I started culturing yeast from a La Fin Du Monde bottle about 3 days ago. I have since stepped it up to a 2L container about half full of wort. I have been very careful about sanitizing everything and the yeast are growing like crazy. Right now there is a fair amount of sediment at the bottom and always a bunch of krausen along the top of the wort.
My question is about the smell. I have read that a foul smell is bad, and it doesn't smell foul, but it does smell like a glass of La Fin Du Monde that has been mixed with some cider... definitely a far more cidery smell than that of a bottle conditioned beer.
Is this an "off" smell for culturing yeast, or is this on par? I have never done this before, so I just want to make sure that a slight to medium cidery smell was not an indication of a contaminated culture.
The wort mixture I am using is 1/2 cup Extra-light DME, to 1 quart of water, boiled for about 5 minutes.
