I contacted WYeast concerning the yeast count in their "wild" packs, this is the reply I received. I plan on stepping some Brett
up to a lager rate as per Chad's recommendations soon. I emailed Chad concerning this and a few other questions concerning all Brett
fermentations; he stated is is currently out of town and would fire off a reply soon.
For the Brett strains, the count is 75 billion viable cells total / pack. For the 5335 and 5733, the count is approximately 20 billion cells total/pack. The counts on the 3763 are proprietary. Please let me know if you have other questions.
