How to Prepare Korean Matcha at Home
Traditional Usucha recipe, iced matcha latte, essential equipment and mistakes to avoid: the complete guide to mastering Korean matcha.
By Nico Lesage, Maison Boseong · Seoul · April 2026 · 7 min read
Korean matcha is experiencing remarkable growth internationally. Softer than its Japanese counterpart and sourced from the volcanic terroirs of Jeju Island and the mist-draped hills of Boseong, it offers a unique experience from the very first sip. The key is knowing how to prepare it properly to unlock its full aromatic potential.
1. Korean Matcha vs Japanese Matcha: What Is the Difference?
Both are finely stone-ground green tea powders from shade-grown Camellia sinensis leaves. But their terroir and flavour profiles diverge significantly.
Korean Matcha (Jeju, Boseong)
- Smooth, gently sweet flavour
- Luminous jade-green colour
- Rounded notes, low bitterness
- Ideal for beginners
- Volcanic and misty terroir
Japanese Matcha (Uji, Kyoto)
- Intense, deep umami flavour
- Vivid, highly saturated green
- Pronounced vegetal notes
- More technical to prepare
- Continental terroir, long shading
2. Essential Equipment
To prepare Korean matcha properly, four tools are essential. The fifth is optional but highly recommended for beginners.
Chawan
Wide, shallow matcha bowl with ample room for whisking.
Chasen
Bamboo whisk hand-carved from a single piece. Essential for achieving smooth froth.
Chashaku
Bamboo measuring scoop for a precise 2g portion of powder.
Fine-mesh sieve
To sift the powder and prevent stubborn clumps from forming.
Thermometer
Optional but recommended to monitor water temperature precisely.
Optional3. Traditional Usucha Recipe
Usucha (薄茶) is "thin" matcha: light, vibrant and beautifully frothy. It is the classic everyday preparation found in matcha cafés across Seoul and Jeju.
Usucha Recipe — Serves 1
Ingredients
- 1.5 to 2g of Korean matcha powder (approx. 1 chashaku)
- 80ml of filtered water at 70 to 75°C (158 to 167°F)
- 1 Preheat the bowl: pour a little hot water into the chawan, swirl gently to warm the ceramic, discard and wipe dry. This maintains the optimal temperature during preparation.
- 2 Sift the powder: pass the matcha through a fine sieve directly into the bowl. This step is crucial: it decompacts the powder and ensures a smooth, lump-free texture.
- 3 Add the water: pour 80ml of water at 70 to 75°C over the sifted powder. Water above 80°C scorches the delicate leaves, destroys their aromatic profile and releases harsh bitterness.
- 4 Whisk in a zigzag: hold the chasen loosely and whisk rapidly in a back-and-forth W or M motion. Never stir in circles. The goal is to aerate the liquid and build a fine micro-foam layer on the surface. Whisk vigorously for 20 to 30 seconds.
- 5 Enjoy immediately: Korean matcha is best savoured within 2 minutes, before the delicate foam settles and the powder sinks.
4. Iced Korean Matcha Latte Recipe
The iced matcha latte is arguably the most photographed drink in Seoul cafés right now. A refreshing, indulgent take on a Korean classic.
Iced Matcha Latte — Serves 1 large glass
Ingredients
- 2g of Korean matcha powder
- 30ml of hot water at 70°C (158°F)
- 150ml of plant-based milk (oat or almond) or whole dairy milk
- Ice cubes, generously
- 1 Make the concentrate: whisk 2g of sifted matcha with 30ml of water at 70°C until you have a perfectly smooth, lump-free paste.
- 2 Prepare the glass: fill a tall glass generously with ice, then pour in 150ml of cold milk.
- 3 Layering: slowly pour the matcha concentrate over the milk. For the signature layered look, pour over the back of a spoon to slow the flow.
- 4 Stir and enjoy: mix before drinking and enjoy immediately while cold.
5. Mistakes to Avoid
Most disappointing matcha experiences come from a handful of simple, easily avoidable errors.
Water that is too hot
Above 80°C, water scorches the delicate leaves and releases excessive bitterness that overwhelms the fine aromatic notes of the terroir.
Skipping the sieve
Matcha powder compacts naturally during storage. Without sifting, you will end up with stubborn clumps that no amount of whisking will dissolve.
Stirring in circles
Circular motion does not aerate the liquid. Only the back-and-forth W or M movement properly incorporates air and builds the signature micro-foam.
Too much powder
2g is the optimal dose. Using more does not improve flavour — it simply results in an unbalanced, bitter cup and wastes your premium matcha.
