What actually happens
A description of something people do now, compiled from published accounts rather than from practice.
A host prepares and serves matcha to a small number of guests in a space arranged for the occasion. The scroll, the flowers, the utensils, the sweets and the sequence of movements are all chosen and are all part of the event; the whisking itself occupies a small proportion of it. A full formal gathering runs for hours and includes a meal, while an abbreviated form serving thin tea alone is far more commonly encountered.
Thick tea and thin tea are different preparations

Koicha, thick tea, uses a much larger quantity of high-grade matcha kneaded rather than whisked into a paste-like consistency, and is conventionally shared from one bowl. Usucha, thin tea, is the lighter whisked preparation most people have encountered. They occupy different positions in a gathering and are not interchangeable.
What outside accounts tend to get wrong
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Three things recur. That it is primarily a religious ritual — the relationship with Zen is real and is not the whole of it, and practitioners are not necessarily religious. That there is one correct form — schools differ, and a detail true of one may be wrong for another. And that matcha lattes or café matcha are ceremonial — they are unrelated preparations, and the grade language borrowed from this practice is marketing rather than a defined standard.
The four principles, and how they are usually mistranslated
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Practitioners frequently summarise the practice with four terms conventionally rendered as harmony, respect, purity and tranquillity. Outside writing tends to present these as a philosophy that explains the practice. They are better understood as a summary formulated within the tradition, and the English renderings are approximations that carry connotations the Japanese terms do not.
