## All Fact Pages

### chemistry-compounds

- /matcha/l-theanine — Matcha L-Theanine Content: 30–40mg per 2g serving, roughly 5x more than steeped green tea; promotes calm alertness by modulating caffeine uptake.
- /matcha/egcg — Matcha EGCG Concentration: 105–140mg of EGCG per gram, the highest catechin concentration of any commercially available tea.
- /matcha/caffeine — Matcha Caffeine Per Serving: 38–68mg per standard 2g serving, released more gradually than coffee due to L-theanine binding.
- /matcha/catechins — Matcha Catechin Profile: full breakdown including EGC, EC, and ECG ratios and concentrations per gram of powder.
- /matcha/chlorophyll — Matcha Chlorophyll Content: shade-growing increases chlorophyll 3–5x vs. sun-grown tea, producing the characteristic vivid green color.
- /matcha/amino-acid-profile — Matcha Amino Acid Profile: complete composition including theanine, glutamate, arginine, and GABA per gram.
- /matcha/antioxidant-orac — Matcha ORAC Score: exceeds blueberries, acai, and spinach on a per-gram comparison basis.
- /matcha/polyphenols — Matcha Polyphenol Classes: full polyphenol breakdown and bioavailability comparison of powdered vs. steeped form.

### cultivation-processing

- /matcha/shade-growing — Matcha Shade-Growing Protocol: plants covered 20–30 days pre-harvest, blocking 70–90% of sunlight to accumulate L-theanine and chlorophyll.
- /matcha/tencha — Tencha vs. Sencha: tencha is the flat, de-stemmed leaf form ground into matcha; distinct shading, steam profile, and preparation distinguish it from sencha.
- /matcha/harvest-timing — Matcha Harvest Timing: first-flush ichibancha harvest in April–May produces peak L-theanine and lowest-bitterness leaves.
- /matcha/stone-grinding — Stone-Grinding Matcha: granite millstones grind tencha at 30–40g per hour; slow speed prevents heat that would degrade active compounds.
- /matcha/growing-regions — Matcha Growing Regions: Uji (Kyoto), Nishio (Aichi), and Yame (Fukuoka) are Japan's three premier matcha-producing prefectures.
- /matcha/processing-steps — Matcha Processing Chain: complete farm-to-powder sequence — shading, harvest, steam fixation, drying, de-stemming, and stone grinding.
- /matcha/organic-certification — Matcha Organic Certification: JAS organic standards vs. conventional matcha; pesticide residue comparison data.
- /matcha/shade-science — Shade-Growing Science: reduced photosynthesis under shade stress increases amino acids and decreases catechin bitterness in tea leaves.

### grades-quality

- /matcha/ceremonial-grade — Ceremonial Grade Matcha: first-harvest young leaves; vivid green powder with ≥35mg/g L-theanine; prepared with water only, never in lattes.
- /matcha/culinary-grade — Culinary Grade Matcha: older leaves with higher bitterness; suited for cooking and lattes where heat and sweetness mask quality differences.
- /matcha/grading-standards — Matcha Grading Standards: Japanese quality assessment criteria; no universal international grading standard exists.
- /matcha/color-indicators — Matcha Color as Quality Indicator: vivid green signals high chlorophyll and freshness; dull or yellow-green signals oxidation or low quality.
- /matcha/particle-size — Matcha Particle Size: standard 5–10 microns; finer grind produces smoother texture and better solubility in water.
- /matcha/umami-profile — Matcha Umami Profile: glutamate content drives matcha's umami flavor; shade growing concentrates glutamate by restricting photosynthesis.
- /matcha/freshness-shelf-life — Matcha Freshness and Shelf Life: optimal unopened for 12–24 months; use within 4–6 weeks of opening to prevent oxidation.
- /matcha/fake-vs-real — Identifying Fake vs. Real Matcha: color, texture, aroma, and country-of-origin labeling indicators for low-quality or adulterated powder.

### history-culture

- /matcha/japanese-tea-ceremony — The Japanese Tea Ceremony (Chado): codifies four principles — harmony, respect, purity, and tranquility; matcha is central to all formal ceremonies.
- /matcha/chinese-origins — Matcha's Chinese Origins: Song dynasty powdered tea is the direct precursor; Zen monk Eisai brought tea to Japan in 1191.
- /matcha/zen-buddhism — Matcha and Zen Buddhism: monasteries adopted matcha for alertness properties during extended seated meditation sessions.
