Types of Teas and Their Properties

The differences in teas are determined by how they are processed after harvesting. Each method influences not only taste, but also how the tea affects the mind and body.

Green Tea

Green tea is quickly steamed or pan-fired to stop oxidation, preserving its fresh, grassy flavor. This method keeps L-theanine, an amino acid that promotes relaxation without drowsiness, intact while retaining moderate caffeine. The result is gentle alertness and calm focus—ideal for the morning or early afternoon to start the day or power through a work session.

Matcha Tea

A powdered green tea, matcha is shade-grown, carefully harvested, steamed, dried, and stone-ground into a fine powder. Unlike steeped teas, matcha uses powdered whole leaves, providing higher concentrations of L-theanine, caffeine, and catechins, which support sustained attention, calm, and mental clarity—excellent for focused work, study, or meditation.

Black Tea

Black tea is fully oxidized. After withering and rolling, the leaves darken and develop bold flavors, then are gently heated to stop oxidation and remove moisture. This process increases caffeine availability, producing a stimulating yet balanced effect that enhances alertness and keeps the mind engaged without overstimulation.

Oolong Tea

Oolong tea is partially oxidized, combining the freshness of green tea with the depth of black tea. Its moderate caffeine and retained L-theanine create a state of relaxed alertness, perfect for focused, mindful work.

White Tea

Minimally processed, white tea is withered and dried, so it contains lower caffeine levels and delicate polyphenols, producing a subtle, soothing effect on the nervous system. It’s well-suited for an afternoon break or a relaxing evening brew.

Pu-erh Tea

Pu-erh tea is fermented and aged, developing earthy, grounding flavors. Its unique microbial fermentation is believed to aid digestion and support steady concentration, making it a good choice for post-meal focus or quiet, contemplative tasks.
