The matcha smoothie boom: what’s really in your drink?

In Stuttgart – as in cities around the world – matcha bars are popping up on nearly every corner, offering a colourful range of matcha smoothies, lattes, and even protein shakes. Once treasured and reserved for traditional Japanese tea ceremonies, matcha has fully entered the mainstream. And with that rise in popularity comes a wide variation in matcha quality and preparation methods.

But as anyone who follows the tea industry knows, Japan is struggling to keep up with the global demand for matcha. So how can there be so many matcha bars, and what kind of matcha is actually being used?

From ceremony to mass product

Matcha’s global popularity has skyrocketed. We love the fact that cafés and juice bars have embraced it, adding drinks like strawberry matcha lattes, iced matcha lattes and mango matcha smoothies to their menus. But while some places use high-quality ceremonial or culinary grade powder, others have taken shortcuts with sweetened mixes or lower-grade matcha.

Not all matcha is created equal

In traditional Japanese tea culture, matcha quality is everything. True matcha – ceremonial quality – is made from shade-grown tencha leaves, carefully processed and stone-ground into a fine, bright green powder. It’s smooth, subtly sweet, and full of umami.

But in the world of commercial drinks, what’s marketed as “matcha” can vary drastically. Here’s what you might actually be getting in your smoothie:

Culinary-grade matcha: A decent option for smoothies and baking. Slightly more bitter and less refined than ceremonial-grade, but still real matcha.

Matcha concentrate or syrup: Often found in cafés in Asia, this is a pre-mixed, sweetened extract stored in a squeeze bottle. It may contain artificial flavours, colourings, and only a trace amount of actual matcha powder.

Green tea-flavoured powders: Some drinks contain no real matcha at all, just green colouring and sugar.

How to tell if you are drinking good matcha in a smoothie or latte

When choosing a matcha smoothie keep the following in mind:

• Origin matters: Look for organic Japanese matcha, ideally from regions like Uji or Kagoshima.
• Look at the colour of the matcha being used: Good matcha is a vibrant, grassy green. Dull, brownish, or yellow-green tones are signs of poor quality or oxidation.
• Aroma test: How does the drink smell to you? A good matcha smoothie shouldn’t overpower the delicate aroma of the matcha — instead, all ingredients should harmonise to complement it.
• Taste test: If a smoothie needs a lot of syrup to taste good, the matcha quality may be lacking. Great matcha has a naturally balanced flavour that doesn’t need to be masked.
• Price: Unfortunately, price isn’t always a reliable guide. While a smoothie made with ceremonial-grade matcha could justify a price tag of €7 or more, many cafés in Stuttgart charge similar prices for drinks made with sweetened mixes or lower-grade powder. Ideally, a price of €7 should reflect the quality of the ingredients used.
• Ask the café: Don’t hesitate to ask what kind of matcha they use. If they are using good matcha they should be proud to show it.

Can you get good quality matcha that is not ceremonial quality?

Yes, absolutely. While stone-ground matcha remains the traditional gold standard, modern milling methods, like ceramic or ball mills, are now used by reputable Japanese producers to create high-quality matcha more efficiently.

These methods still preserve the delicate flavour, bright colour, and nutritional value of the tea leaf, making them perfect for everyday use in lattes, smoothies, or baking.If you’re looking for a reliable, everyday matcha, we recommend choosing a good-quality organic Japanese matcha that was grown in Japan, certified organic, has a fine powder, even though it’s not stone-ground.
