You know, there's a product that (IMHO) none of the cheesemaking retailers carry right now.
I'm fairly certain that spruce boards to age cheese on are not in anyone's inventory. When I went looking, it was difficult to even find spruce lumber local to where I live. I had to travel up to Seattle to find mine. Other folks may want to put spruce ripening boards to work in their process but don't have a clue where to get the boards. If they were fortunate enough to locate a source for the spruce, then there's the cutting to size and finishing. I was lucky that my Dad has the woodworking shop to complete my boards. I think if someone offered boards in a couple sizes that would fit into typical ripening boxes, they would fill a cheesemaking niche.
