I was;t sure what to expect as few reviews had real problem with taste. I mixed it in 500ml water, taste is ok, no need to worry. The taste is personal preference and I'm glad that I tried this blend and is fine by me.

Probably one of the worst-tasting proteins I have ever tried. The aftertaste is incredibly disgusting and metallic. Just do not buy this flavour

It mixes fine but tastes really unpleasant, not like caramel or coffee at all.

I have tried normal Whey chocolate (different brand) but trying this coffee caramel one I have to say I am struggling to even drink the first lot. Every time I sip it I feel like I am going to be sick. It smells horrible and it definitely doesn't taste very nice. I even tried adding a little flavoured juice but it hasn't helped I generally heave every time I take a sip hoping I will get used to it but I honestly don't think I will. Personally I would go for something different and have just ordered a chocolate normal diet whey so fingers crossed.

I haven't found anything it tastes better with yet.

I just tried this as it was on offer and was pleasantly surprised. The flavour is really nice (coffee caramel). It mixes really well, much less lumpy than impact whey protein but it does get very foamy so you have to let it settle for a couple of minutes before drinking. The powder itself is very fine so has a bit of tendency to end up everywhere if you’re not careful. I’ve used whey protein for years now but might convert to this if the price stays low enough.

Horrible taste and does not mix well or thicken. Very watery. Works better in yoghurt or overnite oats as it thickens a little when refrigerated. Would not buy again. Tastes very artificial compared to other vegan blends iv tried

To be honest, it's not the best vegan blend I've tried. Sickly taste and doesnt mix well. Very watery and tastes quite powdery. I wouldn't buy it again

Iv mixed it with Greek yogurt to make it easier to drink/eat

AVOID!! blend the contents of your bin and mix it with water. It will be similar, if not better than this.

I really liked the sound of this but there is absolutely no white chocolate flavour and it's completely overpowered by the cloying fake raspberry flavour that leaves a nasty taste in your mouth. I've tried mixing it with different things like water, oat milk and into porridge but there's no getting away from the taste
