red wine/brown hair

i don't know why but yesterday i really fancied a glass of red wine so after work and swimming i popped into our local 'clear skin' and purchased a reasonably priced bottle of red, buying this particular bottle was the fact it described the taste as: 'has chocolatey undertones'....why does this always suck me in, it was nice but no chocolatey undertones were tasted. i remember a white wine i bought a few months ago said 'tastes of anzac biscutes' i am always so disappointed.
