If you’re trying to cut back on caffeine, you’ve probably started paying more attention to what’s in your cup.
Green tea, black tea, bubble tea, coffee, matcha… even some drinks labelled as “tea” can contain caffeine.
So what about buckwheat tea?
The short answer
No, buckwheat tea does not contain caffeine.
It’s naturally caffeine-free, which means you can enjoy it at any time of the day, including the evening.
Why is buckwheat tea caffeine-free?
Buckwheat tea isn’t made from tea leaves.
It’s made from roasted buckwheat kernels, a naturally gluten-free seed.
Because it doesn’t come from the Camellia sinensis plant, which is used to make green and black tea, it contains no caffeine at all.
How does the caffeine-content compare to other teas?
Here’s a simple way to look at it:
-
Buckwheat tea → 0 mg caffeine
-
Green tea → ~20–45 mg per cup
-
Black tea → ~40–70 mg per cup
-
Matcha → often higher than green tea
This is why buckwheat tea is often chosen as a caffeine-free alternative to green tea.
When is the best time to drink it?
Because it’s caffeine-free, buckwheat tea is incredibly versatile.
You can enjoy it:
-
in the evening, without affecting sleep (in fact, it is known to help with a more restful sleep)
-
after meals, as a gentle digestif (it also helps with digestion)
-
throughout the day as a simple, hydrating drink
In Japan, it’s often served alongside food or enjoyed as part of a calm daily routine.
Does caffeine-free mean less beneficial?
Not at all.
Buckwheat tea contains rutin, a natural antioxidant found in buckwheat.
While it works differently from the compounds in green tea, it still supports a balanced, nourishing routine.
