Yeah obviously, wish I had known that earlier.
oxygenate a second time at around the 12 hr mark.Rocker1986 said:I pitched the yeast into my second batch using O2 yesterday arvo at about 4.15pm. It's an APA brew, OG at 1.051 in 26 litres, pitched with 1272 yeast from a starter. It's now sitting at between 18 and 18.3C or thereabouts. The cube was chilled down to about 20C in the brew fridge after I kegged the previous batch, and oxygen was injected for between 90 seconds and 2 minutes after tipping into the fermenter, and the yeast was then pitched cold into the wort. I checked it about 9.30 this morning and there was no sign of activity but another hour later and it looks like it's beginning to get going, with groups of small bubbles appearing on the surface.
Is this lag time of about 18/19 hours normal for this process and the yeast strain? I seem to remember reading that the lag time might be increased a bit with the added oxygen as the yeast will use it all up first before getting going, so I'm not worried about it and 18/19 hours isn't that long really, but just curious as to what other people have experienced. In the past before I began using O2, when I pitched ale yeast cold into the wort, I noticed lag times about half this time. Thoughts?
I'm not seeing this lag. My latest has just blown through the glad wrap at around 30 hours. So far quicker and more intense than in the past. Not enough O2? I gave it around 3 mins worth.Coldspace said:Yes rocker, it's lag increase due to more O2 been used up. It'll fire away hard in about 36 to 48 hrs.
All good...

IPA with OG of 1060. Yeast was Wyeast American Ale. At 48 hours it is still going nuts, SG down to 1038. So not ridiculous gravity drops but would be equal to the most vigorous ferment I have experienced.Brewnicorn said:What were you brewing out of interest?

Just a word of caution about cleaning crap from stainless steel - if you use a wire brush, use only one with stainless steel wire. Using a run-of-the-mill wire brush will scratch the surface and leave tiny fragments which will cause rust.Batz said:All stainless but has been stored several years so will need a wire brush up.
What regulator will I need to use this?Batz said:I have an unused 02 cylinder and flow meter four sale if anyone is interested. I bought it and then moved to a industrial refillable cylinder.

Hey mate did you still have any O2 regulators to get rid of? I'm weighing up going the tradeflame kit or a bunnings Coregas "trade and go" D size setup which would need a proper reg.Batz said:I have an unused 02 cylinder and flow meter four sale if anyone is interested.
