I think cheese paper will make the cheese breath and will make the cheese form a rind. Using foil or air tight package, you'll deprive the blue mold with oxygen. This in turn will give the blue cheese a different flavor profile. Here's a quote from faribaultdairy
"In order to create the “complex, complicated yet delightfully intimate”™ flavor of Amablu® the cheese are carefully ripened in three distinct phases. The first phase is the initial ripening which takes place in the Salting Room. During this phase the P. rocquefortii becomes active and spreads throughout the cheese as colorless mycelia – the vegetative stage.
The second phase of ripening occurs in the Cure Cave. During this phase the blue cheese wheels are placed in special food grade plastic crates that allow the air to circulate freely around and through the cheese (the cheese wheels are “punched” with special stainless steel needles to provide openings to the interior of the cheese). The environment in the Cure Cave is ideal for promoting the growth of the blue veining. The Cure Cave has the delightfully fresh fragrance of an earthy garden in spring.
As the veining grows the P. rocuqefortii mature and develop fruiting bodies (sporocysts). It is the fruiting bodies that give blue cheese its characteristic blue green veining.
After ripening to the desired degree the cheese are placed in special hygienic pouches, sealed and moved to the Ageing Cave. During this phase the P. rocuefortii is deprived of oxygen and “goes to sleep”. Flavor development slowly continues as complex interactions occur between the starter culture bacteria derivatives and the mold metabolites. (See Frank Kosikowski’s classic “Cheese and Fermented Milk Foods” for a thorough account of the processes – and some pictures of our caves!)
The sleeping mold slowly loses its color in the absence of oxygen, going from blue – green to green to yellow. Amablu “St. Pete’s Select” is cave aged over 100 days. So, if your wheel of St. Pete’s has yellowish veining it’s simply assuring you that it is well aged! Allow the cheese to “breathe” at room temperature for 30 minutes and watch the blue green color magically restore as the P. roquefortii awakens."
