What do you look for in a wine?
Is it power? Concentration? Complexity?
Does it matter if it is natural or not? Must it display a sense of place?
Is it simply deliciousness?
Do you want a wine that offers value for money?
Do you like sweet fruit? Oak? Tannic structure (in reds)? Are you an acid freak?
Do you have particular favourite regions? Perhaps those you have visited and which you have an emotional connection with?
Are you confident of your own taste, or do you like it to be endorsed by critic ratings?
