Cold alone is not really an option, since yeast will not die but become dormant, and could be reactivated after heating a little.
There are a few ways to acheive this:
Pasteurization

How to avoid SCOBY in the Kombucha bottle? (second fermentation)
Not sure it's possible. SCOBY does what she wants. She likes to make floating pancakes. The best you might hope for is a high fill with a super narrow neck to keep the SCOBY as small as possible.

How to avoid SCOBY in the Kombucha bottle? (second fermentation)
You could heat treat / pasteurise the kombucha in the bottle, (once it's done carbonating).
Obviously this would kill off the beneficial bacteria, but it's those bacteria that make the floaty bits.
