I know this is an old thread, but I am hoping to get a reply anyway. I have a wine thief that I have used to sample a souring stout from a bourbon barrel that I have. No problem so far, as I keep my sour stuff separate from my clean stuff. However, somehow (whether in a drunken stupor or someone else did it unknowingly) it got stored in my clean bottling bucket with my clean bottling lines and what not. Do I need to replace everything yet again just in case or are the chances of infection just from being in the same general vicinity low? If I just use a strong bleach solution before normal sanitation processes will that probably take care of the issue?
