Unless someone has gone out and personally bought the item in question with their own funds and has no link/affiliation/freebies/or promises to the company a review isn't worth the paper (electronic or otherwise), it's written on.
Youtube is as good a place as any for honest reviews and these days most people's first port of call. Any that start with, company x sent me this to try or the description says 'disclaimer, this was a free sample sent by x for review' I click off and move elsewhere.
My reviews are items I purchase and can be brutally honest about as a consumer.
A written Web review is no guarantee of honest opinion either and it's easier to gloss over or not mention the item is a freebie for review which automatically invests you in giving a tempered response.
I.e.
'The taste of this isn't really my cup of tea but I could become accustomed to it'
Vs
'This tastes like a bolivian unicyclists jockstrap and I wouldn't pour it down the toilet for fear of offending it'
Also.
Taste is completely subjective, I know people who'd eat things and enjoy them that would make me gag and vice versa.
This alone makes taste reviews pointless with the sole exception of likening it to something known, i.e. This tastes exactly the same as the old fashioned rhubarb and custard sweets.
