Bit of an odd one to try and explain but when unable to first taste a wine before purchasing, what sorts of things will make you consider purchasing a wine?
For me when looking at wines online (no particular order) its:
Tasting note regarding flavour profile
Comment on any differentiation such as old vines or part barrel fermented
Reviews from non experts
Any mention of a food match
Price (in terms of VFM vs other wines also considering)
Overall vintage rating
I guess there is also the matter of how the bottle looks, I know the bottle itself won’t effect the taste but somehow I feel that having a quality bottle enhances the experience of drinking it. So I guess I should include a bottle shot into the mix .
