How long do you cold smoke your bacon?
It depends on the wood I'm using. When using alder and fruit woods I smoke longer. Any heavy woods, I smoke for a shorter period.
It's a matter of taste, everyone is different. I start checking the bacon after 6 hours no matter what wood I'm burning. Slice and fry a piece...keeping in mind it will be stronger after wrapping and resting.
Some times 6 hours is enough of a cold smoke (under 85F) for me, other times it takes 17+ hours.
Good luck with yours!
