i cant seem to find alot of support on brewers having top-cropped lager strains. despite the fact that they are "bottom-fermenting", i still see alot of krausen. i wonder how much yeast is is it.

It seems to me that most of the krausen might just be CO2 bubbles on the surface. I'm sure there's yeast in there but maybe not as much as with certain ale strains. Have you tried top cropping lager yeast yet I have just started top cropping through a blow off tube with a bit of CO2 back pressure, but am looking for better systems.

havent tried but i was thinking about it. i've top cropped belgians and wlp-001 before but i would just ferment the first beer in a bucket so that i could scoop with a spoon. it killed me to open that bucket and i was paranoid that i had contaminated the batch each time that i've done it.
