1:15 ratio. For a typical 350ml press, that works out to about 23 grams of coffee.
My Tip: Treat the 1:15 ratio as your trusted baseline. If you brew a cup and find it a little too punchy for your liking, just dial it back to 1:16 next time (using a little less coffee for the same amount of water). It’s that simple tweak that puts you in the driver’s seat.
The Delicate Art of Pour-Over
Pour-over coffee, made with drippers like the iconic Hario V60 or a Kalita Wave, is a more hands-on affair that rewards you with incredible clarity and nuanced flavour. Unlike the all-in approach of immersion, here the water flows through the coffee. This makes your pouring technique and grind size absolutely critical for an even, balanced extraction.
For most pour-overs, a 1:16 ratio hits the sweet spot, yielding a beautifully balanced and clean cup. To brew a perfect 300ml mug, you’ll want to start with around 19 grams of medium-fine coffee. The real key is maintaining a slow, consistent pour to make sure all the grounds get the same amount of love.
The Chameleon: The AeroPress
Ah, the AeroPress. This brewer is a true chameleon, a master of disguise in the coffee world. It can produce anything from a short, intense, espresso-like shot to a clean and bright filter-style coffee. Its genius lies in combining immersion with pressure, giving you ultimate control.
For a classic filter-style brew that's clean and full of flavour, give this a go:
- Ratio: Start with a 1:14 ratio.
- Recipe: Use 15 grams of medium-fine coffee and fill the chamber with water up to the number 4 mark (roughly 220ml).
- Technique: Give it a quick stir for about 10 seconds, then press down firmly but gently for another 30 seconds.
The best thing about the AeroPress is how forgiving it is. It practically begs you to experiment. Tweak the grind, play with the brew time, try the inverted method—this is your chance to invent a recipe that’s 100% yours.
Recommended Ratios by Brew Method
To make things even easier, here’s a quick-reference table that brings it all together. These are my go-to starting points that I recommend to anyone looking to dial in their brew.
| Brewing Method | Recommended Ratio (Coffee:Water) | Suggested Grind Size | Key Brewing Tip |
|---|---|---|---|
| French Press | 1:15 | Coarse | Don't press the plunger all the way to the bottom; leave a small gap to avoid stirring up sediment. |
| Pour-Over | 1:16 | Medium-Fine | Pour in slow, concentric circles to ensure all coffee grounds are evenly saturated. |
| AeroPress | 1:14 (for filter style) | Medium-Fine | Experiment! This brewer is incredibly versatile. Try the "inverted" method for a fuller body. |
| Cold Brew | 1:8 | Coarse | Patience is key. Steep for at least 12-18 hours in the fridge for a smooth, low-acidity concentrate. |
Remember, these are just starting blocks. Your palate is the ultimate judge, so don't be afraid to adjust these ratios to create a cup that you truly love. Happy brewing
Finding Your Perfect Brew: Tweaking the Flavour
Think of the "golden ratio" as your launchpad, not your final destination. The truth is, the search for that truly perfect cup is a journey, and you're the one in the driver's seat. A good recipe isn't a rigid command; it's more like a friendly suggestion, an invitation to add your own flair.
This is where the real magic happens. It’s where you get to play, experiment, and dial in a brew that’s uniquely yours. Mastering this part of the process turns a simple morning routine into a moment of genuine, delicious discovery.
Listening to Your Coffee
Before you change a thing, you need to learn how to "read" your brew. What is it trying to tell you? Is the flavour a bit hollow and underwhelming? Or is it hitting you with an aggressive, bitter punch? These aren't mistakes; they’re clues that point the way forward.
Let’s break down what those clues mean.
- If your coffee tastes weak, thin, or watery: This is a textbook sign of under-extraction. Simply put, the water didn't have enough oomph to pull out all the good stuff from the grounds. Your first port of call should be adjusting the coffee-to-water ratio.
- If your coffee tastes overly bitter, harsh, or almost drying: This is a classic symptom of over-extraction. Here, the water hung around for too long and started extracting the unpleasant, bitter compounds. Again, the ratio is the first thing you should look at to fix it.
Once you get a feel for these two ends of the spectrum, you can start navigating the delicious territory in between.
