I recently captured directly on to a plate, and selected 3 different colonies from that to grow up into starters. After a couple weeks of building them up to 1000ML, only one even had a good smell. I tasted them all, and the one tasted like a beer brewed with Notty, so I think my yeast was just in the air.
I'm using it anyway in a pale ale now, so we'll see how it goes. The rest tasted horrible!

I think I more intrigued by the ones that smell horrible at first...

I'm curious, I've been working on my 3rd and 4th generation juniper yeast, (top cropping, lagering, wheat, etc). At some point can I assume that there are no sour yeast/bacterium in it? I've not seen any evidence, with last count I've done 16 batches. If not, how can I be certain of this, outside of laboratory testing?

Edit: The reason I ask is that I'm contemplating sharing this yeast with "friends" for more help in testing, don't really want to infect anyone with something they don't want. I would think if I haven't had any infection, they wouldn't, but I know nothing of their sanitary practices, etc.

How long did you wait? Wild yeast can ferment very slow, and can be an indication that you have something truly "wild".

The 8 wild guys I have going tasted horrendous a month ago, and ferment very slow. Now they taste actually much better. Early smell and taste might not be a good indicator of how things turn out in the end, but I do not know when you tasted them.

If you did 16 batches I would say you would be safe. If you have not had any problems with bacteria all those times, and your friends all of a sudden going to have some, the problem might be on their end.

You cannot be certain what you have without doing laboratory testing, pouring plates, microscopy, plating etc. Also I do not know what laboratory testing really is, pouring plates and looking at colonies is quite basic for some, it is the same as changing oil in a car, for some people easy but for some it is hard.

You could have a nice consortium of organisms there which gives you the nice beer you like (different yeasts). If you try to isolate the single yeasts, you might end up with something different. But you might have a single yeast too. Hard to say.

Either way, tell them it is like an investment, there are some risks involved, albeit very small.

Does out side temperature matter? I live in the tropics, not the easiest place to brew. but would love to try this out.

Only a couple weeks... Maybe I should have let them sit longer. I'll make a point to do that next time.

final update to this "experiment":

got around to tapping the wild patersbier keg last weekend, and took a pic of one of the first glasses. the beer has a sticky, fluffy head, slight fruit in the aroma, and a taste that is slightly earthy and phenolic with a little fruit in the finish.

as per the earlier discussion re: control vessels and harvesting locations, my sample was harvested away from where I ferment and the wort I used was boiled in the collecting flask for 10 minutes, so I have doubts that any of my previous commercial strains contributed here. that, and the yeast cake was unique in both color (white) and texture (flaky), for what it's worth...
