Different wort aeration kits

[eldertaco]

I'm currently using the bernzomatic based system, the one with a brass gaugeless regulator. It makes no reference to any standards on the reg but it does have oxygen stamped on it, along with some safety warnings about usage.

 

[MHB]

The gauges must have the Use NO Oil description or symbol to be sold in Europe under their standards.
In Australia the standards for fittings attached to disposable bottles are less well defined - the responsibility for ensuring that the equipment is safe and compliant with the demands of any standards fall on the importer/manufacturer.
So yes if a regulator is sold to fit a refillable bottle there must be the appropriate oil warnings as per the Australian standard.
No the Oil warnings aren't required for equipment for disposable bottles - however, the vendor is responsible for making sure that the equipment is safe, in this case that it has been tested to an acceptable standard for Oxygen equipment, the ISO mentioned would be a good one to choose. If you haven't done this testing and can prove it, if something bad happens you carry the can

Personally I would prefer to see the warning on the gauge, will be seeing Brewman on Friday for a couple of recipes, will ask that he get documentation from the supplier, first time I did this (back around 2010-2) I got about 20 pages in Italian.....

Remember that in the case of the fittings on disposable Oxygen bottles there are no AS requirements for any labelling, so Benzomatic are just fine as the importer is required to state safety and relevant compliance, and are responsible for the safety of what they sell.

I did a lot of checking and wore out my welcome with a couple of gas specialists at Work Cover, but at the time I started putting these together it was all a pretty much a mystery as at the idea of disposable bottles was quite new.

I have No concerns with the Benzomatic Regulator/Bottle combination, they have been around for a few years (over 150 I think), nor any other Oxygen Bottle/Regulator on the market where the parts are made/designed to work together.

Does anyone have any problems with this regulator?

You shouldn't run into any problems at all.
The only drawback is you can only attach them to the small Bromic or Bernzomatic cylinders which are quite small, about 40g of Oxygen I think.
The bigger cylinder setups are a bit more practical IMO.

Part of the reason I went with the tradeflame option was to get a cylinder with nearly 4 times the gas as a benzo one. Plus the ltr flow rate. More pratical than a small cyclinder without going full snot workshop setup. Especially for the amount I brew. Prob could have gone the Bunnings swap cyclinder option like the disposable option as well
That's all

Oxygenated up my first brews yest arvo,
Mashed a double batch of Irish red.
Tipped into 2 fermenters, bubbled 02 at 2.5 ltrs a min, for 1 minute each while gently stirring the wort.

Pitched a high krausen 2.5 ltr stepped up starter of Irish 1084 yeast that I got going from my freezer store earlier in week. 1.25 ltrs into each fermenter.

Checked today, and wow, really nice high even krausen in each fermenter at 19 c. Looking down through the glad wrap, the are identicle and deff are looking more healthy , quicker and that from my previous Irish reds I did with just starters and paint stirrer .

So far success I feel, can't wait to get into lagers this spring/summer.

I went the Brewman option, arrived in 3 days from Newcastle.

1st effort yesterday, had a no-chilled amber ale in stock, O2'd for 60 seconds, stirred in liquid yeast (1 day on stir plate) that had a burst of 02 and popped into ferment fridge at 5pm @18C

Back from tennis 8.30pm and krausen starting to form on top.

Check at 6:00am this morning on way to airport, at least an inch of krausen.....wow this really works.

Interested to see how long ferment takes as prior to 02, 10 days with US-05 was typical.

Brewman is in Newcastle, I wonder why it came from QLD :/

 

[Crusty]

I have no reservations about using my little setup & will do so until the oxygen eventually runs out.
I did however purchase a much larger setup consisting of a Cigweld oxygen regulator
And the Bunnings Coregas deal that is a $200.00 refundable deposit + $69.00 for the oxygen. A simple cylinder swap thereafter for $69.00. If you opt out, return the cylinder & get your $200.00 deposit back. It's a bit more expensive this way but there's no argument now about parts compatibility.

 

[Brewman_]

I Suspect Mall, meant arrived to QLD in three days.

They all ship out of Newcastle.

 

[Crusty]

Isn't Mall in Melbourne?
Anyway, he received it quickly so that's good service.

 

[Mall]

Melb yep, QLD, Newcastle doesn't matter, quick delivery = happy customer!!

 

[Brewman_]

Good either way!

I am not sure who is who on here all the time.

Just noticed you said 3%, sorry, I usually use peroxide at 30%. Just multiply volumes by 10 eg 0.6 ml per litre of wort, 12 ml for 20 litres.

I'd be interested to know how this goes: yes peroxide breaks down to oxygen and water but from experience when adding it to white grape juice, it does a lot of oxidation before it breaks down.

All I had on hand was an old bottle of 6% hydrogen peroxide. It's been kept in the dark and mostly under 25C, but the bottle was opened about 9 months ago and about 1/3 used. It's been shut since then. I've made the assumption that the concentration is still 6%.

I made a 1 litre starter wort, put it on a stirplate and let the temperature come up to 20C. I then added 0.3ml of 6% hydrogen peroxide at a rate of one drop every 30 seconds while the stirplate was going. Once that was complete I pitched in some yeast slury.

That was about 4 or 5 hours ago. I just checked the starter and it's looking very healthy.

Of course, this experiment does not prove anything, except that adding hydrogen peroxide at the rate suggested does not have a disastrous effect on the yeast. I guess the next step would be to do two starters, side-by-side and see what effect the peroxide has. I'll probably use hopped wort for that and will do a sensory evaluation too.

Back to my Irish red ales I O2 up and pitched 1084 last sat arvo as per earlier post above.

Nice thick krausens after 18 -24 hrs, moved along fast and healthy . Day 4 today and looks like their all finished up. 95%. I'll do a reading to confirm tomorrow or Friday when I get time. Then I'll be cc them at 0 degrees for 10 days before kegging.
Works a treat the O2.

Last red ales I did with 1084 after stirring up with paint stirrer still took solid 7 days with healthy starters then were left for another 5 days to finish the final 5% as the yeast lagged on slowly.

These batches look like done in 6 days max. Plus less chance of infections etc.

I'll be keen to do this on my up and coming summer lager season,

If your allgraining, temp control , starters etc, these 02 systems are like icing on the cake......

I've been ignoring it so many times but this was the straw that broke the camels back. It's O2, not 02. As in O for Oxygen, not 0 the number.

One little typo.... Got anything productive to add?

When typing fast on an iPad , the numbers 0 2 are on same page , so, **** it , just go 02 people lol

If that annoys you, I feel pity on you.

Used O many times, some reason went 0, prob had a few too many sarvo....or were just typing fast on iPad...

Back to proper discussions,

 

[Coldspace]

Got a couple of lagers planned for next weekend, nice big 3 ltr stepped up starters, 02, oops , I ment O2 , 90 secs, and then Bam.

Prob will use up the little oxy kit fast, will get onto the bunnings swap n go system, I'll go thirds with 2 mates, plenty of oxygen then.

Cheers

Actually yeah, and it's a bit 0T, but I was wondering why you need a 10 day CC?
