What Is Matcha Powder?
Matcha powder has rapidly grown in popularity across the UK wellness market and for good reason. Unlike regular green tea, matcha delivers a concentrated source of antioxidants, calm energy, and mental clarity in every cup.
But what exactly is matcha powder? Is ceremonial grade worth it? How much caffeine does matcha contain? And how do you choose the best matcha powder in the UK?
This complete guide covers everything you need to know.
Matcha powder is a finely ground green tea made from specially grown tea leaves called tencha. Unlike traditional green tea—where leaves are steeped in hot water and then discarded—matcha involves consuming the entire tea leaf. This method delivers a more concentrated source of beneficial compounds, including antioxidants (particularly EGCG), L-theanine, chlorophyll, and natural caffeine.

Origins and Historical Significance
Matcha has deep roots in Japan, where it became central to Zen Buddhist practices and traditional tea ceremonies. Monks originally used matcha to support calm alertness during long meditation sessions. Over time, it evolved into a refined cultural ritual, valued not only for its taste but also for its mental and physical benefits.
The Shade-Growing Process
What sets matcha apart begins long before harvest. Several weeks prior to picking, tea plants are covered with shade cloths to limit sunlight exposure. This process slows growth and triggers the plant to produce higher levels of chlorophyll and L-theanine.
- Increased chlorophyll gives matcha its vibrant green color
- Elevated L-theanine contributes to smoother energy and reduced caffeine jitters
From Tencha to Matcha: Stone Grinding
After harvesting, the leaves are steamed to prevent oxidation, dried, and stripped of stems and veins to create tencha. These leaves are then slowly ground using traditional stone mills. This low-heat grinding method preserves delicate nutrients and results in the ultra-fine powder known as matcha.
Why Matcha Is More Nutrient-Dense Than Green Tea
Because matcha is consumed whole rather than infused, you absorb everything the leaf contains. This means a single serving delivers significantly more antioxidants and amino acids than brewed green tea. The combination of natural caffeine and L-theanine creates a balanced, sustained energy that differs from the sharper spike often associated with coffee.
In essence, matcha powder is not just green tea in powdered form—it’s a carefully cultivated, traditionally prepared tea designed to maximize both flavor and nutritional value.
Matcha Benefits
Matcha is known for delivering a wide range of physical and mental benefits, largely due to its unique combination of natural caffeine, L-theanine, and concentrated antioxidants. Because you consume the entire leaf, these benefits tend to be more noticeable and longer-lasting than those from regular green tea.
1. Sustained Energy & Focus (Without the Crash)
One of matcha’s most well-known benefits is its ability to provide calm, sustained energy.
Matcha naturally contains caffeine, but it also delivers high levels of L-theanine, an amino acid that influences how caffeine affects the brain. L-theanine promotes alpha brain wave activity, which is associated with relaxed alertness. This means caffeine is released more gradually into the bloodstream rather than all at once.
As a result, matcha energy is:
- Slower to release
- Longer lasting
- Less likely to cause jitters or crashes
Instead of sharp spikes and sudden fatigue, many people describe matcha as producing steady focus and mental clarity, making it popular for work, studying, and meditation.

2. High Antioxidant Content (EGCG Explained)
Matcha is exceptionally rich in antioxidants, particularly epigallocatechin gallate (EGCG), a catechin linked to cellular protection.
Because matcha leaves are shade-grown, they produce more catechins as a defense mechanism. When the leaves are stone-ground and consumed whole, these antioxidants are absorbed directly rather than partially extracted through steeping.
Potential benefits of EGCG include:
- Neutralizing free radicals
- Supporting cellular health
- Helping protect against oxidative stress
This antioxidant density is one of the main reasons matcha is often considered more potent than traditional green tea.
3. Metabolism & Fat Oxidation Support
Matcha may support metabolism by enhancing the body’s ability to burn fat more efficiently. Research on green tea catechins suggests they can help increase thermogenesis—the process by which the body burns calories to produce heat.
Because matcha delivers higher concentrations of these compounds, it is often used as part of:
- Morning routines
- Pre-workout beverages
- Weight management strategies
While matcha is not a standalone solution, it can complement an active lifestyle and balanced diet.
4. Mood & Stress Support
The same L-theanine that enhances focus also plays a role in mood regulation and stress response. L-theanine supports neurotransmitters associated with relaxation, such as GABA, dopamine, and serotonin.
