Well I now have done two non sour beers all the way through bottling, with my equipment that has been in contact with Brett and Lacto. Non of these two beers show any sign of an infection or any thing else out of the ordinary. The last stout, was even in the same bucket that I did my Berliner Weisser in. I did not even switch out racking tubing on these beers. The only thing I did different was all equipment got a soak in bleach over night, and a good rinsing after use.
So IMO with good sanitation practices their is no reason to be scared of using these bugs/wild yeast. To further the experiment my last beer I bottled I only used star san, to see if it kills everything. (Which I believe it will). Guess I will find out in a few months.
Maybe im on borrowed time, but for now I will stick to only one set of equipment.
So in ending don't be scared of the wild brews.
