Koicha is a thick style of matcha made with more tea powder and less hot water, resulting in a rich, smooth consistency.
It is the central part of a formal chaji and is prepared using high-quality matcha with a naturally mellow flavor.
Traditionally, all guests shared a single bowl of koicha, each taking a sip in turn as an expression of harmony, mutual respect, and the spirit of gathering together.
Since the COVID-19 pandemic, however, many tea practitioners and organizations have adopted individual bowls for each guest as a hygiene measure.
While this practice differs from the traditional style, it has become increasingly common at many tea gatherings today.
