Brew Guides

No gatekeeping.
No jargon.

Just how to make a great cup with what you've got. Every method below follows the same format: what you need, the numbers that matter, a simple step-by-step, and one tip that'll actually make a difference.

If something tastes off, the answer is almost always grind size or water temperature. We'll tell you which one to adjust in each guide.

The one that matters most. If you've got a Sage, a Breville, or any machine with a portafilter, this is your daily ritual. Here's how to get it right without overthinking it.

MachineAny espresso machine with a portafilter GrinderBuilt-in or standalone burr grinder
Dose18g of coffee Yield36g of liquid espresso
Time25–30 seconds Water Temp92–96°C
1Grind 18g of coffee into your portafilter. You want it fine — like table salt, not sand, not powder.
2Distribute the grounds evenly and tamp firmly with a flat, level press. You're not trying to compact it into a diamond. Firm and flat will do.
3Lock the portafilter in, place your cup underneath, and start the shot.
4You're aiming for roughly 36g of liquid espresso in 25–30 seconds. If it's gushing out too fast, go finer. If it's barely dripping, go coarser.
5Drink it. If it tastes sour, grind finer next time. If it tastes bitter, go a touch coarser. That's the whole game.
GRNDUP Tip

If you're using a Sage Barista Express, start at grind setting 8 and adjust from there. Every bag of coffee will behave slightly differently, so don't be afraid to move it around.

Everyone owns one. Most people use it wrong. This is how you get a properly good cup out of that glass jug gathering dust in your cupboard.

EquipmentFrench press (any size) GrinderBurr grinder or pre-ground (coarse)
Ratio15g coffee per 250ml water GrindCoarse — like rough sea salt
Water TempJust off the boil (~95°C) Brew Time4 minutes
1Boil your kettle, then let it sit for about 30 seconds. You want it hot, not volcanic.
2Add your coarsely ground coffee to the press. For a standard mug, that's roughly 15g (about two heaped tablespoons).
3Pour the water in steadily, making sure all the grounds get wet. Give it one gentle stir.
4Pop the lid on (plunger up) and leave it alone for 4 minutes. Set a timer. Don't guess.
5Press the plunger down slowly and steadily. If it feels like you're wrestling it, your grind is too fine.
6Pour immediately. Don't leave it sitting in the press or it'll keep extracting and turn bitter.
GRNDUP Tip

The single biggest upgrade you can make here is grinding fresh rather than using pre-ground. Even a cheap hand grinder will make a noticeable difference.

Portable, forgiving, and weirdly fun. The AeroPress is a favourite for a reason — it's nearly impossible to make a bad cup with one.

EquipmentAeroPress + paper or metal filter GrinderBurr grinder
Dose15g coffee Water200ml at ~85°C
GrindMedium-fine — between espresso and filter Brew Time2 minutes total
1Pop the plunger into the chamber and flip the whole thing upside down so it's standing on the plunger. This stops coffee from dripping through before you're ready.
2Add 15g of medium-fine ground coffee.
3Pour in 200ml of water at around 85°C. Give it a quick stir — five seconds, nothing fancy.
4Place a rinsed paper filter in the cap and screw it on.
5At the 1 minute 30 mark, carefully flip the whole thing onto your mug and press down gently over about 20–30 seconds.
6Stop pressing when you hear the hiss. That's air — you're done.
GRNDUP Tip

The AeroPress is incredibly forgiving. If your coffee tastes thin, add more grounds or let it steep a bit longer. If it's too strong, just add a splash of hot water after pressing. No rules here.

This is the one that looks the most like a ritual. It takes a bit more attention than the others, but the reward is a clean, bright cup that lets the coffee do the talking.

