Chemex uses a proprietary filter that is 20-30% thicker than standard paper filters. This traps more oils and micro-particles, resulting in a cleaner, more transparent cup than V60. Chemex also allows larger batch brewing of 3-6 cups at a time.
Use a medium-coarse grind for Chemex, slightly larger than sea salt. Because the thick filter already slows the water flow, you need a coarser grind than V60. The total brew time should be around 4 to 4:30 minutes.
A full 6-cup Chemex brew uses approximately 42-50 grams of coffee. With 1 KG, you can make 20-24 full batches. For single cups at 15-17 grams, that is roughly 60 cups.
1 kilogram of Chemex coffee is a medium-coarse specialty grind optimised for the Chemex brewer's distinctive thick paper filter. This grind size produces a crystal-clear, clean and pure coffee profile, and the bulk format makes it an economical choice for dedicated Chemex users.
Chemex brewing typically requires 30-45 grams of coffee per batch (500-750 ml). A 1 kg bag therefore delivers 22-33 brews — roughly 3-4 weeks of daily Chemex sessions.
The Chemex grind is one step coarser than V60. The reason is the Chemex's bonded paper filter, which is 20-30 % thicker than standard pour-over filters. That extra thickness slows water flow, so a coarser grind is needed to compensate. Otherwise the brew time stretches too long and you end up with an over-extracted, bitter cup.
Our 1 kg Chemex bags shine with aromatically complex single-origin coffees. Chemex's ultra-clean profile strips away virtually all oils, leaving only dissolved flavour compounds. On that transparent canvas, Ethiopian floral notes and Kenyan red-fruit acidity appear with stunning clarity.
The Chemex filter is thick. Go one notch coarser than your V60 setting, or brew time will stretch and the cup will turn bitter.
Chemex's clean profile pairs best with aromatically rich coffees. Ethiopian and Kenyan lots are ideal companions.
The Chemex filter carries more papery taste than thinner filters. Rinse thoroughly with hot water before you brew.
“Committing to a 1 kg Chemex bag is serious, but with the right origin the reward is immense. A single-origin Ethiopian natural — every brew feels like walking through a jasmine garden.”— Fuga Coffee Brewing Team