This may help:
- Reduce feelings of stress or overstimulation
- Improve emotional balance
- Support calm mental clarity during busy or demanding days
Unlike stronger stimulants, matcha tends to feel grounding rather than overwhelming.
5. A Gut-Friendly Alternative to Coffee
For individuals sensitive to coffee, matcha is often easier on the digestive system.
Compared to coffee, matcha:
- Is less acidic
- Contains compounds that support a smoother caffeine release
- Is less likely to trigger stomach irritation or acid reflux
Because it also contains natural fiber from the whole leaf, matcha can feel gentler while still providing energy.
Matcha vs Coffee vs Green Tea
| Feature | Matcha | Coffee | Green Tea |
|---|---|---|---|
| Caffeine release | Slow & steady | Fast spike | Moderate |
| L-theanine | High | None | Low |
| Antioxidant level | Very high | Low | Moderate |
| Acidity | Low | High | Low |
| Energy crash | Unlikely | Common | Rare |
Matcha offers a more concentrated nutritional profile.
Matcha Caffeine: How Much Is in Matcha?
One serving (about 1 gram) of matcha typically contains ~60–70 mg of caffeine. This places matcha between coffee and traditional green tea in terms of caffeine strength—but the experience it delivers is very different.
For comparison:
- Coffee: ~90–120 mg
- Green tea: ~20–40 mg
The key distinction isn’t just how much caffeine matcha contains, but how the caffeine behaves in the body.
How L-Theanine Slows Caffeine Absorption
Matcha naturally contains L-theanine, an amino acid that alters caffeine absorption and brain response. Instead of caffeine entering the bloodstream rapidly (as it does with coffee), L-theanine promotes a gradual release.
This happens because L-theanine:
- Modulates neurotransmitter activity
- Encourages relaxed alertness rather than stimulation
- Slows the absorption curve of caffeine
As a result, energy feels smoother and more controlled, often lasting several hours without a sharp rise or fall.
Why Matcha Causes Less Cortisol Spike
Caffeine from coffee can trigger a noticeable cortisol response, especially when consumed on an empty stomach. Cortisol is the body’s primary stress hormone, and repeated spikes may contribute to jitters, anxiety, and crashes.
Matcha tends to produce a lower cortisol response because:
- L-theanine counterbalances stimulant effects
- Caffeine release is slower and steadier
- There is less sudden nervous system activation
This makes matcha feel more grounding and less stressful for many people, particularly those sensitive to stimulants.
Who Should Be Cautious With Matcha
While matcha is generally well tolerated, it may not be suitable for everyone.
You may want to limit or avoid matcha if you:
- Are extremely sensitive to caffeine
- Have anxiety disorders aggravated by stimulants
- Are pregnant or advised to restrict caffeine
- Have iron deficiency (matcha may reduce iron absorption when taken with meals)
In these cases, lower doses or occasional use is often more appropriate.
Safe Daily Intake of Matcha
Most healthy adults can safely consume 1–2 servings of matcha per day without adverse effects. This typically equals:
-
60–140 mg of caffeine daily
For comparison, general caffeine guidelines suggest staying below 400 mg per day from all sources combined.
To reduce potential side effects:
- Avoid consuming matcha late in the day
- Start with smaller servings if new to matcha
- Do not stack matcha with other high-caffeine drinks
Why Matcha Caffeine Feels Different
In summary, matcha doesn’t just deliver caffeine it delivers it intelligently. The presence of L-theanine creates a unique balance of alertness and calm, helping reduce crashes, jitters, and stress-related responses.
This caffeine profile is a major reason matcha is favored for sustained focus, mindful routines, and daily wellness practices rather than short bursts of stimulation.
Ceremonial Grade Matcha vs Culinary Grade
Understanding matcha grades is essential when choosing the right matcha powder—especially in the UK market, where quality and pricing can vary significantly. While both types come from the same tea plant, their cultivation, taste, and intended use are very different.
Ceremonial Grade Matcha
Ceremonial grade matcha represents the highest quality available and is traditionally used for drinking on its own.
Key characteristics:
- Bright, vibrant green color
- Smooth texture with a naturally sweet, umami-rich taste
- Minimal bitterness
- Best enjoyed plain with hot water
This grade is made from the youngest, most delicate leaves and carefully stone-ground to preserve flavor and nutrients.
