Blue Matcha's Floral Origin: The Butterfly Pea Flower
Unlike traditional matcha, which is derived from the green tea plant (Camellia sinensis), what is blue matcha made of? The answer is the Clitoria ternatea plant, more commonly known as the butterfly pea flower. This perennial climbing plant is indigenous to tropical and subtropical climates across Southeast Asia, including Thailand, Malaysia, and Vietnam. For centuries, the flowers of this plant have been used for both culinary and medicinal purposes in traditional Southeast Asian medicine, prized for their striking blue color and health properties.
To produce the fine blue powder, the process involves carefully hand-picking the fresh flowers, which are then dried, traditionally in the sun to preserve their color and nutrients. Once dried, the petals are micro-milled into a fine, silky powder that is highly soluble, making it easy to whisk or blend into a variety of foods and drinks. This manufacturing method is what likens it to green matcha, despite the two originating from entirely different plant species. The deep blue color comes from potent antioxidant compounds called anthocyanins, the same pigments found in foods like blueberries and red cabbage.
The Alluring Color-Changing Phenomenon
One of the most captivating features of blue matcha is its ability to magically change color. The anthocyanins responsible for the deep blue are highly sensitive to changes in pH levels.
- Add an acid: When you introduce an acidic ingredient, such as lemon or lime juice, the powder’s color transforms from blue to a vibrant purple or pink.
- Add a base: Mixing it with milk or other neutral or basic liquids will maintain the beautiful indigo shade, which is perfect for visually stunning lattes.
This natural, pH-reactive property makes blue matcha a popular ingredient for bartenders, chefs, and home cooks looking to create eye-catching, naturally colored cocktails, lemonades, or baked goods.

From a wellness perspective, blue matcha's naturally high antioxidant content is a major draw. The anthocyanins help combat free radicals and may support cognitive function and healthy skin. Its caffeine-free nature is ideal for anyone seeking a relaxing and calming beverage to enjoy at any time of day, including the evening.
