Default Spontaneous Fermentation First Attempt

After reading through wild brews several times, studying the madfermentationists blog, and getting inspiration from others on this site who have tried a 100% spontaneous fermentation I went for it. I brewed a basic lambic recipe on 10/13/2013 let is sit with the lid cracked over night and today there's a pretty substantial krausen on it.

The first pic is where I had it sitting exposed over night. The next 3 are a timeline of it's krausen through today (pics were taken at 7am, 9am, and 9pm)

Does anyone have any experience with spontaneous fermentation? Any tips or words of wisdom as to what's in the beers future?

my understanding is that it's a crap shoot: you might get something awesome or you might get something awful. all depends on what critters got in there.

That has been my experience. I decided to make a starter, and based on the starter whether to ramp it up or not. I'd hate to waste 5 gal when I can only waste a liter.

yeah that seems to be the consensus. I heard a lot of people say that it can often be a pretty clean fermentation. I'll wait a few weeks and pull a sample to see what kind of a start it's off to. It filled up all the headspace in the carboy and blew off a little through the airlock. It has since dropped down and I can't see any visible activity.

Let it ride. It may or may not have any funk, but provided it has that good beer brewing smell and no rotting garbage smell it will be drinkable. The nice thing is no matter what strain of good yeast grows it will be in 'style'

I've had some success gathering ambient yeast. Best advice is to wait until air outside feels, tastes, smells "sweet". I know it sounds kind of zen, but we all know not to harvest ambient yeast in summer for all the crap that's living in the air and inversely not the in the dead of winter because there is nothing living in te air. So there is a sweet spot between summer and winter and another between winter and summer. Basically what I do is brew a lot of beer during these times and set my BIAB grain bags outside overnight. there is always about 300-400ml that will continue to drip through the bags into a bowl just by waiting. The next day I put it into a starter flask and it always takes off. This is unhooked and unboiled but when it ferments it is enough of a sample to know if he yeast is "good" or not. When it is good I step it up to 2 gallons and then to 5. If it sucks then I dump it. Let your senses be your guide I say. I've gotten pretty good at sensing when a good tasting ponta nous fermentation will occur. For example in South Jersey where I live it is too early to attempt. Air still seems to have too much crap in it...

Best if luck!
