I have a couple of blocks of some 4 yo cheddar that i smoked 20 months ago in the fridge still in vac seal. The longer it sits the better. Most folks say 2 weeks but i smoke enough so that i can wait 2 months before i open a block.The more it sits the more the flavor mellows
I have done Cheese now three or four times and I always wait at least 1 month before I open any of it. I have recently been shredding the sharp Cheddar and putting it in Grits. Oh man is it good! My wife keeps asking me to make Smokey cheese grits (topped with caramelized onions and mushrooms).
