In traditional Swiss cheesemaking, what gas do bacteria release during aging to create the cheese's characteristic holes?
Answer
Carbon dioxide
Bacteria such as Propionibacterium freudenreichii produce carbon dioxide as a metabolic byproduct during aging, and pockets of this gas form the holes, or 'eyes,' seen in traditional Swiss cheeses like Emmental.
💡 Did you know?
Swiss cheese holes form from bacteria releasing carbon dioxide gas during aging, yet most Swiss cheese sold globally contains fewer holes due to industrial production methods.
