Small tank of oxygen for aeration?

[Normski]

Why not keep it simple. Just drop the wort into your Fv from your boiler.
Then thrash it for a few minutes with a plastic paddle to get a nice big frothy top.
Has worked well for me over the last 30 odd years.

So I’ve got a brand new drill I can dedicate purely to brewing however I cannot find a stainless steel paint mixer paddle that will fit in the narrow 75mm top of my plastic fermentasaurus fermenter.
I’ve seen galvanised ones that are the right size but I’ve heard that galvanised steel isn’t food safe and there’s a couple of threads that I’ve read with peaopke stating they would never use galvanised steel in any part of their brewery that makes contact with the wort.
Can anyone clear this up?

Have a look at wine degassers. Used on top of the wort they are very effective at beating it into a nice froth.

Why do anything in brewing? Why adjust water chemistry? Why use yeast nutrient? Why bother using liquid yeast when dry can just be sprinkled? Why even mash when you can buy malt extract?

If you want to make beer, none of these things are required.

But for me the hobby is about producing the best beer I can - mastering a craft - while still having fun. It's not for everyone, but I like to do all the little things to stack the deck in my favour of getting the best result possible.

Yeah I’ve seen the wine degassers, I’ve seen ones with metal prongs - do these prongs spring out when spun? and I’ve seen ones with plastic prongs that remind me of a garden strimmer. Is there any difference between these 2?

I would have thought thats the same for most brewers.

I strongly suspect that there are many ways to skin the proverbial cat! And it depends on the breed of cat you wish to skin (euphemism for beer variety being brewed).

As I said above - it's far more to do with the oxygen requirements of particular yeast strains. If you're using Yorkshire yeast they will be stressed by a single bubbling of air through a stone, whereas it's good enough for most yeast that a homebrewer will encounter.

The issue with zinc is more that although it's a very necessary nutrient for yeast, they don't like too much of it and the "Goldilocks" zone for zinc is quite tight, around 5ppm. So I imagine that's what people are nervous of.

These are a good as anything ime

I have looked at balloon whisks too but can’t figure out how I would attach it to my drill

This is my set up. Didn't cost much and the O2 has lasted three years so far.

Old school you don't need the drill. Whisk for 10 seconds. Done.

Richard how much did the set up cost u for the O2? The ones I was looking at were around £60 for oxygen then £30+ for regulator then extras like hoses connectors and the air stone too. All together it was looking around £100 which is why I though bollocks to that!

It was so long ago that I don't remember, but it was no where near that much.
Just did a search. The cylinder is £24 https://weldingsuperstore.co.uk/oxyturb ... efill.html

Interesting, well perhaps it’s something worth considering after all. Thanks allot

You will need a regulator (£36 https://www.welduk.com/product/regulato ... -cylinder/), an aeration stone (£8 for a basic stone, £17 for a wand) and some tubing at a minimum. Realistically you also want a flow meter (£10.26 https://www.ebay.co.uk/itm/265130660620), or you will run through your oxygen very quickly and need to spent another £25 before long.

You got it right first time..

.... bollocks to that!
