Even tho its not a specialty, id love you if you could get in some Rye Malt?? Im so keen to try a Roggenbier, and maybe even do a rye whiskey if I find someone with a still...
Also, just did a wikipedia read on peracetic acid, can it be used as a no rinse sanitser/cleaner?? Sounds like its pretty strong stuff, could be keen if I cant get rid of my pedio problem...
I can get it, as long as it is in the country. Maybe I'll have a play with it myself.
As for the peracetic acid - I need to check a few things (like whether I can ship it) - but it is a slightly 'better' sanitiser than iodophor from what I can tell and it oxidises to vinegar and water. It is no rinse.
I am actually happy with iodophor but wondered if anyone else was interested in going a step further. It's still a big maybe in my mind.
As for iodophor. I hope everyone remembers that as it loses colour it is also losing its sanitising effect. Get through it in a year if you can, and store cool and dark. Mine is a year old and has been stored in the cellat but I have noticed that it is becomg pale so I definitely need some more.

There's been a bit of vinegar / bleach no-rinse sanitiser discussion on AHB after the five star chemical guys (sorry, don't recall name) visit to the Aussie beer Congress that Barry went to (or whatever it was) Anyone tried it ?
(Jeez, my mind is mush this afternoon .. think I need a beer)
Yep - I use this method a lot. Basically bleach (sodium hypochlorite) is in equilibrium. Normal bleach is quite alkali and this means the solution is more hypochlorite ions and less hypochlorous acid. if you push the reaction to a pH of about 4-5 with acid you get more hypochlorous acid.
Hypochlorous acid is about 100 times more bacteriocidal than hypochlorite (i.e. normal bleach).
It's not the same as the peracetic acid solution above though as it still contains chlorine and isn't good to use on stainless and other metals but is a great alternative on plastic and glass - and use a lot less. You can use 1.5 to 2 mL bleach per litre. At this concentration it can be used no rinse but i am still paranoid about chlorophenols.
I've heard that hypochlorous acid is used in the bottling industry at these same conc's as a pre-bottling sanitiser but haven't come across a reference to this on the net.
