Changes

<blockquote>In fall of 2015, we had a hypothesis concerning Penicillium roqueforti and whether it would influence a beer with a distinctive Blue Cheese funkiness. Initially, we thought it may go through fermentation because it is part of the monophyletic group, ascomycetes (which includes saccharomyces cerevisiae). However, after further investigation we realized most likely any changes to the beer would be primarily enzymatic, followed by molecular conversions which may influence the sensory characteristics.

Regardless, after outlining our goal, we reviewed Blue Cheese production for approximately two months. After speaking to some cheese manufacturers, we realized that the P. Roqueforti is typically added during the curd forming stage. The organism is encapsulated inside the cheese form but won’t develop the distinctive veins unless a microaerophilic environment is achieved. Thus, in Blue Cheese production, the wheels are “needled”.

Needling is when the cheese maker takes a stainless steel rod and pokes small holes inside the wheel, allowing micro-oxygenation, and creating a microaerophilic environment. Over time, the veins begin to grow and the distinctive Blue Cheese characteristics develop.
