I have decided to put a little bit of wort (without yeast in it) after brewing into a transparent bottle....just to do a forced fermentation test that I learnt from the book "Yeast" by Crish White and Jamil Z.
I have taken 2 photos of it....one after 1 day and another one after 2 days. The 1st one was completely clear.....but on day 2, a little bit of white foam appeared. Does this mean that there is wild yeast activity in there? Or is this something normal that happens to wort that is left at 68 F with no brewers yeast in it?
By the way....I have just checked the bottle again and there is a little bit of bubbling in it, meaning that something is eating the sugar in it. Then again......there is no brewers yeast in it. So...it is surely wild yeast infected.
Here is the day 2 image.
Should worry at all or in the main fermentor the brewers yeast will overpower any traces of wild yeast?
