What Is a Chemex Coffee Maker?
How the Chemex pour over coffee maker creates a distinctive brew
The Chemex pour over coffee maker combines a simple brewing method with an instantly recognisable silhouette. Its cone shaped upper section holds the filter and grounds, while the brewed drink collects below. This manual approach gives you control over preparation and is particularly suited to anyone who enjoys making pour over coffee and exploring delicate aromatic profiles.
The brewer is made from porous borosilicate glass, selected to provide a clean brewing surface that does not absorb odours or chemical residues. Its functional construction and timeless design have helped make Chemex an icon of manual preparation.
Chemex filters and their role in extraction
Dedicated Chemex filters are an essential part of the system. These paper filters retain grounds and oils during extraction, contributing to the clean and clear cup associated with this brewer. Choosing the appropriate coffee filters for your model is therefore important for consistent preparation.
Before adding the grounds, rinse the filter with a small amount of water. This helps prepare the filter and preheat the glass coffeemaker before brewing begins.
How to Choose the Best Chemex Coffee Maker
3 Cup Chemex Coffee Maker, 6 Cup Chemex Coffee Maker and larger sizes
Choosing between sizes depends primarily on how much you usually prepare:
- A 3 cup Chemex coffee maker is a compact choice for smaller quantities, ideal for one or two cups.
- A 6 cup Chemex coffee maker offers greater capacity for everyday use or sharing with a few people.
- The Chemex coffee maker 10 cup provides the largest volume, suitable for households or when preparing multiple servings at once.
Among the key features to compare are actual capacity, dimensions and handling. Remember that the manufacturer's cup measurements do not necessarily correspond to a standard UK mug, so checking the stated volume can help you choose the most appropriate model.
Classic, glass handle and other Chemex designs
Chemex models also differ in appearance and handling. The Classic Series features the characteristic wooden collar, creating the distinctive look associated with the brand. Models with a glass handle provide an alternative for those who prefer an integrated grip and an all-glass aesthetic.
The best Chemex coffee maker for you will therefore depend on both capacity and design preference. Whichever version you choose, make sure you pair it with filters designed for its particular size and shape.
How to Use a Chemex Coffee Maker
Choosing coffee, grind size and ratio for your Chemex
Preparing excellent coffee at home begins with freshly ground beans and a recipe you can reproduce. A medium-coarse grind is a useful starting point, although adjustments may be needed depending on the beans, dose, and desired extraction.
- 3 cup Chemex: use around 15–20 g of coffee for 250–300 ml of water, a slightly finer medium-coarse grind helps maintain clarity in such a small brew and avoid under-extraction
- 6 cup Chemex: aim for 30–40 g of coffee for 500–700 ml of water, a classic medium-coarse grind works best to balance sweetness, body and clarity
- 10 cup Chemex: use 50–60 g of coffee for 900–1200 ml of water, slightly coarser grinding helps maintain a steady flow rate and prevents over-extraction during longer pours
Using a scale makes it easier to control the ratio between grounds and water. Once you have established a starting recipe, small changes to grind size or ratio can help you refine sweetness, body and aromatic clarity.
Mastering the Chemex pour technique
After rinsing the filter, add the grounds and pour a small amount of hot water over the grounds, ensuring they are evenly saturated. Allow this initial bloom to develop before continuing with slow, controlled pours.
A gooseneck kettle can provide greater control over flow and direction. With practice, adjusting pouring speed and timing allows you to refine the extraction and develop a repeatable recipe with your coffee maker.
