Most experienced wine connoisseurs and tasters will tell you that the basic first steps in appreciating and experiencing a wine is through smell, taste, sight, and finish -- in retrospect I've often put more emphasis in smell over taste, and more recently tried to ignore the color of the wine all together to reduce any coloring bias.
Usually from the first glass poured a series of forms and colors emerges forming the framework of the representation to be painted. Along the way this can become finessed further or even change completely as I continue to taste a wine over the period of a night or the next two-to-three days as different aspects of the wine may become more prominent or fade away altering my impression entirely. This approach is quite subjective but may speak more to how we at any given time, on any given day, in any given mood experience wine throughout its life cycle. Luckily there have been few that have been so drastic as to go from something exciting to something bland and I'll do my best to note this in my reviews.
Simultaneously a wine develops a sort of 'gist' color, which is a color that generally identifies it allowing it to be placed on the color spectrum: this is the end goal, to create an interactive wine spectrum where, through a few search functions, any visitor can search those I've tasted and see how it's been described. The description also develops in tandem with the visuals and often ends up supporting and playing off the pictorial representation.
