Top cropping yeast for the first time

Have just top cropped an Ale.BUT i have all the gear to culture so it was easy for me.
Last night canned some left over kettle runnings that i filtered then let it settle,diluted then reboiled.Then autoclaved in pressure cooker for 15min.Put 50ml of wort in preserving jar to put the top cropped yeast in till i transfer to a flask.100ml wort in 250 ml flask with foil on top and 700ml wort in a litre flask also foiled.


This morning sterised a 30ml ladle and funnel in pressure cooker san starred everything set up jar,flask etc.opened jar with lid resting on top,same for fermenter and pressure cooker.
Took deep breath scooped yeast from the middle of the foamy head and straight into jar with wort.Closed everything up and started to breath again.Re san starred after cleaning small spill
and transfered caught yeast and wort via funnel into waiting flask.Straight on to stir plate will give it 12 hours and step it up to the bigger flask if i think it is ready.


From what i have read you could also do this for SOME Lager/Pilsener strains if they produce a nice creamy Kraeusen on day 2 or 3.


Flame suit on as this is the first time top cropping,have tried to keep everything as aseptic as possible turned the heating off so less dust blowing around,autoclaved and flamed everything,san starred whole area including hands and forearms and tried not to touch or breath on anything that will come into contact will the yeast.
