- Heat Source: Hot water is essential for extraction. The temperature of your water can significantly impact how well the coffee flavors are released.
- Filters: Chemex filters are thicker than standard filters. This impacts the flow rate and how much coffee oils are allowed into the brew.
Why Grind Size Matters
Grind size plays a pivotal role in the extraction process. The size of your coffee grounds affects:
- Extraction Rate: Finer grinds extract flavors more quickly, while coarser grinds take longer.
- Flavor Profile: The right grind size can help preserve or enhance certain taste profiles, such as acidity, sweetness, or bitterness.
- Brew Time: The Chemex requires a specific grind size to balance the brew time, ensuring you get the most from your beans without over-extraction.
What Grind Coffee for Chemex?
The ideal grind size for Chemex brewing is medium-coarse. A medium-coarse grind resembles sea salt in texture and ensures optimal water flow while allowing sufficient extraction time.
Characteristics of Medium-Coarse Grind
- Texture: A medium-coarse grind has particles that are not too fine to clog the thick filter, ensuring smooth water flow. It also isn’t too coarse, which could lead to under-extraction.
- Extraction: This grind size strikes a balance between flavor extraction and brewing time, resulting in a clean and flavorful cup of coffee.
Why Not Finer or Coarser Grinds?
-
Fine Grind: Using too fine of a grind in a Chemex could lead to over-extraction. Over-extracted coffee can taste bitter and unpleasant. Fine grinds can also clog the filter, slowing down the brewing process and leaving you with a muddy coffee.
-
Coarse Grind: Conversely, a very coarse grind will result in under-extraction, leading to a weak and watery cup of coffee. The flavors may become dull and fail to express the richness of the chosen beans.
Benefits of Using the Right Grind Size
Using the right grind size can vastly improve your coffee experience. Here are some key benefits of sticking to a medium-coarse grind for your Chemex:
1. Balanced Flavor Profile
A medium-coarse grind allows for a balanced extraction of flavors, capturing the coffee’s inherent sweetness and acidity without overwhelming bitterness.
2. Clean Finish

2. Water Temperature
Use water heated to between 195°F to 205°F (90°C to 96°C). This temperature range promotes optimal extraction without burning the coffee.
3. Bloom Your Coffee
Before fully saturating your coffee grounds, pour a small amount of hot water (about double the weight of the coffee) over the grounds and allow them to bloom for 30-45 seconds. This releases carbon dioxide and enhances flavors.
4. Pouring Technique
When pouring your hot water, start from the center and spiral outwards. This technique ensures even saturation of all grounds, allowing for uniform extraction.
5. Patience is Key
Allow your coffee to drain completely before removing the filter. Rushing can leave residual water and lead to over-extraction, negatively impacting flavor.
Maintaining Your Chemex
Proper maintenance of your Chemex is essential for long-term use. Follow these guidelines to keep your device in pristine condition:
1. Cleaning After Each Use
After brewing, rinse the filter and rinse both the Chemex and filter holder with hot water. This helps prevent coffee oils from building up, which can affect future brews.
2. Deeper Cleaning
Periodically, it is advisable to clean your Chemex with a mixture of water and vinegar to break down any residue. Allow it to soak for 30 minutes and then rinse thoroughly with warm water.
