Welcome to the Chemex

The Chemex. An elegant, timeless brew method perfect for the entertainer.

This is the perfect piece of kit if you are regularly making coffees for friends and family, (and maybe even want to show off a little bit!).

With a super thick filter, the Chemex filter coffee maker stands out as it provides arguably the cleanest cup out there. If you are a frequent user of a cafetiere, this may just change your world.


Easy to do, but takes a few minutes of concentration without distractions.

*If you don’t have a coffee grinder, make sure the coffee you are using is ground for filter, a medium-fine grind size.


30g medium-coarsely ground coffee per 500ml water.



This is key to getting your brew tasting consistently good and means you can replicate good results.

If you’re brewing for 2 people, we recommend starting with 30g of coffee, and 500ml water. Aim for a medium-coarse grind.

You may enjoy your coffee stronger or weaker, so as a general rule we’d say anywhere between 60-70g per litre of coffee.

It’s your brew, and experimenting to find the perfect ratio for you is absolutely encouraged.


Pop the filter into your Chemex and rinse with hot water. This means you only taste the good stuff in your brew, and not the taint of the paper – same as when you’re brewing with V60 or any other pour-over method which uses a filter.

This is also a good time to preheat your vessel too which will keep your coffee hotter for longer. Swirl the hot water around the Chemex.


Tip away any hot water in your Chemex and add your ground coffee into the filter paper in the coffee maker.

Start the first pour. The aim here is to saturate the grounds, this should require only 80-100ml of the total water. Swirl it around a little so that all of the coffee grounds are fully saturated.

Watch as the coffee expands and de-gasses. This process is called the bloom.

Wait 20-30 seconds here before moving on to the main pour.


Try to pour consistently, at a steady rate, and in a circular motion. This keeps the coffee grounds fully immersed without weighing the coffee down with all the water at once.

Pause every 100ml for a few seconds to keep the water level only a few mm above the grounds. Nice and slow.

The total brew time (including bloom) should be around 5 minutes.
