Krausen kollar

[Diles]

Can the collar stay on for the whole duration of the fermentation. The video shows to remove after 3 days but surely this could increase the chance of wild yeast or contamination.

Yes.

I find it is only necessary when doing very high ABV brews or dark beers that will create a very tall Krausen.

All my lagers/ales I ferment without the Kollar.

Leave it on now but only need to use it for dark beers like dark ales and stouts ... from my experience they are the ones which create a heavy krausen but others may know more ...

.....and without an airlock, anyone?

No airlock is no problem. 

The fermenter is designed to work fine without an airlock.

I ferment without one too even though my fermenter can use one. I just put tape over the hole in the lid and back it off slightly to allow gas escape. Works fine.
