I keep all the cultures I can find on hand.
Flora Danica is probably my most used culture , along with MA 4001.
Also been using Lipase and Kazu a lot lately , kind of experimenting with them .
Kazu adds a nice nutty flavor to just about any kind of cheese , and Lipase tends to give a stronger more pungent flavor.
If you add lipase to Alp style cheeses for instance , they tend to be more pungent , like a parmesan , but with a smoother texture , I really like it.
You will lose the sweetness of the alp style cheese though , but to me , it's all about experimenting and coming up with something I like .
Other times , it's nice to stick with traditional recipes .
As for aging boards , pine is very traditional and easy to come by just about anywhere , Some Hardwoods may impart a flavor to the cheese , hard to say.
