Titel: Wort aeration methods
Bericht door: Wamser op 07-03-2016 16:44 u
Hello guys

I know the oxygen is very important for yeast growth and reproduction...
Yeast must grow and reproduce first, before actually fermenting the wort to make beer.
Commercial breweries typically shoot for 8 to 10 ppm dissolved oxygen in wort prior to fermentation

There are three approaches typically use to oxygenate wort; agitation, splashing and injection of either air or pure oxygen.

I use the agitation... but I will buy this:
Eagle Brewing BE510 Siphon Spray Wort Aerator

I think all methods are used here, everyone has their own preference or sometimes lack of choices due to setup or budget.
If you translate the forum you're bou d to find topics with pros and cons of pure oxygen vs filtered "plain air" and all the methods.
So I guess anything goes and try what works best for you.
Sharing your experiences is much appreciated though ;)

Well I mostly (read always) use the "slash" methode never had any problems, although now I'am hesitating before I  start with my Westvleteren 12 clone.

I've made 5 gallons off 'starter"beer OG 1040 pitched it with one WPL530 and it didn't go further then 74% thats not good enough

Same brew with the Forbidden fruit from Wyeast went all the way to 84%

I use a wine degasser on a drill.  https://www.google.be/url?sa=i&source=images&cd=&q=wine%20degasser&ved=0ahUKEwjf6IKGqa_LAhWIOxoKHVYVDP4QjhwIBQ&url=http%3A%2F%2Fwinemakersacademy.com%2Fdegassing-tool%2F&psig=AFQjCNEsjhly-VkgBCGikMTh94vbimhZyw&ust=1457465631605398&rct=j
