What is Arteao's Organic Matcha?

More bitter, more healthy. Less bitter, more relaxing.

Try Arteao's optimized flavor and health profile matcha


  • COLOR: Deeper  →  Lighter
  • CATECHIN: (Bitterness) Lower  →   Higher
  • L-THEANINE: (Umami) Higher  →  Lower

From left to right shows the various grades of matcha. The left is higher in L-theanine and the right is higher in catechins. High quality matcha is usually hand picked and is the first harvested tea of the year. Arteao's organic matcha is hand picked by local farmers and has an optimized flavor and health profile with balanced L-theanine and catechin levels. 


    Traditional Process

    Covering the Tea Fields

    Hand Picking

    Stone Milling

    4-6  weeks before harvest, the tea plants are covered with a straw net to avoid direct sun light. This is a unique process seen in the cultivation of matcha. This process boosts the amino acid content (l-theanine, umami) of the leaves, making bitterness milder and giving the plant a deeper green color.

     The difference between hand picking and machine harvesting is that skilled farmers are picking the best leaves of the plant. Machine harvesting does not give you this ability to separate the best leaves from the others. 

    Arteao's Organic Matcha is ground by traditional Japanese stone milling (Mikage-ishi) extremely slow at 1 - 1.5 oz (30 - 40 g) per hour. This process avoids heat and friction that destroy the nutrients of the leaf and deteriorate the color and flavor. 



    Health Benefits


    A strong anti-oxidant found in green tea linked to fight free radicals. The most abundant green tea catechin is called (-)-epigallocatechin 3-gallate (EGCG) and is a highly active area of scientific research. Tea catechins such as EGCG have cancer-preventing functions, lowers blood pressure, anti-infection properties, immune system stimulation, and aids in dieting by suppressing hunger.


    An amino acid (umami) found in green tea induces the generation of alpha brain waves that are considered to be an index of relaxation and stress reduction. L-theanine is also known to control the excitement caused by caffeine. 




    Energy Level

    Matcha contains caffeine but, it’s about half the amount of a regular cup of coffee. The caffeine in matcha is absorbed slowly in the body, giving you a long and sustained energy boost compared to coffee.
