Using Pure Oxygen

[SiHoltye]

Evening all. I've gone and plunged into this oxygen thing in as much as I believe I have what I need to add pure oxygen to my unfermented wort and I would like to achieve around 10ppm is it?

What is the calculation I need to consider using time flow rate wort quantity etc. Thanks in advance.

OOOOOOOOOOOO nice looking toys.... i cant answer your question, but am very interested to hear how it all works out
Have u got a spill tray ready to catch the overspill of kraussen i hope your rewarded with.. u can get a 50cm x 50cm x 10cm gravel tray from garden centres

Aw man don't say that I've found overpitching reduces krausen on top croppers, though the flavour suffers a turn to the blander so I've stopped for now.

Search for posts by gregorach - he seems to be the go to guy for O2... Post your findings back here as I m sure there are plenty of others who are interested!

My own experience with a 0.5 micron stone is set your flow meter to 1l a minute for 30-40 secs for 1040-1050 beers, high gravity 1100's need 90 secs at the same level, a further shot on high gravity beers only after 12 hours also helps,
You get quicker fermentation starts, remember only before you pitch yeast, our O2 will kill yeast.

Nice looking setup. Wher did you get that flow meter from?

Mercury welding in Horsham. Next door to King Beer as it happens.

Is the bottle from there too?

Is that for 5 gallon batches?

Here is some good math for how much and how long
