I seasonally cold smoke various cheeses in my trusty old Weber kettle. Starting outside air temperature shouldn't be over the mid forties and kettle temp must stay under ninety degrees to avoid a possible "melt down" for a two hour cold smoke so I typically start around 5:00 a.m. I mix up a blend of fruit pellets, 75% apple and 25% cherry and load them into an A-MAZE-N stainless smoke tube which is the only source of heat. Load the Weber with cheese and smoke tube, put the lid on tight with the bottom vent wide open and the top vent adjusted accordingly.
The hardest part of this very simple procedure is allowing the vacuum packed smoked cheese to rest and develop in the refrigerator for at least two weeks before opening/tasting. I still have enough from mid April to last until my next smoke this upcoming late fall.
The last photo (not mine) is from another forum and shows what happens when you don't read the instructions that come with the A-MAZE-N smoke tube. Quoted from page 6: "After allowing your pellets to burn for 10 minutes and they are burning well, SOFTLY BLOW THE FLAME OUT." He somehow missed that step and wound up with a pan of overheated fondue. BTW, pans are never used when smoking cheese but in his case, saved a lot of serious cleanup.
