Yep; the Huel matcha is pretty good value: elsewhere they’ve given caffeine stats which suggest it’s maybe around 50% matcha (with sweetener etc. making up the rest). The sweetener does make U/U+Huel matcha a lot more palatable than U/U+real matcha. I’ve recently been using real matcha and a ⅓ vanilla, ⅔ U/U Huel mix; it’s bland, but pleasant enough.
Re: matcha itself, people make a lot of noise about ceremonial vs culinary matcha, the former being far more expensive. I’ve yet to sit down and try to compare the two; have a vague suspicion my palate won’t be refined enough to tell the difference. I’ve found Super Foodies’ matcha, at around £25/250g, to be easy to find in shops and pretty good value. £10/100g is common enough in the UK; posh stuff can be five times more expensive, and there are people on eBay who sell direct from China for five times less…
