I'm such a N00B, I think I infected my batch
 

So I got to the last step where I needed to add the yeast in for my IPA. I had a small piece of paper towel that was soaked in Star San that was covering the hole in the lid. Well when I went to flip the lid over, the soaked towel dropped in the bucket and I panicked. I quickly took the spray bottle and sprayed my hand and arm, then reached in to get the paper towel. I ended up going down to the bottom (it ended up being buried in the foam on top, grrr). I think a part of my arm that was submerged in the wort may not have been hit with Star San. Needless to say I am expecting this to be infected. Really really frustrated considering this is my first batch :( I am using my bottling bucket as my primary, then using a glass carboy for my secondary.

How can I tell if it is infected? I am sure it is. I am such a freaking n00b. :(

No way to tell yet. Just let it go and see what you get. Don't let it worry you too much. If worse comes to worse your second batch will be even better. Most of the times we learn the most from our biggest mistakes/accidents.

Check out the sticky on the beginner thread about thinking you ruined your beer. Until it gets nasty of starts growing something funky, don't stress it. And even if it grows something funky, you may end up with an unintentional sour.

Edit: I see others beat me to it

Just because you think your beer is ruined certainly doesn't mean that it is. Never dump a beer unless it's absolutely hopeless, even if it is infected.

I would just let it go! Pitch the yeast and see how it turns out. Unless you've got some festering wound on your arm, I'm pretty sure it will be fine! :cross:

just call it arm pit ale

Haha good one... ;-)

Yeasts are really tough... Chances aren't too bad.... ;-)

Thank folks! Just a disappointment since it is my first real brew (I have a Mr. Beer for the past year as well). I was all excited about it, then I screwed up.

I have been reading this: http://www.homebrewtalk.com/f39/what-some-mistakes-you-made-where-your-beer-still-turned-out-great-96780/index18.html which gives me some glimmer of hope.

If I sample it in a week when I go to transfer to my secondary, would it taste bad if it were infected? Or would it take more time for it to fester while in the secondary to make it taste/smell bad?

Also, I read that if you get an infected batch, you should throw away anything plastic that touched it? (e.g. bottling bucket)

Relax, you're fine. Unless you're one of those people who only bathe once a week and your arm was really dirty...
I strive to properly sanitize everything, but when I make a mistake I think to myself, "How did home brewers sanitize EVERYTHING 100 years ago?" That usually makes me feel better. Read through the "Show me your infection" thread and know what to look for in a week.
