The Chemex
Chemex is a filter-coffee brewing device consisting of an hourglass-shaped glass flask and a paper filter. The brewing method that employs this coffee maker is referred to by the same name.
Brewing coffee with a Chemex device is a simple process.
Here’s what you will need:
- Chemex device
- Special filters
- Coffee beans
- Coffee grinder
- Kettle
- Precision coffee scale
- Timer
- Mug
Follow these step-by-step instructions:
- Boil water in the kettle and let it cool for 1 to 2 minutes until it reaches a temperature of 195–205 °F (90–96 °C).
- Place the filter in the Chemex. Make sure that the side with three layers faces the spout.
- Moisten the filter with hot water to remove any paper taste and slightly warm the sides of the Chemex.
- Drain any excess water from the flask.
- Grind the coffee beans to a medium consistency.
- Use a scale to measure 1 gramme of coffee per 15 grammes of water. For instance, use 20 grammes of coffee for a 300-ml cup.
- Add the coffee grounds to the Chemex.
- Begin the timer and pour a small amount of hot water (2 times the coffee’s weight) over the ground coffee, ensuring that it is evenly moistened.
- Let it sit for roughly 30 seconds.
- Slowly pour the remainder of the hot water over the coffee grounds in circular motions to ensure even extraction.
- Wait until the coffee ceases dripping through the filter (about 3–4 minutes).
- Remove and discard the filter.
If the coffee seems too weak, you can use more ground coffee beans or a finer grind. If the coffee is too strong, decrease the quantity of ground coffee beans and use coarser grindings.
