I use it all the time for Feta. It is a complete starter. this is what I think I know about it:-
Flora Danica comprises four bacteria types. Lactococcus lactis & Lactococcus cremoris. These two are your basic meso culture, same as in R704, MA 011-019 etc, all they do is make lactic acid. Then there is Lactococcus lactis subspecies Diacetylis and Lactococcus mesenteroides. These produce a substance known as Diacetyl which gives early flavour development, also a small amount of gas whioh keeps the texture open, but not so much as to create large bubbles. Hope this info is of interest. It is pretty much deduction on my part ( from the way it behaves ) as Chr. Hansen do not publish the recipe as far as I know. If anyone knows otherwise ( Niel you are a mine of info!) I would love to know.
