Using two Saflager-23 Packets for Doppelbock?

[Jeffo]

I was buying ingredients for our Doppel at the LHBS and he suggested using two Saflager 23 packets. Two questions I have:

Should I use two or somewhere between one and two?
What happens if too much yeast is used?

We'll have 9 lbs. of LME, one lb. of DME and 2 1/2 lbs. of specialty grains that will be mashed for a five gallon batch. Fermentation will be at about 60dF. That's as cold as we can get it.

Thanks.

overpitching is hard to do. in my opinion, you should definitely pitch 2 packs in a lager. better safe than sorry - a stalled fermentation can be a nightmare.

60°F is pretty high...you're making more of a steam beer.

I'd go with two packs.

If we could somehow lower the temp how would that change the flavor? Or conversely how will the higher temp change it from what it should be? Thanks.
