Do i need to add new yeast before bottle conditioning a lager?

[guitarist_713]

I'm planning on brewing a Marzen or Vienna Lager in anticipation of Oktoberfest, and having never brewed a lager I wondered if I would need to add new yeast to achieve carbonation when bottle conditioning
after having lagered just above freezing for 2 months.

No, but you can. If you do it probably will carbonate faster. I just sprinkle a few grams of a dry ale yeast into the bottling bucket.

I keg now, but I have made a half dozen or so bottle conditioned lagers. I lagered them for 4-8 weeks at around 37 degrees. I never once added more yeast and they all carbonated just fine in 2-4 weeks. Even though the beer may look crystal clear, there is still enough yeast hanging around to carbonate, but you may need to give it an extra week or 2 in the bottle
