A badge is not the same as a matching report.

Premium packaging can tell you a lot about a brand.

But it can’t tell you everything about the tea inside the tin.

Words such as premium, ceremonial, natural, Japanese and pure can describe a product. But they aren’t substitutes for product documentation.

That’s why we believe there is an important difference between a badge and a matching report.

What is a Certificate of Analysis?

A Certificate of Analysis, commonly called a COA, is a document associated with a particular product or batch that reports analytical test results.

Depending on the product and testing scope, a COA may contain information about specific microbiological, chemical or other quality parameters.

The important word is specific.

A useful document should allow you to understand what was tested and which product or batch the results relate to.

Why batch matching matters

Imagine a brand shows a laboratory report. That’s encouraging.

But then ask: does this report correspond to the batch being sold?

This is an important distinction.

A laboratory report for an old batch is not necessarily evidence about a new batch. Similarly, a report for a different product cannot automatically be applied to another product.

For a premium food product, traceability should connect product, batch, test and result.

What might be tested?

Depending on the product and applicable requirements, testing may include areas such as:

• Microbiological parameters — testing can help assess whether specified microorganisms are present within applicable limits.
• Heavy metals — tea and other agricultural products can be evaluated for certain heavy metals.
• Pesticide residues — testing can assess residues against applicable standards or regulatory limits.
• Product characteristics — other analytical parameters may also be relevant depending on the product, specification and market.

The exact testing programme should be appropriate to the product and legal requirements.

A COA doesn’t mean “perfect”

A laboratory report should not be interpreted as a guarantee that a product is universally “safe” in every possible sense.

It reports the parameters that were tested.

That’s why consumers should look at:

• Test date
• Batch or lot number
• Product name
• Laboratory identity
• Parameters tested
• Results
• Applicable limits or specifications

Why this matters for matcha

Matcha is an agricultural product. The tea plant grows in soil and is exposed to environmental conditions.

Quality therefore isn’t only about colour, taste and packaging. It also involves responsible sourcing, handling, storage and appropriate testing.

What Suko believes

We don’t want customers to choose Suko because we placed the biggest quality badge on the package.

We want them to choose us because we can explain what the product is and, where applicable, support our quality claims with appropriate documentation.

Our long-term goal is simple: make the journey behind the product more visible.

Origin. Batch. Testing. Product information. And the story of the tea itself.

Because premium shouldn’t simply be something printed on a label. Premium should be something you can investigate.
