US-05 is a floating cake OK to whack it to make it drop?

[Fil]

I think the subject line says it all. :)

my current brew underway is 6 days in and at 1014-1016
ripe for transfering into 2ndary to clear. however with the yeast sitting as a 1cm pancake on top of the brew, it will be quite a lot of gunk going into 2ndary so i want to give the FV a whack to shock the cake into falling?

any problems doing that?

Usually the us-05 is a nice compact sediment base easy to pour cleanly out the side tap off the top of.

Why not just leave it for a few days longer

Cheer Tony, do you mean that it will drop itself in a few more days?

cos if i drain it with the floating cake, the thing will break up and will drop on the loose trub sediment kicking it all up.. like a thunderbirds under water explosion..

i want to give it a whack now so in a few days it will have all resettled ready for racking off..

going from what i can see thru the transluscent 4" neck FV its a 1cm thick cake thats welded itself to the FV wall,
the only sediment appears to be the break and trub that dropped in the first few hours of sitting. the gravity tells me its fermenting but i would have expected it to have done more after 6 days at 18-19C but if the yeast is lifting itself out of its food source???

ive just not had this yeast behave like this before?

its just the cap of the yeast mate leave it be and itll settle out then rack :thumb:

It will drop of its own accord eventually. The trouble is that it can take longer than it should if like you say it welds itself to the FV.

I have had this happen several times and have just run a santitised knife around the inside of the FV wall (being careful not to scratch the FV) when I want to speed the process up.

Wel i just gave the fv a little punch n watched it tumble down n crash into the trub... if not tomorrow I can transfer it on tuesday evening :)

I normally leave it 2 weeks beofre bottling.

That way I've never found the need to rack to a secondary.

It's almost clear then with most brews.
