Geotrichum

[Jenellen]

Which geotrichum gives the most worm-like growth? Different sites give conflicting information.

Different strains have different characteristics, but it also depends on the base cheese - you need high moisture to create the brainy look.
"Geotrichum 17, 10 doses:  Geotrichum Candidum 17 is a mold-like strain.  Works great for combination with Penicillium Candidum; great for traditional lactic and bloomy cheeses. It is ideal for the creation of “brainy”/”wormy” looking rustic rinds. It has more texture than Geo 13 and Geo 15 yet has similar flavor strength. It has a similar white color, proteolytic activity, and optimal temperature to Geo 13 but it grows at a faster speed, more like the Geo 15."

Hello Jenellen,
I also have this question. The only freeze dried geo I can buy locally just produces a furry coat by itself, and works for me only to support P candidum.
Jenellen or anyone, did you find a strain that gives a "wormy" appearance in your experience eg with lactic cheeses? (An Australian source would be great as well.)
Cheers

You need the moisture content, then time. It takes a while for the cheese to go from smooth to brainy.
