I have a batch of wort for a dark lager split into a 16L cube and a 6L cube. I also have one packet of dry lager yeast. The normal process here would be to get the yeast onto the YeastForge and make a 3L starter, then combine contents of both cubes in the fermenter, pitch the starter and blast it with O2 for 90 seconds or so.
I'm interested in what is likely to go wrong (if anything) if I was going to get the 6L cube into the fermenter, pitch the packet of dry yeast, blast it with O2 for 45 seconds and let it ferment. Then, when it looks like fermentation activity is just past it's peak, add the remaining 16L and blast with O2 for another 45-60 seconds.
The first thing that springs to mind is that, I'm effectively oxidising the first 6L of partially fermented beer and thus contaminating the entire batch with oxidised beer. Is that how it works or am I worrying too much and this is a reasonable shortcut?
