@cawscenarth: Here’s the science part 🤓 Here we are piercing the cheese with needles 🪡 to create air channels. These channels allow oxygen to penetrate the cheese and promote the growth of the Penicillium mold, leading to the formation of the blue veins. The cheese is then aged in our controlled environment at Caws Cenarth, where we closely monitor the humidity and temperature. During this time, the mold continues to grow, and the cheese develops its wonderful flavour and texture. After several weeks our beautiful Perl Las is formed 💙 #PerlLas #OrganicCheese #MadeInWales #CawsCenarth #CheeseTok
