Infection, but not

[ben062479]

Hello All,
1st, Thanks for the great forum. I have been reading for months all the way from Extract to Partial to AG now.

2nd, I have done over 20 brews, last 12 have been AG. i am not making "great" beer, but I am getting better. I haven't missed a weekend of brewing in 9 weeks.

3rd, I managed to get my 1st infection (Slimy Pedio "ropiness"), but have brewed 2 more since without problems, so I am not too concerned. I was extremely tired and probably got sloppy. I reused the yeast cake with the infection prior to knowing that it was infected, I was taking this weeks stock of beer and remembered I had done this, but to my surprise no infection in batch 2. I did not sanitize the carboy from the 1st batch, just racked off and ran through plate chiller on top.
Any idea how this is possible?

Thanks again.

Are you bottling or kegging your beer?

I bottled 4 bottles for aging and kegged the rest. It was an English Ale w/ Wyeast Whitbread 14 days in Primary, 14 days in keg. Sanitation was good on keg and bottles, I am almost positive that it was infected in the primary.
