• Clumping in organic matcha is typically caused by moisture exposure, static electricity, or whisking technique. Simple fixes like sifting, proper storage, and using a bamboo whisk can prevent most clumps. If clumping persists, the matcha may be too old or stored improperly, so consider replacing it.
• Moisture is the main culprit—store matcha in an airtight container away from humidity.
• Always sift matcha before whisking to break up any clumps.
• Use a bamboo whisk (chasen) with a gentle zigzag motion, not a circular stir.
• Water temperature should be around 175°F (80°C)—too hot causes clumping.
• If matcha is old or smells dull, it's time for a fresh tin.
