Place a paper filter in the top of the Chemex with the three-sided part to the front (where the spout is).
Pour hot water into the Chemex and fill the bottom section. This will rinse the filter along with pre-heating the Chemex.
Remove the wet filter and tip out all the water, then put the filter back in the top.
Grind your coffee beans (if applicable) on a coarse setting.
Put coffee grounds in the filter – Depending on the size of your Chemex (3-8 cup), use a ratio of 1g coffee to 16ml water. For example, for a 3 cup you could use 20g of coffee and 320ml of water. This ratio should be changed to taste, which will require experimentation by you. You’re welcome!
Boil the kettle, and allow it to rest to ensure the temperature drops slightly below 100 degrees Celsius before using.
Initially pour in 2ml of water for every 1g of coffee, allowing the coffee grounds to bloom or expand.
Slowly pour the remainder of the water into the Chemex, ensuring all sections are covered. How you pour the water over the coffee is where the Chemex process becomes an artform!
As the last of the water drains through the filter, use a spoon to push any remaining coffee grounds down the sides of the filter.
Once all the water has drained through, the coffee is ready to drink. Remove the filter and pour!
Plunger
Preheat the plunger with hot water, tipping it out before brewing.
Grind your coffee beans (if applicable) on a coarse setting.
Put coffee grounds into the plunger, using a ratio of 1g coffee to 15-16ml of water. This ratio should be changed to taste and bean type.
Boil the kettle and immediately pour into the plunger.
Using a spoon lightly stir, ensuring all coffee is wet.
Once the brew time is complete, lightly press the plunger all the way down. If you have trouble pushing it down it could be due to the grind not being coarse enough.
Pour and drink!
Ensure all coffee is poured out after the brew time, because if you leave it in it will continue to brew and become bitter.
Siphon
Pre-boil some water.
Pour water in the bottom bowl (120ml per cup) and light the alcohol burner or whatever heating method you are using.
Place the filter into the upper bowl with the stem pointing down the tube. Don’t forget to attach the hook on the end of the stem!
Put medium ground coffee into the upper bowl (10g per cup).
Take care to ensure heat is removed when the lower bowl is almost empty and allow the coffee to drip into the bottom bowl.
Once it is empty of water, carefully remove the upper bowl.
Enjoy. Repeat.
Stovetop
Fill the bottom part of the Stovetop with water. Make sure you don’t fill it past the steam release valve.
Reattach the top (filter) onto the bottom section and fill it with coffee grounds (ground fine – suitable for espresso style coffee) – do not tamp the coffee!
Screw on the top tightly (ensure the filter plate is in place properly first).
