What grind size does CHEMEX recommend for the CM-6A Six Cup Classic?
CHEMEX's instructions recommend grinding whole-bean coffee to a medium-coarse consistency for brewing in the CM-6A Six Cup Classic. This is the manufacturer's starting guidance; you can adjust your grind to suit your brewing results.
How much coffee does CHEMEX suggest using per cup?
As a starting point, CHEMEX says to put one rounded tablespoon of ground coffee into the filter for every 5-ounce cup. For a stronger brew, its instructions say you may use more coffee, while keeping the CM-6A's desired batch size in mind.
How should the Bonded filter be positioned in the CM-6A?
Open a CHEMEX Bonded Coffee Filter into a cone and place it in the top of the brewer so one side has three layers. CHEMEX instructs that this thicker, three-layer portion should cover the CM-6A's pouring spout.
How does CHEMEX recommend blooming and pouring?
After bringing the water to a boil, remove it from the heat and let vigorous boiling stop. Wet the grounds with a small circular pour and wait about 30 seconds for blooming. Then pour slowly, keeping the water level at least a quarter inch below the top of the brewer.
Are the filters used with the CM-6A compostable?
CHEMEX's CM-6A brewing instructions say to remove the spent filter and grounds after brewing and state that its filters are biodegradable and compostable. Disposal should follow the requirements of your local composting service or program.
Does the CM-6A's wooden collar change how the coffeemaker works?
CHEMEX says the difference between coffeemakers with wooden collars and those with glass handles is aesthetic and does not change functionality. The CM-6A is the wood-collar version and includes a polished wood collar with a leather tie.
Does the CM-6A's glass add flavor or chemicals to coffee?
CHEMEX describes its coffeemakers as made from high-quality borosilicate glass, the same type used for labware, and says the glass will not impart chemicals or flavors into the coffee. This description applies to the Six Cup Classic product page.
How is the Six Cup Classic prepared before it is shipped?
The manufacturer says each CHEMEX coffeemaker is inspected, polished, and hand-tied by a team member before being boxed for shipping. For the CM-6A, that preparation accompanies the wood collar and leather-tie design shown on the product page.
