Hello Kevin
I actually haven’t seen this to be as cut and dry as your comment makes it seem. A lot depends on the vintage, of course. In line with this is how each vineyard, each section responds to a vintage. I’ve situations in each vintage where some premier crus are darker than the Grand Cru of the same vintage. This is with keeping all of my inputs unique year over year. Keep in mind that the classification is not some neat and tidy system. It relied on an amazing combination of factors, including price, market perception, historical considerations, politics as well as those actually attached to the vineyard and its terroir.
I disagree that darkness has anything to do with perceived quality.
As I have mentioned previously, Burgundy is about nuances both large and small as well as individuality. This is not the place to apply rigid rules. It simply has never worked here as it does elsewhere. As you move up the classification ladder, you may generally find an increasingly unique experience.
Bourgogne should taste of the region. Though certain terroir and lack of blending can provide an experience that is more representative of wines found in the surrounding lands classified as village. Generally, across much more vineyard land, you will find really strong similarities to each other.
Village will generally provide an experience that is more so related to the subject village. In this tier, you will find more distinction between neighbor lieux dits. And finding village wines with an actual lieu dit mentioned will potentially provide a more defined experience though it will still trend strongly toward the general focus of the village.
Those classed as Premier Cru vineyards will generally have a significant jump in diversity of expression. In theory, a Premier Cru and its neighbor will have strong terroir differences between them with a slant toward the general village qualities.
Grand Cru sites are not the grandest in the sense that they are the largest in stature. They are the peaks of mountains only in the sense that they are so separate from each other, completely unique from the next. These are the vineyards that should have the highest probability of providing the most singular of experiences.
An interesting way to think of the wines of Burgundy is to imagine each as a sphere-like shape. Each one has different textures, colors, and other subtleties that the other may not. There is no right or wrong color, shape or texture, nor one that that is best or worst. Over time, the most celebrated wines have been those that have been known to have a voice that is consistently unique, not the one that is the loudest or deepest.
Cheers