Our ceremonial grade matcha is carefully sourced and stone-ground to preserve vibrant colour, smooth texture, and authentic flavour.
Culinary Grade Matcha
Culinary grade matcha is designed to be mixed with other ingredients.
Key characteristics:
- Slightly darker green color
- Stronger, more robust flavor
- Noticeable bitterness (which holds up well in recipes)
- Ideal for lattes, smoothies, desserts, and baking
Because it’s blended with milk, sweeteners, or other ingredients, the stronger taste becomes an advantage rather than a drawback.
If you enjoy creative drinks and blends, discover our range of coloured matcha blends ideal for lattes, smoothies, and vibrant recipes.
Price Differences in the UK Market
In the UK, price is often the clearest indicator of grade.
- Ceremonial grade: typically higher priced due to hand-harvesting, limited yields, and traditional stone grinding
- Culinary grade: more affordable and widely available
Ceremonial matcha is often sold in smaller tins to maintain freshness, while culinary matcha is commonly available in larger quantities for everyday use.
When Not to Buy Ceremonial Grade
Despite its premium status, ceremonial grade is not always the best choice.
Avoid using ceremonial grade matcha if:
- You plan to make matcha lattes with milk and sweeteners
- You’re baking or cooking with heat
- You’re new to matcha and still developing your palate
- Budget is a concern
Using ceremonial grade in recipes can mask its subtle flavor, making the extra cost unnecessary.
Storage Tips for Matcha Powder
Proper storage is critical for preserving matcha quality.
Best practices include:
- Store in an airtight container
- Keep away from light, heat, and moisture
- Refrigerate after opening (especially ceremonial grade)
- Allow the container to reach room temperature before opening to prevent condensation
Oxygen and light are the main causes of flavor and color degradation.
Shelf Life: What to Expect
Matcha does not age like wine — it declines over time.
- Unopened matcha: typically stays fresh for up to 6–12 months
- Opened matcha: best consumed within 1–2 months for optimal flavor
- Ceremonial grade degrades faster due to its delicate profile
Dull color, bitterness, and flat taste are signs that matcha has passed its peak.
Quick Comparison: Ceremonial vs Culinary Matcha
| Feature | Ceremonial Grade | Culinary Grade |
|---|---|---|
| Color | Bright, vibrant green | Slightly darker green |
| Taste | Smooth, slightly sweet | Strong, more bitter |
| Best use | Drinking plain | Lattes, smoothies, baking |
| UK price range | Higher | More affordable |
| Shelf life after opening | Shorter | Slightly longer |
How to Prepare Matcha Properly
Preparing matcha correctly makes a noticeable difference in taste, texture, and overall experience. Unlike regular tea, matcha requires a short but intentional preparation process to fully dissolve the powder and release its flavor.
Basic Matcha Preparation (Traditional Method)
-
Sift 1g of matcha into a bowl
Sifting removes clumps and ensures a smooth, lump-free texture. -
Add 70–80 ml of hot water
Use water heated to 70–80°C (not boiling). Boiling water can scorch the matcha and cause bitterness. -
Whisk in a zig-zag (M or W) motion
Use a bamboo whisk and whisk briskly until a fine foam forms on the surface. -
Drink immediately
Matcha is best enjoyed fresh, while the foam and flavor are at their peak.
For matcha lattes, whisk first, then add warm milk or a milk alternative after the matcha is fully dissolved.
Why Water Temperature Matters
One of the most common mistakes with matcha is using water that is too hot.
- Water above 85°C can increase bitterness
- Cooler water preserves sweetness and umami
- Proper temperature protects delicate amino acids like L-theanine
If you don’t have a thermometer, let freshly boiled water sit for 5–7 minutes before pouring.
Tools That Improve Matcha Quality (But Aren’t Mandatory)
While matcha can be prepared with basic kitchen tools, traditional utensils improve consistency.
Helpful tools include:
- Bamboo whisk (chasen): creates smooth foam without clumping
- Matcha bowl (chawan): allows proper whisking motion
- Fine mesh sifter: prevents clumps
If needed, a small electric frother can be used, but it may produce larger bubbles compared to a whisk.
Common Matcha Preparation Mistakes
Avoid these issues for best results:
- Skipping the sifting step
- Using boiling water
- Stirring instead of whisking
- Letting matcha sit too long before drinking
These mistakes can lead to bitterness, gritty texture, or flat flavor.
