Matcha, a finely ground powder of specially grown and processed green tea leaves, is becoming increasingly popular worldwide, particularly in the U.S. The beverage is being marketed on social media platforms like TikTok for its unique taste, vibrant green color, and health benefits such as lower caffeine and higher L-theanine content compared to coffee. The trend, known as 'Matcha-core', involves incorporating the green hue into fashion and accessories. With matcha's rising demand, its supply is struggling to keep up. South Korea is also seeing a variety of new matcha products hitting the market. While matcha does have caffeine, it is generally lower than coffee. However, people sensitive to caffeine or with certain health conditions should consume it cautiously. Matcha's origins date back to the Tang Dynasty in China, and it became part of Japanese culture through the tea ceremony.
