Hello all - I just started DIY'ing and am very interested in extracting some tobacco - towards the end of my time smoking I decided to try a pipe and fell in love with Mississippi River from the Seattle Pipe Club. I'm sure there are some casings/toppings on this tobacco, as is the case with most pipe tobaccos, and I think I've seen others ask about the use of casings on specific blends mentioned in threads here. Should I stay away from pipe blends with casings? Has anyone tried extracting some Mississippi River? I'm just not sure what the significance of these casings may be other than maybe gunking up coils? Thanks!
