Fighting off a brewery infection

[hedgehogbrew]

The last couple of batches I have made have turned up sour. I have taken the following steps to eliminate this from any further batches:

Replaced my Star-San solution. I had been using the wonderfully high alkaline tap water of MN to make a cloudy solution. I purchased RO water to make the last batch of solution.

Replaced my bottling bucket and spigot.

I will replace my tubing before using it again also.

Should I replace my auto-siphon also?

Is there anything else I should do to stop this from happening again?

I would replace any plastic/rubber parts and really think about your process. Are you exposing you wort to air post boil or any other source of possible contamination?

Bleach/water is always a good weapon. Just rinse VERY well.

Take the valve out of your bottling bucket and soak it well.

OOPS, you said that already.

I had a few sour batches mixed between good ones. Never did figure out what was wrong.

I had the same issue a while back.i threw away any plastic . Soaked everything in bleach solution overnight, and changed the sanitizer. I was using idophor , but changed to star San. I change it up every couple of weeks just to make sure they don't get used to star San..long believe it but I am paranoid.

I also replace all my tubing quite freq now. It's somewhat cheap and not worth the hassle. I also went to a pot with a valve on it...only thing touching beer after it cools is the tubing , from pot to fermentor, fermentor and oxygen wand.
