Difference Between Roquefort & Blue Cheese?

[Brian]

OK

I'm real new to moldy cheeses, and have only tried it once.

What is the difference between a Roquefort and a Bleu cheese, cheese?  Aren't they the same mold strain?

Brian, good question.

FWIW, my understanding here is that:

• The blue mold is from Penicillium roqueforti named after the caves around Roquefort on Soulzon River in S France where Roquefort Cheese was originally made.
• There are many strains of P. roqueforti, there are a few listed in the Product Data Sheets from manufacturers CHR Hansen & Danisco posted in our Library.
• Roquefort is made from sheep's milk whereas Blue Cheese are cow's milk based.
• Some blue cheese like Danablu, use both P. roqueforti and P. candidum, the white mold normally used in Camembert & Brie.

Anyone else please help here!
