Selection 2026
5
Each matcha was evaluated on 5 criteria: color, particle size, umami, packaging and value for money.
Why choose matcha
The benefits of Japanese matcha
Antioxidants, gentle energy and focus: matcha combines the benefits of green tea and coffee, without the crash or the jitters.
Rich in antioxidants
137× more EGCG than steeped green tea. These catechins neutralize free radicals and protect cells from premature aging.
Focus without jitters
L-theanine works in synergy with caffeine: heightened alertness, mental calm, without the adrenaline spikes or post-coffee crash.
Long-lasting energy
Matcha's caffeine is released gradually — stable energy for 4 to 6 hours, ideal for work, studying or exercise.
Natural detox
Chlorophyll, responsible for the vivid green color, promotes toxin elimination and supports liver function.

Buying guide
Ceremonial, classic, culinary: which one to choose?
Not all matchas are created equal — neither in taste nor in use. Understanding grades means buying right the first time.
Ceremonial
Latte, traditional bowl, pure tasting
- 1st spring harvest (April)
- Stems removed by hand
- Granite stone-ground
- Vivid jade green — zero bitterness
- Pronounced umami, silky taste
Classic
Daily latte, smoothie, mixed use
- Blend of 1st and 2nd harvest
- Shaded, balanced flavor
- Medium green color
- Slight acceptable bitterness
- Best value for money
Culinary
Cakes, pancakes, baking
- Late harvests (2nd – 3rd)
- Marked bitterness (masked in cooking)
- Olive green color, less vibrant
- Not suitable for drinking plain or in lattes
- Economical — cooking masks the flaws
Golden rule: for a latte or any drink, always choose a ceremonial grade. A culinary grade consumed plain is bitter, astringent and disappointing — even at a low price.
Buy with confidence
Quality labels & matcha certifications
Not all matchas are created equal — and labels can be misleading. Here are the certifications that truly matter before you buy.
Organic AB / EU Organic
The essential minimum
- No synthetic pesticides
- Important: you consume the whole leaf
- Issued by an EU-accredited body
- Does not guarantee ceremonial grade
- Clearspring & Bird & Blend ship to Ireland
JAS Organic (Japan)
Japanese equivalent of EU organic
- Issued by the Japanese Ministry of Agriculture
- Often more stringent than AB
- Guarantees organic Japanese origin
- Clearspring is JAS certified
- Ensures traceability at source
FSSC 22000
Independent laboratory testing
- International ISO 22000 standard
- Heavy metals & contaminants testing
- Pesticide residue testing (Eurofins)
- Matchaeologist is FSSC 22000 certified
- The most demanding certification
Uji-cha / Nishio-cha
Japanese protected designation
- Guarantees exact regional origin
- Uji-cha = Kyoto only
- Nishio-cha = Aichi region (Bird & Blend)
- Legally impossible to falsify
- Best guarantee of authenticity
Awards & recognition
Official recognition
- Japan Tea Competition (official JP)
- Clearspring: Soil Association certified
- Sign of recognized quality
- Not essential but reassuring
- Organic + grade combo = key
Direct from producer
Full traceability
- Direct farm → brand relationship
- Matchaeologist: Kyoto direct sourcing
- Postcard Teas: ships to Ireland
- No middleman trader
- Consistent quality guaranteed
The ideal trio: look for a matcha with organic (AB or JAS) + ceremonial grade + precise Japanese origin. These three criteria combined guarantee an authentic, healthy and flavorful product.
Sensory guide
How to recognize good matcha?
5 visual and sensory criteria to evaluate a matcha upon receipt — no equipment needed, in 30 seconds.
🟢 Color
Main indicator
- Good: vivid jade green, luminous
- Bad: yellow, khaki, dull
- Dull color = oxidized or old
👃 Smell
Freshness & umami
- Good: fresh, vegetal
- Bad: dusty, rancid
- Dry smell = old stock
✋ Texture
Grind fineness
- Good: ultra-fine, like talc
- Bad: grainy
- Stone-ground = <10 microns
👅 Taste
Umami vs bitterness
- Good: soft, round umami
- Bad: bitter, astringent
- Bitterness = poor grade
🧉 Foam
Sign of freshness
- Good: fine, persistent foam
- Bad: little or no foam
- No foam = low quality
Price as a final filter: an authentic ceremonial matcha cannot cost less than 20–25€ per 30 g. Below that, it's culinary grade — or worse, Chinese green tea powder with no relation to true matcha.

Everything you need to know about matcha
What is the difference between ceremonial and culinary matcha?
Ceremonial grade comes from the 1st spring harvest, with leaves de-stemmed by hand and stone-ground. The result: vivid jade green color, pronounced umami, zero bitterness. Culinary grade comes from late harvests — less aromatic, more bitter, only suitable for baking where cooking masks the flaws.
How do you recognize good matcha?
Three visual indicators: the color (vivid jade green, almost fluorescent — an olive or brown green signals oxidized or poor-quality matcha), the texture (ultra-fine, like talc — if you feel grains under your fingers, it's poorly ground), and the smell (fresh, vegetal, slightly marine — never earthy or rancid).
At what temperature should you prepare matcha?
70 to 75°C maximum. Beyond that, heat denatures the catechins (antioxidants) and accentuates bitterness. To easily reach this temperature: boil the water then let it cool for 4 to 5 minutes, or mix ⅓ cold water with ⅔ boiling water.
Can you drink matcha every day?
Yes, 1 to 2 cups per day is ideal for most healthy adults. A bowl contains approximately 35 mg of caffeine (versus 80–120 mg for an espresso) and 20 mg of L-theanine, which modulates the effects of caffeine. Avoid matcha later in the day if you are sensitive to caffeine.
Where does the best matcha in the world come from?
The Uji region (Kyoto) is the historic reference — 3 to 4 weeks of shading, rich clay soil, cultivars selected over centuries (Yabukita, Samidori). The Nishio (Aichi) and Kagoshima regions offer excellent alternatives that are often organic. Good matcha is always 100% Japanese — Chinese matchas are generally of lower taste quality.
Which matcha for a latte or smoothie?
Use exclusively a ceremonial grade. Its smoothness, umami and lack of bitterness make all the difference in a drink — milk reveals and amplifies the flaws of poor-quality matcha. For baking, however, a culinary grade is sufficient and costs two to three times less.
