I made my fina last night and after I was done it was the normal clear golden color, I look at it today and it has gotten coudy and there is a thin brownish layer floating on top. Whats the deal, is it still good?
If you filter back into the old vial, there will probably still be some of the residue you are trying to avoid. It will not be truly clean unless it is put into a new vial. But you can still use it the way it is.
