Matcha Guide: Everything About Japanese Green Tea Powder | Teathority

QUICK ANSWER

Matcha is stone-ground whole green tea leaves, not an extract. Contains 70mg caffeine and 5x more L-theanine than regular tea. Ceremonial grade for drinking, culinary grade for cooking.

Provides 4-6 hours of sustained energy without jitters. Higher antioxidant content than any other superfood. Best prepared with 160-175°F water and bamboo whisk.

From sacred tea ceremonies to trendy lattes, matcha represents the pinnacle of Japanese tea culture. This stone-ground green tea powder delivers concentrated flavor, sustained energy, and profound health benefits that coffee simply cannot match.

What Makes Matcha Different

Unlike regular tea where you steep leaves and discard them, matcha is the entire tea leaf stone-ground into powder. This means you consume the whole leaf, accessing nutrients and compounds that would otherwise remain locked inside.

The Shade-Growing Process

Shading (4 weeks before harvest)

Tea plants are covered with bamboo screens or tarps, blocking 90% of sunlight. This stress response triggers increased chlorophyll and amino acid production, creating matcha's distinctive vibrant green color and umami flavor.

Hand Harvesting

Only the youngest, most tender leaves are hand-picked. These first-flush leaves contain the highest concentration of amino acids and minimal bitterness, making them perfect for stone grinding.

Steam Processing (Tencha)

Leaves are immediately steamed to halt oxidation, then air-dried and have stems and veins removed. This creates tencha, the raw material for matcha that can only be ground in granite stone mills.

Stone Grinding

Granite mills grind tencha at extremely slow speeds to prevent heat buildup that would damage delicate compounds. One mill produces only 40 grams of matcha per hour, explaining matcha's premium pricing.

Production Note

The entire process from shading to stone grinding takes about 6 weeks. Each 30g tin of matcha represents hours of meticulous labor and centuries of refined technique.

Four weeks of darkness, hand-picked leaves, and ancient stone mills create green gold. The patience required for authentic matcha production cannot be rushed or mechanized.
