Nice and easy, I'll think I will make one of these, replaceable if it breaks

It might work, and you can get away with it, but it is far from optimumMark1964 said:i think you will find it is true. When your dropping wort into a fermenter thats all it needs.
Don't need anything fancy for 5 gallons depending on how much of a workout you want I used to use a stainless holey spoon, but have moved over to a 'paint mixer paddle' in a cordless drill . . . 15 seconds and done!Mark1964 said:No need for fancy stirring devices

CO2 dissolves easily (relatively) into water, Oxygen less so . . . why does it take so long to properly carbonate a beer . . . Because it's being produced slowly . . .I am not a believer in the theory that the CO2 is produced and goes into the head space of the bottle . . .and then dissolves back over the next two weeks . . . It basically saturates the Beer and head space at the same partial pressures. . . In conditioning you are producing a very high level of CO2 in the beer, when aerating you are producing a much lower saturation of Oxygen (8-12ppm). The important factor affecting speed of absorption is the size of the bubbles . . . the smaller the bubble the greater the surface area and the more gas can exchange . . . using a paint mixer at high speed produces masses of tiny bubbles, all distributed throughout the beer, allowing rapid gas exchange . . . and so a short period of mixing is needed. . . 15 seconds is pretty short . . . but then I normally flush the head space with oxygen before starting :whistle: :whistle:Andyhull said:Im not sure about airation taking place in 15 seconds from simply using a rotating airation paddle!
My thoughts on this are due to the process we go through to get CO2 to be absorbed into our brews, they are stored at a low temprature under pressure for around 2 weeks to alow the gas to absorbe into the liqud.
How can swishing air around in a liquid for a short time add air to the liquid, surely the resultant bubbles just rise to the surface as a foam!

My god I envy you!! I always feel that my beers have the potential for improvement, even the very best ones make me ask myself "is there any way that I could have made this better?" whereas you are clearly producing stunning beer that you are over the moon with, that you couldn't dream of improving!
Really not very open minded of you, how confidently can you say your beers were the best they could be? Is there a chance that aerating correctly may have improved them?
The thing is this is not a theory, it is proven scientific fact that correct aeration will give you better yeast health and therefore fermentation. Correct the smaller batch size may have smaller benefits, but as people here are learning, and many are moving to larger brew lengths and higher gravity wort, things like this really become more important. Coming along and dismissing people's efforts on trying to improve their process and product isn't helping anyone, as a moderator I would have thought you would have been one of the first to realise this.

That's not correct now is it? He stated that wort did not need to be aeratedandyhull said:Where does Mark say in his post that he couldn't dream of improving his beers?
All he stated was that he hasn't had a **** brew in 3 years and that he hasn't had to stir the wort to acieve it!!!
