Invented in 1941 by chemist Peter Schlumbohm, this hourglass-shaped glass coffee maker has been part of MoMA's permanent collection since 1944 — and has barely changed since. But the Chemex isn't beloved only for its looks. The coffee it produces is genuinely, distinctively excellent. This review explains why. > **See the summary at the top of the page for key points.** ## What Is the Chemex? ![Chemex coffee maker review and how to use](https://coffee-guide.jp/images/articles/gear/chemex-review-how-to-use-section-1.webp) The Chemex is a pour-over coffee brewer and server in one piece. You pour hot water through a paper filter seated at the top of the glass vessel, and brewed coffee drips directly into the lower chamber — ready to pour and serve immediately. The glass is borosilicate, highly heat-resistant and non-porous (no flavor absorption). The classic design features a polished wood collar tied with a rawhide cord. No moving parts, no electricity, no mechanism to break. ### Why Chemex Coffee Tastes So Clear The defining characteristic of Chemex coffee is its **clarity**. The brew is unusually light-bodied, bright, and clean — low in the oily texture that characterizes French press or even many pour-overs. This comes directly from the **Chemex bonded filters**, which are 20–30% thicker than standard paper filters. The extra thickness traps: - **Coffee oils** (which add body but also bitterness) - **Fine coffee particles** (which cause sediment and muddy flavor) The result is a cup with exceptional transparency of flavor — especially suited to light and medium roasts where you want to taste the origin characteristics of the bean. If you're brewing a washed Ethiopian or a floral Kenyan, Chemex is the format that shows it best. --- ## Chemex Models ### Chemex 3-Cup (CM-1) > **CHEMEX Coffee Maker 3-Cup CM-1 Official Import** / 価格: ¥9,800 / 評価: 4.3 / 特徴: 3-cup capacity / Dripper + server in one / Borosilicate glass / Rawhide collar / Official import → [Amazonで商品を見る](https://www.amazon.co.jp/dp/B004BEQFVY?tag=ps0036fr-22 ) ※アフィリエイトリンク The smallest Chemex, suitable for 1–2 cups at a time. Compact enough for a studio apartment counter, and lightweight enough to handle easily. The limitation is volume — if you regularly want more than two cups, you'll be making multiple batches. ### Chemex 6-Cup (CM-6A) — Most Recommended > **CHEMEX Coffee Maker 6-Cup CM-6A Official Import** / 価格: ¥12,800 / 評価: 4.5 / 特徴: 6-cup capacity / Dripper + server in one / Borosilicate glass / Wood handle / Official import → [Amazonで商品を見る](https://www.amazon.co.jp/dp/B00XIZ1I6O?tag=ps0036fr-22 ) ※アフィリエイトリンク The **6-cup is the most popular and most recommended Chemex**. It handles solo brews and small gatherings equally well, and the wooden handle collar makes it the most iconic-looking of the three sizes. This is the model to buy unless you have a specific reason for a different size. ### Chemex 8-Cup (CM-8A) > **CHEMEX CM-8A Coffee Maker 8-Cup** / 価格: ¥14,500 / 評価: 4.4 / 特徴: 8-cup capacity / Dripper + server in one / Borosilicate glass / Large capacity / Wood handle → [Amazonで商品を見る](https://www.amazon.co.jp/dp/B000I1WP7W?tag=ps0036fr-22 ) ※アフィリエイトリンク For households of four or more, or anyone who hosts coffee sessions regularly. The 8-cup requires more grounds and water (and more arm endurance during the pour), but produces enough for a full table without needing a second batch. - **3-cup**: Solo use only — small apartment, minimal counter space - **6-cup**: Best for most people — versatile from solo to small gatherings - **8-cup**: Large families or hosting-focused buyers - **Default recommendation**: 6-cup (CM-6A) --- ## Chemex Filters: What You Need to Know The Chemex **requires its own bonded filters** — standard V60 or Kalita filters will not produce the same result and don't fit properly. Chemex filters are square, folded into a cone shape before use. **Filter types available:** - **White (bleached)**: The standard choice — clean, neutral paper taste - **Natural (unbleached)**: Slightly more eco-friendly, mild paper note Always rinse the filter with hot water before adding coffee. This removes the paper taste and preheats the glass vessel. --- ## How to