A Brighter, Cleaner Cup

During your coffee tasting journey you come across different ways of brewing the good stuff, yet for all the brewing devices available today, the Chemex coffee maker continues to stand out as the brightest innovation.

Invented by Peter Schlumbohm in 1941, he sought to create a device that could brew perfect coffee.

A lot of thought and consideration went into the Chemex’s functionality; from the coffee chemistry, to its glass design and the thick paper filters – all in hopes of removing unwanted bitterness while still retaining full flavor.

The Chemex is considered “one of the best-designed products of modern times” and is featured as part of the MOMA‘s permanent collection. ( Museum Of Modern Art )

” Like all good things, full flavor takes time — and your own special touch. The CHEMEX®Coffeemaker delivers only the elements essential to rich coffee flavor, so that your personal taste and approach shine through.”

What makes Chemex unique ?

Aside from it’s stunning design – what makes this coffee maker unique is its singular solid piece of borosilicate glass (pyrex) with integrated cone, spout and decanter in one.

The unique shape of the Chemex aids during the brewing process by providing aeration and an even temperature retention for rich coffee extraction, unlike anything else before it.

Modeled after scientific lab equipment, it features a simple wooden collar , that’s attached and held on by a leather strap. This makes it safe and convenient to hold as necessary during or after the brewing process.

The unique design of the Chemex brewer, in conjunction with the extra thick filtration paper, all need special care and attention during the brewing process to deliver a superior cup of coffee.

Chemex How To

What You’ll Need:

✔️Chemex: The brewer of choice is the 6-Cup Chemex – we find it’s the perfect size for brewing multiple cups of coffee.

✔️Chemex Bonded Filters :  A definite must have – part of the success of the Chemex is these bonded paper filters. They efficiently remove the bitter flavors and stray components (oils) during your brew, due to their thickness, and allows for a brighter and cleaner cup of coffee.

✔️Gooseneck Kettle: Precision is what brewing with a Chemex is all about. A good gooseneck kettle, will help you have better control over your pour.

✔️Scale: Consistency is key! -Aside from grinding your coffee correctly, weighing your coffee with a gram Scale, will provide you with a more balanced brew every time.

*When brewing with a Chemex or any pour over/immersion method, a scale will help you determine the amount of coffee and water you’re going to need for each particular brew (recipe/ratios).

Using exact measurements during this brew guide will help you accomplish an exceptional cup of Chemex coffee.
