One thing I've noticed with VaPers is that different blends have very different tin notes. For example, Virginia Jazz and Boswell's Private Stock are two that I enjoy that have a very "barnyard" aroma while others like Bayou Morning ( which boasts a large amount of Perique) and Rouxgaroux have a much different tin note. I enjoy all these blends but this is something that I've been pondering. Is this due to different varieties of Perique used or age or what?
