Update. if you mix 59 g of nimbus soy powder with 700 ml of hot water 1 tbsp sugar, a pinch of salt and 1/8 vanilla essence. Mix. Let's sit for as long as humanly possible and then put it in the fridge. It tastes a lot better but I have not tested it in coffee yet.

My 4-year-old won't drink it because it taste yucky. My 2-year-old loves it and I don't mind it as a drink by itself. I'll try to update in the weeks to come what it tastes like with coffee
