A month ago I brewed an all grain hefe. Took a hydrometer reading in a well sanitized hydrometer tube and recorded my FG. Wasn't being careful enough and accidentally left the sample in the hydrometer tube. When I found it 3 - 4 days later the gravity had dropped significantly. Looked like it had fermented in the chamber.
So when I brewed this weekend I deliberately left a sample in the well sanitized hydrometer tube. 3 days later it was clearly fermenting.
Is this caused by airborne wild yeast?
