- Uneven Creases: Failing to create a crisp crease during folding can result in a poorly structured filter that affects water flow.
Brewing with Your Chemex
Now that your filter is perfectly folded and fitted into the Chemex, it’s time to brew that delicious cup of coffee.
Measuring Your Coffee
A general rule of thumb is to use a coffee-to-water ratio of 1:15. For instance, if you’re brewing 300 ml of coffee, use 20 grams of coffee beans. Adjust the ratio based on your taste preference.
Grinding Your Coffee
For Chemex brewing, a medium-coarse grind is ideal. It should resemble the texture of sea salt. Grinding too fine can lead to over-extraction and bitterness, while too coarse can result in under-extraction and sourness.
Pouring Water
Before pouring hot water over your coffee grounds, it’s vital to pre-wet the filter. Pour a small amount of hot water into the filter to rinse off any papery taste and to preheat the Chemex. Discard the rinse water and begin adding your ground coffee.
Blooming the Coffee
Pour a small amount of hot water over the grounds, just enough to saturate them, and let it sit for about 30 seconds. This process, known as blooming, allows carbon dioxide to escape, enhancing the flavor of your brew.
Complete the Brew
After blooming, slowly pour in the remaining water in a circular motion, allowing it to flow evenly over the coffee grounds. Once you’ve added all the water, let the coffee drip fully into the Chemex.
Cleaning Your Chemex After Use
To maintain the longevity of your Chemex and its filters, cleaning is essential. Here are some tips:
Rinsing the Filter
After brewing, while the grounds are still moist, remove the filter from the Chemex and discard it. Rinse the Chemex with warm water to prevent residue buildup.
Deep Cleaning
Periodically, it’s advisable to deep clean your Chemex with a mixture of baking soda and vinegar. Allow it to soak for about 30 minutes before rinsing thoroughly.
