The Patent states that it requires 1ppm to be effective and 1ppm of standardized 30% Hop Extract like Iso Alpha Acid extract is equal to 1 IBU .

If you put pressure into the keg then when the vacuum is created won't the co2 go into solution? Also, not sure about exposing the wort to air as it cools, even with a filter on....I would say just buy a couple of the US plastics containers. That's what I am planning on doing.

Yes you are right. I was thinking sanitation and forgetting about oxidation. I was trying use equipment I already have vs. buying stuff I don't have.

I can understand that --- If you have a way to oxygenate the wort before pitching yeast, absorbing CO2 probably wouldn't be a big deal.

The patent is talking about a beta acid containing extract made with a solvent.

Beta acids are not particularly soluble in wort which is why, despite the fact that isomerized beta acids are bitter, beta acids are completely ignored in most IBU estimations.

If you actuly read the patent the Extract which is the patent for the Barth Haas product Betastab does contain some Iso Alpha Acids but they use more beta's because they are not as bitter and remain below taste thresholds in the finished product.



Iso Alpha acids are actually more effective as a Antibacterial against gram positive bacteria and they work by disrupting the nutrient pathway at the cellular level so the bacteria starve this is more effective if the PH is raised also having a higher gravity/IBU wort at packaging helps and the customer can easily dilute the wort with some water when they brew .

http://www.lfl.bayern.de/ipz/hopfen/...poster1_01.pdf

If you added a mild food grade acid (phosphoric) to the wort and then added some sort of carbonate (potassium bicarbonate) to neutralize the acid when you brew you would pretty much eliminate any risk of any food borne pathogens because the increased PH enhances the Antibacterial properties of Hop Acids as well as acidifies the wort slightly , but I would only recommend that you add a Food grade acid if you where going to store your wort for months but most homebrewers are only going to be storing wort in cubes for a few days .

Reason: Added the PDF Link

Got my 6 gallon containers in from US Plastics today.



I have a ton of #2 bungs and several blowoff setups for #2 so I drilled 5/8" holes in the center of the lids rather than buying 11.5 bungs.

That and beer is to die for....

So are you all cubing yet... i live and breathe, testament to the fact that although i no-chill cubed 4-5 brews before pitching you can survive it.
I'm no scientist but i can say it works....

I no chilled another beer yesterday, actually I sold off my IC yeterday too!

I had a guest over from HBT for a brew session yesterday, who could not believe that I was not chilling my beer. So I pointed him at the tap on my kegerator where my No Chill Haus Ale was, he loved it. He mentioned how CLEAN it tasted... seriously, no chilling works.

I converted at least one person to brewing on an electric HERMS yesterday and possibly two people to no chill brewing.

Brew On!

Ah, OK. I follow aussiehomebrewer.com and the Aussie-isms are a bit difficult at times- though I must admit the question was tongue in cheek. The missus and I make kabobs ourselves, including homemaking the flatbread and yogurt. It’s not too difficult, really; especially compared to home-brewing beer.

Kudos to you and your countrymen for your spirit of adventure relating to home-brewing. I’ve adopted a modified Real Ale in a Cube system, learned from an Aussie, and it’s the greatest thing since sliced bread.

I shall try the no-chill method very soon.

Eschatz tried my no chill Haus Ale today... he seemed to like it just fine. My no chill SNPA clone is chugging away 24 hours after the boil!
