I would have to say FOUR! Burley, Virginia, Haddos Delight and Latakia. Now, I have a pipe dedcated for the first 3 listed and the majority are for Lat blends. With the latakia, it really depends which pipe I feel like smoking. As far as how many open/jarred tobaccos I have, there are plenty. Just did a quick count, I have 28 jars of vairous sizes.
