Peracetic rinse

[Brewberosa]

Using a moravek bottling line with a peracetic pre rinse, as per manufactures recommendations. Also know other breweries with the same.

I am wondering what, if anything is served by this. Peracetic acid is all about contact time so I am wondering what the few seconds contact will achieve.

Why would a sterile water pre rinse not be appropriate?

PAA is an oxidizer, so a lot of people do not use that for sanitizing there bottles. I know that UV treated water is often times used as a rinse.

Absolutely, but the manufactures recommend it. Maybe they know brewers understand paa so its something we have heard of so they recommend it.

Not sure why though

I suspect the PAA is to sanitize the water, not the bottle. At the very low concentrations we use, and the very small residual of water most rinsers leave, I can't see worrying about it. We use PAA to treat our fobber water, and have never detected a difference between bottles which were fobbed and those that weren't.

A micro-filtration system should get your water clean enough for rinse.

I Agree, which is why I asked it was necessary. Thanks.
