What is a good way of sanitizing a conical tank, while being able to say the beer is organic? Is iodine classed as organic?

Iodine is inorganic. And I wouldn't say that sanitizing a vessel with iodine, peracetic acid or whatever would nullify your saying a beer is organic, as you're not adding those sanitizers to the product. Others more versed in chemistry may very well chime in and prove my statements wrong"By man's sweat and God's love, beer came into the world" -- St. Arnold of Metz

Organic
Organic is a registered description. You have to join the club as it were. There are federal requirements, state requirements and some private organizations. You must adhere to the proper one in your area to use the organic description.
In Oklahoma the state has standards but also recognizes a couple of Organic associations.
If you don't want to join one of the clubs go for using natural on the label!Doug A Moller

Organic Sanitation
So I could heat my water in the HLT and fire it across to the conical. I would have to shut off one of the gylcol lines (but not both), and then toss the water back to the HLT - maybe push it out with CO2. A book I was reading a while ago suggested that very hot water in the conical could stress the tank, so I was hesitating on that method.

sanitizing
Our final step in sanitizing our conicles, and all of our vessels, is a hot solution of sodium hypochlorite followed by minimum 180 degree water (burns off residual sanitizer as well as santizes "by heat"). Obviously the chill loop is shut off and we push the final rinse out with nitrogen and allow the tank to cool under pressure and remains sealed until knock-out or transfer. This has not shown signs of stress on our tanks, and has been our process for 17 years.
Hope this helps,
Steve

Are your tanks made of stainless ? I assume so. Have you checked them for corrosion recently ?. If not, I suggest you do so, at the first available opportunity. You are likely to find little holes in the stainless where the chlorine has chewed its way in. You may even have the start of cracks developing best checked by use of a penetrating dye, possibly a specialist job. Hypo is best used at pH 11 +, in other words in a fairly strong caustic solution. At high temperatures, especially at low pH, the chlorine gets very agressive and chews up the chromium dioxide, the stuff that makes it stainless, allowing the iron portion of the steel to be oxidised
If your tanks are epoxy lined (unlikely but not unknown) then this is also likely to be damaged
Check them NOW, and use a different sterilant regimedick

organic sanitizing
The following is from the Nevada Dept of Agriculture handbook
which is accredited by the USDA.. We will use this for our, made with
"Organic" seasonal beer.
Check local Ag department handbooks to cross reference.
These are substances allowed as ingredients to disinfect
and sanitize food contact surfaces. Residual chlorine levels
in the water shall not exceed maximum residual disinfectant
limit under the safe water drinking act:
Sodium Hypochlorite, Hydrogen Peroxide, Chlorine Dioxide,
Phosphoric Acid, Potassium Carbonate.
If you need expert advice I would contact Brett Cooperrider
@ Ukiah Brewing in Ukiah California they are a 100% organic
pub and brewery I am sure he can supply some insight into your
organic questions.
good luck and send some samples

Our brewery is also certified organic.
Since the advent of the National Organic Program several years ago, you cannot make any organic claim to a product without having it certified. There are 3 levels of certification, 100% Organic, Organic (>95% organic ingredients) and Made With Organic Ingredients (at least 70% organic ingredients). Each level of certification does address some "processing aids" differently.
In regards to 100% Organic and Organic products, my understanding is that you can use almost any chemical sanitizer you choose, however, all except chlorine dioxide must be followed by a final potable water rinse. If you use chlorine dioxide in a no-rinse situation, then you must test the level of chlorine present on the surface of the equipment prior to contact with organic product. I believe there is currently an attempt (by some processors) to change the NOP standards to allow the use of peroxyacetic acid as an organic approved no-rinse sanitizer. When in doubt there is always lots of 180F water......Hope that helps!
