Hi Mermaid,
Apologies for the delayed response…
I am not entirely sure what the brown specks are, though I have seen them on many photos on the forum. I hope someone can enlighten us!
Talking of mould, I have been on holiday for a couple of weeks, and had left an unattended Lancashire style cheese aging in the cave! Photos will appear shortly, on the ‘Hard Cheddared’ page. Quite scary looking, but it brushed up well.
