[COHO] Oxygen tank

[Paul DeLeone]

Sorry I haven't been around and this is so late,but..............yes colder 
fluids hold more gas in relation to the liquid. But and I mean but, and hang 
with me, liquid can only absorb so much gas so it is not possible to "over 
oxy" your wort and cause delayed yeast action. will try and follow up on 
article(s) on this. Now the variables, ......temp,and don't forget the size 
of the stones being used. the smaller the bubble the easier it is to absorb. 
On pitch rates, how much volume was used. could be under pitching? to cold 
of wort.

Set up I have used has been the originator and the little red bottle from 
home depot or big r, now i use a bottle from norco welding supply.

steps that work for me.......
cool wort to pitching temps through wort chiller, use sanitize wand and 
stone and set in fermenter, turn gas on so bubbles just start to flow from 
stone. Let is sit why I working around the room, dumping brew pot, mash tun, 
pouring another beer.........................shake/swirl fermenter and add 
yeast shaking and gassing as i go. sometimes if I'm caught up with cleaning 
it may get 2-3 min, and sometimes (opps) has gotten 10 min. with no affect 
on has fast or slow lag times were. Yeast counts, temp of wort when ox'd and 
pitched has made the biggest difference. Most of my slow (extended lag time 
were from under pitching yeast or too cold, or being out of oxy and not 
shaking enough to aerate