Brew with a Chemex ### What You Need - Chemex (your chosen size) - Chemex bonded filters - Coffee beans, medium-coarse grind - Gooseneck kettle - Scale ### Basic Recipe (6-cup / Serves 2–3) | Parameter | Target | |-----------|--------| | Coffee | 40g | | Water | 600ml (1:15 ratio) | | Water temp | 92–95°C (198–203°F) | | Bloom | 45 seconds | | Total brew time | 4:00–5:00 | ### Step-by-Step **1. Fold and place the filter** Fold the square filter in half once, then again into a quarter cone. Place it in the top of the Chemex with three layers facing the spout side — this is important for even drainage. **2. Rinse the filter** Pour hot water through the filter to rinse it and preheat the glass. Discard the rinse water (pour it out through the spout). **3. Add coffee** Add your medium-coarse grounds. For a 6-cup batch, use 40g. Scale proportionally: 13–15g per 200ml cup you want to brew. **4. Bloom** Pour just enough water to saturate all the grounds (roughly 2–3× the coffee weight in ml). Wait 45 seconds. Chemex blooms are slightly longer than other pour-overs because the thick filter extends total brew time. **5. Main pour** Pour in 4–5 additions, slowly, using concentric circles from center outward. Let each addition drain partially before the next. Total pour time will be 4–5 minutes. The thick filter slows extraction — don't rush it. **6. Remove and serve** Lift out the filter (and coffee grounds together — it's tidy). Pour directly from the Chemex. No separate server needed. --- ## Cleaning the Chemex Cleaning is straightforward: rinse with warm water after use. The wood collar ties off for removal before washing. A bottle brush reaches the narrow neck. Chemex also sells a dedicated cleaning brush sized for their vessels. Avoid harsh detergents — borosilicate glass doesn't absorb flavors, but residue buildup inside the neck can affect taste over time. A weekly rinse with hot water and a mild soap is sufficient. --- ## Pros and Cons **Pros** - Produces the clearest, cleanest pour-over cup of any common dripper format - Combined dripper-and-server reduces equipment and counter space - MoMA-collection design that genuinely improves kitchen aesthetics - 80+ years of proven design — nothing to break or maintain - Excellent showcase for light-roast and single-origin specialty coffees **Cons** - Requires proprietary bonded filters — standard filters can --- ## Verdict The **Chemex** is the best argument that coffee equipment can be both beautiful and functionally excellent. Its thick-bonded filters create a cup style genuinely unlike anything else — clear, bright, and almost tea-like in its delicacy — that shows the best qualities of quality light and medium roasts. If you're buying your first Chemex, get the **6-cup CM-6A**. It's versatile, iconic-looking, and gives you enough capacity to serve guests without needing a second brew. The Chemex isn't the right choice for dark-roast lovers or anyone who prefers a heavy, oily body in their cup. But for anyone who drinks specialty coffee and wants to experience what a truly clean pour-over tastes like, the Chemex is the definitive choice. > 💡 **TIP** > > Grind slightly coarser than you would for a V60 — medium-coarse rather than medium. The Chemex filter is thick enough to slow flow significantly; if you grind too fine, the brew will stall. If your total brew time consistently exceeds 5 minutes, try a coarser grind. ## Related Articles - [Dripper Comparison: V60 vs Kalita Wave vs Chemex vs ORIGAMI [2026]](https://coffee-guide.jp/gear/dripper-comparison-v60-kalita-chemex-origami) - [Kalita Wave Dripper Review — Why It's the Best Beginner Pour-Over Dripper](https://coffee-guide.jp/gear/kalita-wave-dripper-review) - [ORIGAMI Dripper Review — The Multi-Filter Dripper from Japan's Pottery Capital](https://coffee-guide.jp/gear/origami-dripper-review) - [Coffee Starter Kit Under 10000 Yen: Everything a Beginner Needs to Start](https://coffee-guide.jp/gear/coffee-starter-kit-recommended-under-10000-yen) - [Kalita Dripper Review: All Models Compared — How to Choose and Brew](https://coffee-guide.jp/gear/kalita-dripper-review-recommended-how-to-use) --- *This is the markdown version for AI crawlers.
