Whenever I need to attach a disconnect to my kegs to take a sample I first spray the disconnect and post down with star san. After I have taken a sample and removed the disconnect I spray the post down one more time.

This is pretty tedious. Is this over kill? Will my beer survive to live another glorious tasty day if I skip this practice?

It's not a bad idea. When flowing, the post is pushed down, then liquid covers the whole head of the post. If that head was previously exposed to the world, and/or has dried-up beer on it from previous use, then that can get into your serving lines, glass, growler, bottles, &c.

If you have a spray bottle of star-san at the ready, it shouldn't be that tedious to do.

Hmm, do you think it could contaminate the contents of the keg? –  fthinker Jul 27 at 18:23

Are you asking if the star-San can contaminate? No. As I understand it, in the presence of massive amounts of organic material it quickly loses effectiveness. –  uSlackr Jul 29 at 12:27
    
@fthinker, your beer-out should not infect the beer in the keg, but your gas-in might. Use the spray bottle as recommended. Not only does it clean, but you have a bit of lubrication for get the connectors on more easily. –  Atron Seige Aug 4 at 14:28

Short answer, yes you should. Longer answer, I often don't and haven't had any problems. Like many things in brewing, there's best practice and then there's what you can get away with.

Thanks. I've given the answer to jsled as his answer was a little more detailed, but you really deserve it as well. –  fthinker Jul 27 at 18:23
    
Keep in mind the risk is generally low in homebrewing. Contaminating a $50 batch is tragic but not back breaking. In a brewery, the downside, while still tragic is much more significant financially. –  uSlackr Jul 29 at 12:30
