I have tried both and unsweetened and unflavoured (U/U) is very hardcore. The taste is very earthy and even with considerable flavour added I could not drink it. You could easily sweeten it. Huel use Sucralose which you can buy online.
I would only drink U/U flavoured, but I’ve met folks who drink it neat (not recommended). I didn’t find it hard to flavour though, in fact the sample flavour pack made 9 pretty decent shakes for me (I only make two-scoop shakes maybe that helped). Vanilla new and improved all the way though, it’s delicious and I don’t know why you’d want anything else
Old Vanilla (why is there old vanilla!). New Vanilla and UU.
For me, I can’t tell the difference between old and new, they are both quite sweet, but with a subtle flavour.
I got UU because to my brain, adding say maple to it should make it more maple and less maple and vanilla.
So it’s true, if you want a maple flavour, you get a better maple flavour with UU+ Maple.
You use a lot more flavour to get there.
UU on it’s own is as other have said really hard cord, so unless you have a reason to reset your taste buds, then I’d look at UU+ flavour.
I posted this in another thread about uu vs vanilla with the mint choc chip flavour.
So with vanilla,it’s more like mint choc chip ice cream. The choc part is nice, the mint a little artificial, but it’s very sweet! Even my teen daughter who is the chocolate queen, says it’s too sweet.
With the UU (<- omg I’m into huel acronyms now) it’s much more subtle, and I think more like an aero bar taste, so more like a darker choc mint.
Hope that helps, and its interesting to hear that others are doing to 1/2/ mix, as it’s something I’m tempted to do, but I’m going to ask in the feedback forum first!
I prefer Original Vanilla the most. I’m quite happy drinking that neat, or adding something else to it like organic cacao powder or those sachets of drinking powders which are 30p or so (Cadburys fudge, Maltersers or a supermarket’s own brand belgian choc or dark choc).
U/U is okay but needs something added to be enjoyable.
Wasn’t that keen on New Vanilla so won’t be buying that again.
