Chemex is a company based in Massachusetts (where we are!) that specializes in producing pour-over style coffee makers and filters. The Chemex coffee maker is a manual, pour-over style brewer that uses a particular type of filter thicker than those used in traditional drip coffee makers. This results in a cleaner and purer cup of coffee. Most days I use a v60 for single cup or two cups, and my larger Chemex when I have 3 of 4 guests.
The Chemex coffee maker is made from borosilicate glass, a heat-resistant and non-porous material. This means that the coffee does not come into contact with any materials that could affect the taste or aroma. The Chemex company is located in Chicopee, Massachusetts. Dr. Peter Schlumbohm invented the Chemex coffee maker in 1941. It has since become popular among coffee enthusiasts for its simplicity and ability to produce a clean and flavorful cup of coffee.
The filters are about 20% thicker than ordinary filters – you can feel the quality when you use one. It makes a big difference in the quality of the coffee you can extract, which is why the Chemex system is so popular among lovers of small-lot specialty coffees. We recommend unbleached filters.
Another option we love is the Chemex Coffeemaker, paired with the Able KONE metal filter. This is sustainable, aesthetically pleasing, and makes fantastic coffee. I do think paper absorbs some negative taste particles in coffee.
To make pour over coffee with a Chemex coffee maker, you will need the following:
- Whole bean coffee, freshly ground
- Hot water, just off the boil
- Chemex coffee maker
- Chemex filters
- A scale
- A kettle or pouring device
- A timer (optional)
Steps:
- Fold the Chemex filter in half, then in half again, and place it in the Chemex with the three-layered side towards the pour spout.
- Rinse the filter with hot water to remove any paper taste and preheat the Chemex.
- Place the Chemex on a scale and tare it to zero.
- Add the ground coffee to the filter, use the recommended coffee to water ratio (usually 1:15)
- Start a timer and pour a small amount of hot water over the coffee to saturate it (around 60g for a 8 cup Chemex)
- Wait for the coffee to bloom, around 30 seconds
- Slowly pour the remaining hot water over the coffee in circular motions, aiming for an even extraction.
- Once the timer reaches the desired brew time (usually around 4 minutes for a full Chemex) remove the filter and coffee grounds and serve.
Note: The above is a basic recipe, you can experiment with different coffee to water ratio, bloom time and brew time to find your preferred taste.
