I have made my first lager, and I am about to bottle. I brewed it December 18th, and racked the beer January 28th allowing for a Diacetyle rest. Since then it has been stored at about 36 degrees. I was wondering before I bottle, do I need a new batch of yeast to add for carbonation? I have been finding conflicting accounts on the web, and well AHA hasn't given me bad advice yet.
