Tencha (Tea Leaves for Matcha)

What is Tencha?

Think of tencha as matcha's raw form—it's essentially matcha before it gets ground into that fine, vibrant powder we all know and love. Tencha refers to the specially processed tea leaves that serve as the sole ingredient for authentic matcha. Without tencha, there would be no matcha, making it one of the most important elements in Japanese tea culture.

The word "tencha" literally means "grinding tea" in Japanese, which gives you a pretty clear hint about its purpose. These aren't your regular tea leaves—they're the result of an incredibly meticulous growing and processing method that's been refined over centuries.

How Tencha is Grown and Processed

What makes tencha special starts long before harvest. The tea plants are shade-grown for about 3-4 weeks before picking, covered with traditional bamboo screens or modern shade cloths. This shading process is crucial—it forces the plants to produce more chlorophyll and amino acids (especially L-theanine) while reducing tannins that can make tea bitter.

After harvest, the processing gets really interesting. Unlike regular green tea, tencha leaves aren't rolled or shaped. Instead, they're steamed immediately to stop oxidation, then air-dried in special ovens. The stems and veins are carefully removed, leaving only the pure leaf tissue. This creates those flat, crumbly pieces that look nothing like traditional tea leaves.

The Shade-Growing Advantage

That shading period isn't just for show—it's what gives tencha (and eventually matcha) its incredible nutritional profile and that distinctive umami flavor. The stress of reduced sunlight triggers the plant to concentrate its nutrients, resulting in higher levels of antioxidants, chlorophyll, and amino acids.

From Tencha to Matcha

Here's where the magic happens: tencha becomes matcha through stone grinding. Traditional granite stone mills slowly grind the dried tencha leaves into the ultra-fine powder we recognize as matcha. This process takes time—about an hour to produce just 30 grams of matcha powder.

The quality of the original tencha directly impacts the final matcha quality. Premium tencha from the first flush (first harvest of spring) creates ceremonial grade matcha, while later harvests might become culinary grade matcha.

Quality Grades of Tencha

Not all tencha is created equal. The highest quality tencha comes from:

• First flush leaves: The youngest, most tender leaves picked in early spring
• Proper shading: Full 3-4 weeks of shade coverage
• Careful processing: Immediate steaming and gentle drying
• Expert sorting: Complete removal of stems and veins

At Matcha & CO, we source our tencha from renowned tea gardens in Japan that follow these traditional methods, ensuring that every batch of our matcha starts with premium-quality tencha leaves.
