We want you to feel confident that the Marukyu Koyamaen matcha you receive from us is authentic. This guide highlights a few key details to look for, based on information provided by Marukyu Koyamaen.

Inspect the Packaging

Pay close attention to the colour, material and finish of the packaging.

Marukyu Koyamaen notes that counterfeit packaging may differ in:

  • Colour

  • Packaging material

  • How the surface reflects light

The printing should also appear sharp, clear and high quality. Blurry text, poorly defined logos, unusual colours or noticeably different materials and finishes may be warning signs.

For a visual comparison, see Marukyu Koyamaen’s official counterfeit packaging example.

Check the Best-Before Date

Check the best-before date stamped on the back of the packaging.

Marukyu Koyamaen states that its tea products have a maximum best-before period of seven months from the date they are packed.

The date printing should look clean and clear. Marukyu Koyamaen has also identified counterfeit products with unusual date printing, including ink that could be easily wiped away.

Check the Matcha Itself

Once opened, look at the colour, aroma and taste of the matcha.

Marukyu Koyamaen has reported that counterfeit matcha may:

  • Appear more yellowish in colour

  • Have a weaker aroma

  • Taste more astringent

Keep in mind that age and storage can also affect the colour, aroma and flavour of matcha, so these characteristics are best considered together with the packaging and date printing.

Look at the Whole Picture

When checking your Marukyu Koyamaen matcha, consider the packaging colour and material, surface finish, printing quality, best-before date and the matcha itself together.

One difference alone does not necessarily mean a product is counterfeit, but several inconsistencies may be a reason to take a closer look.