EquipmentV60 dripper + paper filters + server or mug GrinderBurr grinder
Dose15g coffee Water250ml at ~93°C
GrindMedium — like granulated sugar Brew Time2:30–3:30 total
1Place the paper filter in your V60 and rinse it thoroughly with hot water. This removes any papery taste and pre-heats the dripper. Discard the rinse water.
2Add 15g of medium-ground coffee and give the dripper a gentle shake to level the bed.
3Start your timer. Pour 30ml of water in a slow spiral to wet all the grounds, then wait 30 seconds. This is the bloom — you'll see the coffee puff up and release gas. That's freshness.
4From 0:30, pour the remaining water in slow, steady circles. Avoid the edges of the filter. You're aiming to finish pouring by about 1:45.
5Let it drip through completely. Your total brew time should land between 2:30 and 3:30.
6Swirl the server gently and pour.
GRNDUP Tip

If your brew finishes much faster than 2:30, your grind is too coarse. If it's dragging past 3:30, go coarser. The grind is your main control here.

The stovetop classic. It won't make true espresso, but it'll make something strong, rich, and satisfying — and it costs about twenty quid.

EquipmentMoka pot (any size) GrinderBurr grinder or pre-ground (fine)
DoseFill the basket (don't tamp) WaterFill to below the valve with hot water
GrindFine — finer than filter, coarser than espresso HeatMedium-low stovetop
1Fill the bottom chamber with hot water from the kettle, up to just below the safety valve. Starting with hot water means the coffee spends less time on heat, which means less bitterness.
2Fill the filter basket with finely ground coffee. Level it off but don't tamp it down. Just a gentle level.
3Assemble the pot (careful — the bottom is hot) and place it on a medium-low hob.
4Leave the lid open so you can watch. Coffee will start bubbling up into the top chamber after a minute or two.
5As soon as you see a steady, honey-coloured stream, you're in the sweet spot. When it starts to sputter and lighten in colour, take it off the heat immediately.
6Run the base under cold water to stop extraction. Pour and enjoy.
GRNDUP Tip

The number one mistake with a Moka pot is too much heat. Keep it at medium-low. High heat scorches the coffee and gives you that burnt, metallic taste everyone blames on the pot itself.

Low effort, high reward. Cold brew is smooth, naturally sweet, and basically makes itself overnight. It's also a great way to use up beans that have been open a bit longer than ideal.

EquipmentLarge jar, jug, or French press GrinderBurr grinder or pre-ground (very coarse)
Ratio70g coffee to 500ml cold water GrindVery coarse — like raw sugar or breadcrumbs
Brew Time12–24 hours in the fridge ServesMakes a concentrate (dilute to taste)
1Grind 70g of coffee very coarsely. This is coarser than you'd use for anything else — think chunky breadcrumbs.
2Combine the grounds with 500ml of cold or room temperature water in a jar or jug. Stir gently to make sure all the grounds are wet.
3Cover it and stick it in the fridge. Then forget about it for at least 12 hours. 18–24 is even better.
4Strain through a fine sieve, cheesecloth, or paper filter. You want a clean liquid with no grit.
5What you've got is a concentrate. Dilute it roughly 1:1 with cold water or milk, or adjust to your taste. Pour over ice and you're sorted.
GRNDUP Tip

Cold brew concentrate keeps in the fridge for up to two weeks. Make a big batch on Sunday and you've got effortless iced coffee all week.

Which Coffee, Which Method?

Not sure which GRNDUP batch to use with which brew method? Here's a rough guide.

Espresso

Our blends (Batch No. 01–04) are roasted with espresso in mind. They're designed to deliver balanced, sweet shots with body. If you're pulling shots daily, start here.

Cafetière & Cold Brew

The medium and darker roast blends work brilliantly here. Their heavier body stands up well to the longer steep times. Try Batch No. 01 or No. 02 for a reliable, rich cup.

AeroPress & Pour Over

This is where the single origins (Batch No. 05 onwards) really shine. Lighter roasts and more delicate flavours come through beautifully with these methods. If you want to taste what makes a Colombian different from an Ethiopian, filter brewing is the way.

Moka Pot

Treat this like espresso's slightly louder cousin. The blends work well, but a punchy single origin can be brilliant here too. Experiment.
