Yet another way in which homebrewing will go boldly where no brew has gone before.

Do some searches and you'll find out that this has been done, but not much.

Thanks for the interest folks! I've updated the second post to describe the side-by-side, and I'll keep things updated as I go.

Please do a control fermentation at the same time if you can.
Done and done. You know how much I like control (variables).

Definitely. I wrote the recipe for 100B cells because that's an easy number to scale. I really have no idea what a "proper" pitching rate for this kind of thing would be, but this time around I assumed it should be roughly near final cell count in a normal beer fermentation.

I am assuming sanitation is still an issue here... It would suck to make a batch that had a lacto infection. But, if you did, would the lactobacillus also not reproduce, the same as the yeast? I wonder if you could mix in a set amount of lacto or brett and end up with just the right amount of sour flavors. Also, Ill bet you could mix up two different yeasts and get consistent results, without one yeast eventually taking over.

I guess the Mr Malty website would have to add a yeast-ball option:

"For 5 gallons of 1.080 wort pitch 450 WLP001 Yeast-balls"

Buy the food-grade stuff; there are several different companies selling it. I just picked this one randomly. If anybody gets really into this, a $25 pound should last a long, long time.
