Does Matcha Have Pesticides?

Matcha can contain pesticide residues, just like other agricultural products.

But there’s an important distinction between pesticides being used during farming and a food containing pesticide residues at unsafe levels.

Conventional Japanese tea farmers may use agricultural chemicals to protect tea plants from insects, disease and other pressures. Japan also regulates the residues that can remain in food.

So if you’ve discovered that pesticides are sometimes used to grow Japanese matcha, that fact alone isn’t a reason to assume the matcha is unsafe.

Here’s what you need to know.

Are Pesticides Used to Grow Matcha?

Yes.

Pesticides can be used in conventional Japanese tea cultivation.

Tea is an agricultural crop. Like other crops, tea plants can be affected by insects, disease and other pressures, so conventional growers may use agricultural chemicals permitted for tea cultivation.

Certified organic tea is produced under a different set of requirements that restrict the substances and farming methods that can be used.

But this doesn’t mean:

Conventional = unsafe

or:

Organic = pesticide-free

The reality is more nuanced.

Should You Be Worried About Pesticides in Japanese Matcha?

The word “pesticide” can sound alarming, but pesticide use and unsafe pesticide exposure are not the same thing.

Japan regulates agricultural chemical residues in food through its Positive List System.

Maximum Residue Limits, known as MRLs, are established for agricultural chemical residues in different foods. Food containing residues above the applicable MRL cannot be distributed.

Japan also generally applies a uniform limit of 0.01 ppm to agricultural chemicals for which a specific residue standard has not been established, although there are exemptions and substances subject to different rules.

This doesn’t mean Japanese matcha is pesticide-free.

It means conventional Japanese agriculture operates within a system that regulates how agricultural chemicals are used and how much residue may legally remain in food.

So the better question isn’t simply:

“Were pesticides used?”

It’s:

“Was the food produced within the applicable food-safety requirements?”

What Are Maximum Residue Limits?

A Maximum Residue Limit, or MRL, is the maximum concentration of a particular agricultural chemical residue legally permitted in or on a food.

Different chemicals and foods can have different MRLs.

Japan’s Positive List System prohibits the distribution of foods containing agricultural chemical residues above the applicable limits.

Where a specific MRL hasn’t been established, Japan generally uses its 0.01 ppm uniform limit, subject to the rules and exemptions within the system.

Australia regulates pesticide residues too.

Australian MRLs are established for agricultural and veterinary chemicals in food, and the APVMA undertakes dietary exposure assessments when setting them to ensure the proposed levels don’t pose an undue hazard to human health.

The important point is that the presence or use of a pesticide isn’t by itself a measure of whether a food is safe.

The particular chemical, amount of residue and applicable food-safety standard matter.

Why Are Pesticide Residues Discussed More With Matcha?

When you brew ordinary loose-leaf tea, you steep the leaves in water and then remove them.

Matcha is different.

The tea leaves are processed and ground into a very fine powder. When you whisk matcha into water or milk, you consume the powdered tea itself.

That’s one reason people interested in pesticide exposure often pay closer attention to how matcha was grown.

But consuming the whole tea leaf doesn’t mean a particular matcha necessarily contains unsafe pesticide residues.

If you need to know what residues are present in a particular sample, that requires appropriate laboratory testing.

Does Japanese Matcha Use Pesticides?

Some Japanese tea producers use agricultural chemicals permitted for conventional tea cultivation.

Others grow tea under certified organic standards.

Some producers may also follow their own cultivation practices within those systems.

There is enormous variation between farms and producers.

That’s why “Japanese matcha” and “organic matcha” don’t mean the same thing.

Japanese origin tells you where the matcha comes from.

Organic certification tells you that the tea has been produced according to a particular organic standard.

Neither tells you everything about the quality or flavour of the finished matcha.

Is Conventional Japanese Matcha Safe to Drink?

The fact that a Japanese matcha is conventionally grown shouldn’t automatically make you afraid of drinking it.

Conventional agriculture doesn’t mean “unregulated agriculture.”

Japan regulates pesticide residues in food, including through its MRL and Positive List framework.

Australia also regulates residues in food sold here.

At UJIHA, we stock both certified organic and conventionally grown Japanese matcha.

We don’t believe it’s accurate to tell customers that conventional Japanese matcha is inherently bad or unsafe simply because agricultural chemicals may have been used during cultivation.

If organic farming is important to you, choose organic.

If you prefer a conventionally grown matcha from a particular Japanese producer because you love its flavour, that’s a valid choice too.

What Is Organic Matcha?

Organic matcha is produced according to an organic certification standard.

For Japanese agricultural products, one certification you may encounter is JAS Organic.

Organic production places restrictions on the agricultural substances and farming practices that can be used.

But organic doesn’t simply mean:

“Nothing was ever used on the tea plant.”

That’s an important distinction.

If organic agriculture matters to you, look for recognised certification rather than relying on marketing words such as “natural,” “clean” or “pesticide-free.”

