Geenz Posted June 8, 2019 Share Posted June 8, 2019 Is there any need to sterilise metal caps straight from a new pack ? Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 8, 2019 Share Posted June 8, 2019 Some would suggest so but I don't think it's worth bothering. The chances of something getting into the beer and ruining it from the inside of a brand new bottle cap are that tiny it's not worth worrying about. 1 Link to comment Share on other sites More sharing options...
RDT2 Posted June 9, 2019 Share Posted June 9, 2019 I’ve never sterilised mine I just make sure I handle the outside of the cap with clean hands and if I drop one I don’t use it. I also keep them in the packet till I use them and never had a problem. 1 Link to comment Share on other sites More sharing options...
karlos_1984 Posted June 9, 2019 Share Posted June 9, 2019 I put them in sanitiser before capping onto the bottle. 1 Link to comment Share on other sites More sharing options...
Shamus O'Sean Posted June 9, 2019 Share Posted June 9, 2019 When bottling I make up 1L of Starsan solution for using in my vinator (push bottles down on squirty uppie thingie). Before pouring the solution into the vinator, I drop my new caps into the Starsan then fish out and leave, tops down, on paper towel ready for capping. 1 1 Link to comment Share on other sites More sharing options...

On a side note the people that use sanitiser do your caps ever go rusty as I notice that when I have left bottles with caps in the esky have gone a little rusty or do they not because of what’s in starsan just interested? It obviously wouldn’t effect the beer as there is the plastic film/seal on the inside of the cap Edited June 9, 2019 by RDT2 1 Link to comment Share on other sites More sharing options...

Maybe I drink the bottles before it gets a chance to take hold. Edited June 9, 2019 by Shamus O'Sean 2 Link to comment Share on other sites More sharing options...

Cheers I probably answered my own question just waiting for a scientist to confirm that starsan maybe stops it from rusting because when I bought my stainless pot it said to treat it with something similar to starsan to stop corrosion etc. Link to comment Share on other sites More sharing options...

But, I have read or heard something similar about stainless steel too. Not sure it was sanitiser though (but it might have been). It sounded like something you could do with an old stainless pot, to take it back to non-stainless steel, then treat it to reactivate the stainless.

Otto Von Blotto Posted June 9, 2019 Share Posted June 9, 2019 Stainless steel has a chromium oxide layer on its surface, which protects the steel underneath and prevents it rusting. Nitric acid baths are usually used to create this layer in a process called passivation; once the metal is removed from the bath, the oxygen in the atmosphere helps form the layer. If the layer gets damaged by scouring or chlorine*, the process is done again to restore it and remove the rust. Oxalic acid is usually used in home situations like brewing equipment. The link below explains it more. Dipping crown seals in sanitiser may have a similar effect, since they're made of steel. *This is why bleach shouldn't be used to clean stainless. https://www.theruststore.com/What-is-stainless-steel-passivation-W85.aspx 3 Link to comment Share on other sites More sharing options...

karlos_1984 Posted June 9, 2019 Share Posted June 9, 2019 My caps sit in a bowl of sanitiser while I bottle and I've never had any rust. 1 Link to comment Share on other sites More sharing options...