Your palate is the only guide that matters. There’s no objectively right or wrong answer here, only what tastes absolutely fantastic to you. Trust your taste buds—they know what they’re doing and will lead you to the perfect balance of how much coffee per cup you truly enjoy.
Making Deliberate Changes
Right, let's turn that theory into action. Let's say you've just made a coffee using a common 1:16 ratio—for instance, 15g of coffee to 240g of water—and it’s not quite hitting the mark.
To Get a Stronger, Bolder Cup
If that brew felt a little weak, your aim is to increase the brew's concentration. The most efficient way to do this isn't necessarily to pile in more coffee grounds (which can get wasteful). Instead, try pulling back on the water just a little.
- Your Tweak: For the next round, stick with your 15g of coffee but use slightly less water—try 225g. This simple adjustment nudges your ratio to a stronger 1:15. It’s a small change, but it makes a big difference, concentrating the brew for a richer, more robust flavour without veering into bitterness.
To Get a Lighter, More Delicate Cup
On the other hand, if your last cup felt a bit too intense or bitter, you’ll want to do the opposite. You need to dial back the extraction to let the bean's subtler, more nuanced flavours come forward.
- Your Tweak: Once again, keep your coffee dose at 15g, but this time, add a touch more water—let's go with 255g. This moves you to a gentler 1:17 ratio. That little bit of extra dilution can smooth out any harsh edges, unveiling the lighter, more aromatic qualities you were missing.
The secret is to make these small, methodical adjustments one at a time. By only changing the amount of water, you can clearly taste the effect the ratio has. Once you've nailed the strength, then you can start playing with other factors like grind size or water temperature. This patient approach is how you build real confidence and finally master the art of brewing the perfect cup for you.

Your Common Coffee Brewing Questions Answered
As you dive deeper into the art of making coffee at home, you’ll naturally start asking more questions. It happens to all of us. These are the practical, nitty-gritty queries we hear all the time from coffee lovers on the very same journey as you—the quest to turn a decent cup into a truly exceptional one.
Let’s get into some of those common questions. Think of this as a conversation with a seasoned barista, giving you the clear, straightforward advice you need to fine-tune your technique and brew with confidence.
Does Water Temperature Really Matter That Much?
Oh, absolutely. It's one of the make-or-break details in brewing. The sweet spot for getting the most wonderful flavours out of your coffee is a surprisingly narrow window: 90–96°C (195–205°F). Getting this right changes everything.
If your water is too hot, it essentially scalds the grounds. This over-extracts all the harsh, bitter notes, leaving you with a nasty, astringent taste. On the flip side, water that’s too cool just doesn't have the energy to unlock the good stuff. You’ll end up with a brew that’s weak, sour, and frankly, a bit disappointing.
A Simple Pro Tip: You don't need fancy gear for this. Just boil your kettle, take it off the heat, and let it sit for 30–60 seconds before you pour. That little pause is usually all it takes to land the water temperature right in that perfect brewing zone.
How Much Coffee for One Cup in a Cafetière?
The cafetière (or French press) is a classic for a reason—it produces such a rich, full-bodied cup. For a standard 250ml mug, I’ve found that starting with 15–17 grams of coarse-ground coffee is the way to go. This gives you a lovely coffee-to-water ratio of around 1:15.
Let it steep for a full four minutes. Don't rush it! This gives those coarse grounds plenty of time to work their magic. From there, you can tweak it to your heart’s content. If it's a bit too bold for your liking, just dial back the coffee a gram or two next time until you find what makes you happy.
Can I Just Use Tablespoons Instead of a Scale?
Look, you can, but this is probably the number one reason home-brewed coffee is so inconsistent. It seems simple enough, but a tablespoon is a terrible way to measure coffee. Why? Because coffee beans have different densities.
A scoop of a dark, oily roast weighs much less than the exact same scoop of a dense, light roast. The grind size throws another spanner in the works; fine grounds pack together tightly, while coarse grounds are much fluffier. A "tablespoon" might hold 5 grams one day and 7 grams the next. That variation is precisely why a scale is a game-changer. Honestly, a simple digital kitchen scale is the best investment you can make to banish the guesswork and finally nail that perfect cup, every single time.
It's time to elevate your daily ritual from a guessing game to a moment of true greatness.
