Love the product, hate ordering it at £2 more per bottle than it's sold in supermarkets, plus postage.
If it wasn't so expensive I could happily go through a bottle a day. It's not too sweet, which is a problem with most mocha flavoured products, which seem to confuse cocoa with chocolate syrup.
It tastes great with cows milk, or oat milk. I feel a black mocha is weird, so have no idea how this is when mixed with water.