You can explore our Organic Matcha collection to see the certified organic Japanese matcha we currently stock.

Does Organic Matcha Mean Pesticide-Free?

Not necessarily.

Organic agriculture doesn’t mean that absolutely no crop-protection substances can ever be used.

Organic standards determine which substances and farming practices are permitted.

Organic certification also shouldn’t be treated as a laboratory guarantee that the finished matcha contains zero detectable pesticide residues.

Certification and residue testing answer different questions.

Organic certification: Was the tea produced according to the requirements of the organic standard?

Pesticide residue testing: What specified residues were detected in the particular sample that was tested?

Both can provide useful information, but they’re not interchangeable.

Is Organic Matcha Safer Than Non-Organic Matcha?

We wouldn’t automatically describe organic matcha as safer than conventionally grown matcha.

They’re different approaches to agriculture.

Certified organic matcha makes sense if organic farming standards are important to you.

Someone else may choose conventionally grown matcha from a Japanese producer they trust because they prefer its cultivar, flavour or style.

Both can produce excellent matcha.

That’s why at UJIHA we treat organic certification as useful information rather than a complete measure of quality or safety.

If you’re deciding between the two, read our guide to Organic Matcha vs Non-Organic Matcha.

Does Organic Matcha Taste Better?

Not automatically.

Organic certification describes how the tea was produced. It doesn’t tell you whether you’ll prefer the flavour.

Matcha taste can be influenced by:

• Cultivar
• Growing conditions
• Shading
• Harvest
• Processing
• Blending
• Freshness
• Storage
• Preparation
• Producer skill

We’ve tasted organic matcha we enjoy and conventionally grown matcha we enjoy.

The organic label matters if organic agriculture matters to you.

The flavour still has to stand on its own.

Can You Tell If Matcha Has Pesticides by Looking at It?

No.

You can’t determine pesticide residue levels from the colour, smell, texture or taste of matcha.

Bright green matcha isn’t proof that it’s pesticide-free.

Duller matcha isn’t proof that pesticides were used.

Likewise, terms such as “first harvest,” “ceremonial grade” or “premium” don’t tell you whether pesticides were used.

If you need actual residue information for a particular matcha, you need appropriate documentation or laboratory testing.

What Is Pesticide Residue Testing?

Laboratory pesticide residue testing analyses a sample for specified agricultural chemical residues.

This is different from organic certification.

A certification assesses compliance with a particular production standard.

A laboratory residue test examines a particular sample for the substances included in that test.

Testing also has limits.

A pesticide report doesn’t necessarily mean that every agricultural chemical in existence was tested. You need to look at what compounds were included, the analytical limits and the results.

That’s why a Certificate of Analysis or laboratory report should be read for what it actually tested rather than simply being treated as a “pesticide-free certificate.”

Can You Wash Pesticides Off Matcha Powder?

No.

Once tea has been processed and ground into matcha powder, you can’t practically wash it before drinking it.

Adding water doesn’t wash the matcha because you consume the water and powder together.

If pesticide residues are important to you, consider that when choosing your matcha rather than trying to remove residues during preparation.

How to Choose Matcha If You’re Concerned About Pesticides

Start with transparency.

Look for information about:

Producer: Who produced the tea?

Origin: Where does it come from?

Growing method: Is it certified organic or conventionally grown?

Certification: If it’s marketed as organic, what certification supports that claim?

Testing: Is relevant residue testing available if that’s important to you?

And remember that pesticide use is only one part of understanding a tea.

A conventional matcha isn’t automatically poor quality or unsafe.

An organic matcha isn’t automatically better tasting.

The more useful approach is to understand what you’re buying and choose according to what matters to you.

Organic vs Conventionally Grown Matcha

There isn’t one correct choice for every matcha drinker.

Choose certified organic matcha if organic farming standards are important to you.

Choose conventionally grown matcha if you’re comfortable with that growing method and prefer a particular producer, cultivar or flavour profile.

At UJIHA, we stock both.

Some of our own matcha is certified JAS organic. We also stock matcha from established Japanese tea producers using conventional cultivation.

We don’t think you should be scared away from excellent Japanese matcha simply because it isn’t certified organic.

We’d rather tell you what we know about the tea and let you make that decision yourself.

Frequently Asked Questions

So, Should You Buy Organic Matcha?

If certified organic agriculture is important to you, organic matcha makes sense.

But you don’t need to assume that conventional Japanese matcha is something you should avoid.

Japan has regulations controlling agricultural chemical residues in food, and conventional Japanese tea can produce exceptional matcha.

Organic and conventional tell you something about how the tea was grown.

They don’t tell you everything about how it will taste or whether you’ll enjoy it.

Look at the tea as a whole.

Who produced it? Where did it come from? How was it grown? What information is available? What does it taste like?

At UJIHA, that’s why we stock both organic and conventionally grown Japanese matcha.

We give you the information about the tea. You decide what matters to you.
