📚 See all answers + explanations

  1. Q1. Matcha is a ground form of which type of green tea leaf?

    • Sencha
    • Gyokuro
    • Tencha
    • Hojicha
    Matcha is made from tencha — leaves grown in shade for 3-4 weeks before harvest to boost chlorophyll and L-theanine, then steamed, de-stemmed, de-veined and stone-ground into a fine powder.

  2. Q2. Which Japanese region is most famous for premium matcha?

    • Shizuoka
    • Uji (Kyoto)
    • Kagoshima
    • Hokkaido
    Uji, just south of Kyoto, has been producing top-grade matcha since the 12th century when Zen Buddhist monk Eisai brought tea seeds back from China and helped popularize the powdered form.

  3. Q3. What gives ceremonial-grade matcha its bright vivid green color?

    • Food coloring
    • High chlorophyll from extended shading
    • Wheatgrass blending
    • Late harvest
    Shading the tea bushes forces them to produce more chlorophyll and amino acids to capture limited light. The result is sweeter, less astringent tea and that distinctive jade-green color.

  4. Q4. Why is high-grade matcha said to give 'calm focus' rather than coffee jitters?

    • It is decaffeinated
    • L-theanine slows caffeine absorption
    • It contains theobromine like chocolate
    • It has no caffeine
    Matcha contains L-theanine, an amino acid that crosses the blood-brain barrier and promotes alpha brain waves. Combined with caffeine, it creates a smoother, longer-lasting alertness without the crash.

  5. Q5. Which utensil is used to whisk matcha in a traditional tea ceremony?

    • Chasen (bamboo whisk)
    • Chashaku spoon
    • Chawan bowl
    • Hishaku ladle
    The chasen is a bamboo whisk hand-carved from a single piece of bamboo into 80-120 fine tines. It froths matcha into a smooth foam without metal contact, which would alter the taste.

  6. Q6. What is the difference between usucha and koicha?

    • Cold vs hot matcha
    • Thin vs thick matcha preparations
    • Black vs green tea
    • Sweet vs unsweet matcha
    Usucha (thin tea) uses about 2g matcha to 70ml water and is whisked into a foamy layer. Koicha (thick tea) uses about 4g matcha to 30ml water, producing a syrupy, intense preparation reserved for formal ceremonies.

  7. Q7. Which is a red flag that you are drinking low-grade culinary matcha sold as ceremonial?

    • Yellow-brown color
    • Mild grassy aroma
    • Foam after whisking
    • Slight sweetness
    Yellow, brown or olive tones signal old, oxidized, or low-grade matcha made from late-harvest, unshaded leaves. True ceremonial matcha is vivid jade green and has a sweet, umami flavor with no harsh bitterness.

  8. Q8. A typical 1g serving of matcha contains roughly how much caffeine?

    • 5 mg
    • 30-35 mg
    • 80 mg
    • 150 mg
    One gram of matcha has about 30-35 mg of caffeine, but because you ingest the whole leaf, you also get more antioxidants (especially EGCG) than from steeped green tea.

  9. Q9. Hojicha differs from matcha mainly because hojicha is:

    • Roasted green tea
    • Fermented
    • Shaded longer
    • Mixed with black tea
    Hojicha is green tea pan-roasted at high temperature, turning the leaves reddish-brown. Roasting removes most of the caffeine and gives a toasty, caramel flavor that has become a TikTok favorite for lattes.

  10. Q10. What is the proper water temperature for whisking matcha?

    • 50 °C / 122 °F
    • 70-80 °C / 158-176 °F
    • 100 °C / 212 °F
    • Iced 5 °C / 41 °F
    Boiling water scorches matcha and brings out bitter catechins. Around 70-80 °C is the sweet spot: hot enough to dissolve the powder but cool enough to preserve the amino acids that create umami.
