I’ve never had kukicha tea before – from what I gather it’s made from the stems and twigs of green tea, rather than the leaves.
The tea has quite a sweet flavour, though I’m not sure if this is due to the blueberry flavouring or the kukicha itself which is supposed to be sweeter than its leaf counterparts. The blueberry is fruity and natural-tasting, which I’m always in favour of. There’s also none of the bitterness or mouth-drying astringency that you get with many types of green teas; this is quite sweet and smooth. It doesn’t taste overly vegetale either, having more of a fuller, richer taste.
