This is an old half burley and half Virginia blend. It does have a light casing of some sort, I cannot place a finger on what it is exactly. The casing is not overpowering so don't let that keep you from trying this blend. Now, let me start by saying I read alot of bad reviews on this blend else where and I was reluctant to try it for a long time. I finally broke down and bought a few pouches about a month ago. I find it to be a quiet satisfying blend over all. You taste the nuttiness of the burley and about a 1/4 of the way into the bowl you do start to pick up a little sweetness from the Virginians. As I said before the casing is light and gets milder throughout the bowl. In my opinion if you like Prince Albert, Carter hall, or any other burley blend I would recommend you try half and half. It is a nice break if you enjoy a number of primarily burley blends. I will warn you to smoke it slowly, if you puff to fast this blend will bite. It did in my experience, take it easy and you should enjoy this blend that has been around along time.
