I'm reviving this thread because I am currently smoking my first bowl of the Edgeworth Cavendish Natural (Brown). Here's the pouch description:
Achieves a hearty, satisfying flavor from the natural taste of red Virginia, Maryland, lemon leaf, burley, and Oriental tobaccos, lightly flavored with genuine hickory smoke. The final blend is pressed into cakes for an ideal "marriage" of the tobaccos, then cut cavendish to make it smoke smoother and longer.
I have reviewed the Blue, Red, and Gold. Now, I just need to find some of the Green.
