I also use Cabot Seriously Sharp. I also have two smoke tubes with the pellets, but I much prefer a different method of cold smoking. The pellets & smoke tube tends to leave a metallic taste in my opinion. So I use wood chips in my home made contraption. I use a Campbells soup can with the top removed & a 1/2" hole near the bottom on a side. Insert a cheap Harbor Freight pencil soldering iron (about $5.00) & fill the can with alder or pecan or apple chips and plug'er in. Don't use anything harsh like hickory or mesquite. I place my cheese on the warming rack on my gas grill & rotate position after about a good hour of smoke. Can of chips generally last a good 2 hours.
Best yet!
