Do I need to add yeast to ensure fermentation of sugar in the bottle?

This is a general question. If I use a secondary to help clear up my wort, how do I know if I have enough yeasties to carbinate in the bottles? Do ever need to worry about this?

I read (somewhere?) that this may be something to worry about with lager brewing, but not ales. Thanks!

You don't have to worry, there will be plenty to carb the beer.

unless your beer has been in the fermenter for months and months and/or been close to freezing for a while. then no, you don't need to use yeast. actually i cold crash my beer as close to freezing as i can get for a several days and it still has enough yeast.

+1. Not unless your doing something pretty unusual will you have to add more yeast.
