There were 4 samples, each randomly taken from one of the milks.

My comments on the 4 samples:

1. pura, thick?, not so cold B+, maybe A- if colder
2. thinner, colder, pura
3. different, not clear taste, colder, not sure which this is, maybe pauls
4. thick but clear, this is the unhomoginised

What they actually were:

1. Pura Full Cream
2. Pura Full Cream
3. Pura Full Cream
4. Pauls Organic

I correctly identified 3/4 samples. The one I was incorrect (3) I said I was unsure about.

I probably should have rated all the samples, as well as noting their qualities.

Thanks to Nic H. for administering the blind taste test.