Latte Preparation Tips
When making matcha lattes:
- Always dissolve matcha with water before adding milk
- Use unsweetened milk to taste matcha clearly
- Sweeten lightly if needed—ceremonial grade often requires less
This method ensures the matcha remains smooth and evenly blended.
Best Time to Drink Matcha
Timing plays an important role in how matcha feels and performs in the body. Because matcha contains both caffeine and L-theanine, when you drink it can influence energy, focus, and sleep quality.
Morning: A Coffee Replacement
Drinking matcha in the morning is one of the most popular choices, especially for those looking to reduce coffee intake.
Why morning works well:
- Provides gentle, sustained energy without a sharp spike
- Supports focus and mental clarity for the day ahead
- Typically causes less stomach irritation than coffee
Many people prefer matcha after a light breakfast rather than on a completely empty stomach to avoid overstimulation.
Early Afternoon: Focus Without the Crash
Matcha is well suited for the early afternoon, when energy and concentration often dip.
Benefits of afternoon matcha:
- Helps restore focus without disrupting productivity
- Less likely to cause an energy crash compared to coffee
- Supports calm alertness for meetings, study, or creative work
This timing makes matcha a useful alternative to sugary snacks or strong stimulants.
Before Workouts: Natural Stimulation
Matcha can also be consumed 30–60 minutes before exercise.
Why it works pre-workout:
- Provides steady energy rather than a sudden surge
- May support fat oxidation due to catechins
- L-theanine can help improve mental focus during training
This makes matcha a good option for those who find traditional pre-workout drinks too intense.
When to Avoid Matcha
If you’re sensitive to caffeine, timing becomes especially important.
You may want to avoid matcha:
- In the late afternoon or evening
- Within 6–8 hours of bedtime
- When already consuming multiple caffeine sources
Even though matcha is gentler than coffee, it can still interfere with sleep for caffeine-sensitive individuals.
Finding Your Ideal Timing
The best time to drink matcha ultimately depends on your:
- Caffeine tolerance
- Daily routine
- Sleep sensitivity
Start with earlier in the day and adjust gradually based on how your body responds.
How to Choose the Best Matcha Powder in the UK
Choosing high-quality matcha is especially important in the UK market, where freshness, sourcing, and storage conditions can vary widely. Understanding what to look for helps you avoid low-grade powders and ensures you get the full flavor and benefits matcha is known for.
1. Look for Clear Origin Transparency (Japan Preferred)
Authentic, high-quality matcha should clearly state its country of origin. Japan is widely regarded as the gold standard for matcha production due to:
- Traditional cultivation methods
- Shade-growing practices
- Strict quality control
Regions within Japan are known for producing premium tencha, which is then stone-ground into matcha. If the label doesn’t clearly state origin, quality is often inconsistent.
2. Check the Colour: Bright Green Is Key
Colour is one of the easiest quality indicators.
High-quality matcha:
- Appears bright, vibrant green
- Indicates high chlorophyll content
- Signals freshness and proper storage
Avoid powders that look:
- Dull
- Yellow-green
- Brownish
These colours often indicate oxidation, age, or lower-grade leaves.
3. Texture Should Be Fine and Silky
Good matcha is stone-ground into an ultra-fine powder.
What to look for:
- Smooth, talc-like texture
- No visible granules
- Easily blends with water when whisked
- Grainy or coarse textures often mean the matcha was machine-ground, which can generate heat and degrade flavor.
4. Taste Profile: Smooth, Not Bitter
Quality matcha should taste:
- Smooth
- Mildly sweet
- Umami-rich
Excessive bitterness usually indicates:
- Lower-grade leaves
- Overexposure to sunlight during growth
- Old or improperly stored powder
Bitterness can be acceptable in culinary-grade matcha, but it should still be balanced rather than harsh.
5. Packaging Matters (Especially in the UK Climate)
Matcha is sensitive to light, air, heat, and moisture all common issues in long supply chains.
Choose matcha that is:
- Sealed in airtight tins or foil-lined pouches
- Stored away from direct light
- Clearly labeled with a best-before date
Once opened, refrigeration is recommended to preserve freshness.
6. Price as a Quality Signal (Not a Guarantee)
While price alone doesn’t guarantee quality, extremely cheap matcha is often a red flag.
In the UK market:
- Higher-quality matcha typically costs more due to import, storage, and handling
- Very low prices often indicate bulk, low-grade powder
Focus on value and transparency, not just cost.
