VA-Pers take in a huge number of blends with varying types of VA, varying proportions of perique, varying cuts, and varying methods of blending. Not to mention casings and toppings thrown in here and there. They have different strengths and tastes. Even amongst the same blender, different VA-Pers taste quite different. Take Dunhill for example, Elizabethan (ribbon cut) and DNR (pressed rolls cut into coins) have totally different smoking characteristics and taste profiles. Elizabethan is much lighter and less flavorful.
It gets even more complicated. Some have said DNR is the same as Escudo. They're made in the same factory by the same manufacturer, they look identical (allowing for natural differences in appearance from tin to tin of every blend), and the constituents are listed as the same. To me and many people, they do not taste alike however. DNR is sweeter, deeper and richer. That's why I smoke it. It seems to have just enough perique to add diversity and complexity to the taste (compared with Dunhill's straight VA flake) but not enough to make it spicy. I detest peppery-spicy, and can't stand a blend where the perique does that. Used judiciously, perique adds a tangy sweetness, but does not feel spicy-hot on the tongue.
