Think you know tea? 50 expert questions on processing, ceremonies, health benefits, and global tea trade.
Tea is the world's most consumed beverage after water, with over 6 billion cups drunk every single day. From the misty mountains of Yunnan to the rolling estates of Darjeeling and the lush highlands of Sri Lanka, tea connects cultures and continents. This deep-dive quiz explores every dimension of Camellia sinensis — the single plant species behind white, green, oolong, black, pu-erh, and yellow teas — as well as the ceremonies, trade history, chemistry, and global economics that have shaped a 5,000-year-old industry.
Each round presents 10 randomized questions from the pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the six classes of true tea and how oxidation level determines each, legendary varieties like Silver Needle and Da Hong Pao, the Japanese chanoyu and Chinese gongfu traditions, the Boston Tea Party and the Opium Wars, caffeine and L-theanine content across types, top tea-producing nations, and the science behind why a 350-year-old Da Hong Pao bush can fetch $1,400 per gram.
Both green and black tea come from Camellia sinensis, but differ entirely in processing. Green tea leaves are quickly heated — pan-fired in China or steamed in Japan — immediately after picking to stop enzymatic oxidation, preserving their green colour and grassy flavour. Black tea leaves are fully oxidised (85–100%), turning the leaves dark brown and developing richer, bolder flavours. Oxidation also converts some catechins into theaflavins and thearubigins, reducing antioxidant content compared to green tea.
Da Hong Pao (Big Red Robe), a heavily oxidised oolong from the Wuyi Mountains of Fujian, China, is considered the world's most expensive tea. Leaves from the original four surviving 350-year-old mother bushes have sold for up to $1,400 per gram. The Chinese government stopped harvesting these mother bushes in 2006 to preserve them, making authentic first-generation Da Hong Pao essentially priceless. Modern Da Hong Pao sold commercially is cloned from these original plants.
Both have distinct benefits. Tea contains L-theanine, an amino acid that promotes calm alertness and modulates caffeine's effects, resulting in a smoother energy curve than coffee. Green tea is rich in EGCG (epigallocatechin gallate), a potent antioxidant linked to reduced inflammation and cancer-cell inhibition in laboratory studies. Coffee generally contains more caffeine and has strong links to reduced risk of Parkinson's disease and type 2 diabetes. Neither beverage is universally superior — both contribute positively to health when consumed without excessive sugar or cream.
