When to oxygenate when you delay pitching the yeast?

I would oxygenate (pure O2) right before or after the pitch. Just because the process has the chance to introduce bacteria or wild yeast and it's best if the yeast is there to become dominate ...

Is **long** wort aeration a feasible alternative to using pure oxygen?

Yes, it definitely should be a feasible method. Yeast will rapidly (within a matter of hours) consume the oxygen that has been provided, at which point you may provide it more and it will happily ...

Possible to de-oxygenate and de-skunk a beer?

I think that's sort of like reversing a piece of wood in a fire being burnt. The beer has gone through chemical changes- it's nontrivial to reverse them. I'm not aware of any commercial or home-scale ...

Why is oxygen bad for mead?

You are confusing a couple of things. You want oxygen for a robust fermentation, no doubt about that. BUT, after the primary fermentation is done, you want to cut off the supply of oxygen otherwise ...

Can I use oxygen tablets or liquid oxygen to oxygenate my water for yeast fermentation in mead?

I wouldn't think of these things necessarily food safe. I wouldn't be adding something like this to my beer/mead without knowing what other substances are in it. You are overthinking the oxygenation/...

Is **long** wort aeration a feasible alternative to using pure oxygen?

The other solution is to pitch enough yeast to make aeration unneeded or at least less necessary. That's what I do.

Counter-pressure bottle filler and exposure to oxygen

My filler is a bit different, but it's the same principle. What I usually do is continue filling while I'm pulling out the tube to keep the foam at the top of the neck. I have my bottle sitting in a ...

Possible to de-oxygenate and de-skunk a beer?

Cardboard flavours are not the result of oxygenation but of oxidation. Oxygen has chemically bonded to chemical compounds in the beer and permanently changed them. While this process should reversible ...

Can I use oxygen tablets or liquid oxygen to oxygenate my water for yeast fermentation in mead?

The basics: just mix it up. I've made a few 5-gallon batches of mead, 30-some by this point. When mixing together my must at the start of a batch, I used to use just a big steel spoon to stir the ...

Brewing a Flanders Red Bruin/Historic C18 Porter?

Well, first of all, the grain bill is not one of red flanders. There's no place for chocolate malt, nor for flaked corn. 8 kg base malt is gonna give you too high OG for the style (assuming you're ...

Is **long** wort aeration a feasible alternative to using pure oxygen?

I think the aeration method outlined would work by making a lower but more prolonged level of O2 available - but it might be over elaborate or even unnecessary. The need for oxygen during ...
