I made an Expedition Stout Clone from a recipe on this site. Using the brewers friend (http://www.brewersfriend.com/yeast-pitch-rate-and-starter-calculator/) calculator, my O.G. target was 1.163 with an F.G. 1.050. Based on those numbers, I created a yeast starter with a calculator from the same site, and the cell count needed was ridiculous. There was a difference between mr. malty and brewersfriend.
Any way, I made a 2L starter with 2 Wyeast 1968 smack packs (39 days old) on a stir plate, that didn't stir all the time. I built up an additional 2L starter and pitched it on top and this time the stir plate worked just fine, so my estimate on a cell count is 600 billion. The beer ended up with an O.G. of 1.2 and according to the calculator I need anywhere from 686 B to 914 B depending on if I select probrewer .75 or probrewer 1.0 and 1.2 T cells if I chose probrewer 1.25 and I really don't know what that means.
So my question is would you add more yeast. Now I currently have my fermentor in a room that is around 70 degrees and am contemplating bring it to my basement which is probably around 60. I am leery of stressing out my yeast and getting flavors I don't want in a this beer.
