A few days ago I started extracting my first "real" honey crop - about 90 quarts when it was done.
After I'd already done a good bit of it I read on here that you shouldn't extract when it's rainy/humid which of course is exactly what I had done, but I figured that since my shop is very well air conditioned it would probably be alright.
Then I went to the local bee keepers meeting where I was told that one drop of water could start the fermentation process and spoil the whole lot. So the next day when I got back to work on my honey and uncovered everything that was in progress I thought I smelled that yeasty fermentation smell, so I investigated and sure enough I could clearly smell alchohol/fermentation in every single container I checked.
Man was I ever sick and sad. All that work and time for 2 1/2 years. All that money spent on equipment and sugar and bees.
When I told my wife and daughter they said it smelled fine - like honey. They were right, it was fine all along. But I swear It clearly smelled like fermenting beer to me - until after they convinced me that it didn't.
Paranoia will destroy ya.
