Dietary experiments

I decided to try and taste-test as many non-dairy milk varieties as possible. My reasons were:
1. Curiosity - to find out how they taste
2. Environmental-ish - everything I read seems to imply that cows are pretty energy-inefficient to produce and therefore beef and dairy come with a pretty high carbon footprint, so I figure if I can eat less dairy and still have yummy meals/drinks then that can only be a good thing
3. Health-ish - to see if less dairy suddenly gives me luxurious hair, glowing skin or magical vibrant energy

So, based on my research, the milks I can obtain in this area appear to be:
- soy milk
- rice milk
- oat milk
- almond milk
- hazelnut milk
- hemp milk

I'm starting with the cheap ones (~£1 per litre) and working through to the expensive ones (~£3 per litre). I'm approaching this experiment not from the angle, "Can I find something that tastes JUST LIKE MILK?" but rather from the point of view, "Does it taste nice and serve similar sorts of functions, in cooking, cereal and drinks?" Therefore, I won't be rating these milks entirely on whether they taste like milk, mostly on whether they have a nice flavour that works well in tea, coffee, cereal, hot chocolate, etc.

My inclination is to make a master post with reviews of all of them together, for my own future reference...

But I do like cheese. Far too much to part with it, I'm afraid.
