Your site lists old research yet now you argue that we are light years ahead? I was waiting for you to make the obvious point about the conclusion I posted from the paper but you didn't. Adept is your own assessment. Last time I was driven off the site by the 'hot side aeration is a myth'...

I'm not finding it and have asked for it. I posted what I found. Please feel free to do the same. But, by the time you do, if you do, well see below.

OK. Now I get it. When you said we I looked a little further. You are this Derek Scott? "Derek is an electrical engineer who started brewing, like many, with an extract kit gifted from his wife on his birthday in 2015." Personally, most engineers I know would take a long hard look at their...

Basic science. When observations don't match the calculations you need to re-examine both. I do my part by repeatedly examining old bottles of beer.

From my reading and experience, high alcohol dark beers with low hops seem to age better. Again, 31 year old research showed this as a solved problem. Change the cap. Can anyone point me to recent literature saying this is still a problem? It doesn't take much to pick potential holes in that...

"The phenomenon does not occur in bottles sealed with aluminum spot-lined crowns or in cans." There is solace in the conclusion. Like I said, cherry picking lines out of old studies isn't useful. This was a known problem in 1987 but there was already a solution put forth. Don't use PVC in...

Counter-intuitive and counter my experience. I gotta dump all my beer bottled beer before 6 months? At least I can read this study. http://www.agraria.com.br/extranet/arquivos/agromalte_arquivo/entrada_de_ar_tampas_de_polivinil_-_ing.pdf Note its age and the conclusion that material plays a...

Well, I started brewing before my join date here. I still have a few of my original brews. When I open them they aren't flat. I won't say they are perfectly carbed, but they have a positive pressure. If it takes longer than that to leak out at positive pressure then how long before ingress...

Can 't find them easily. I didn't post in the threads and the forum software doesn't make it easy. People were throwing this about as if it was the norm and expected behavior. After thinking about my old carbed bottles I realized this just didn't sound right. But, like I said, I don't come...

People are posting as if this is the norm yet I haven't run into it. Is this a cap issue or a crappy capper? I vaguely remember people talking about being able to twist their caps by hand after installing? Is this from bad technique or bad cappers? Either way, this isn't a universal cap...

I don't come here much anymore because useful information seems to be getting less and less. Now I see people talking about how beer goes bad because of bottle caps letting in oxygen? I have some old beers that still go 'psssst' when I open them. If they are holding carbonation then how the...

Grain does not come from one place with one property. You are chasing a moving target. Use water chemistry primarily for pH control and add any thing you do for flavor after that, unless of course you can easily adjust your water chemistry to account for that. Otherwise, brewing is like...

No. Anything pre-boil needs to be clean. Anything post boil needs to be sanitized.

I've used that avatar before.

I'm guessing without looking up his numbers the bubbler would be analogous to shaking. He claims 50% more oxygen with the electrolysis so I'm guessing 8ppm and 12ppm. That would be right in the ballpark of where you want to be IF it works in wort. However, without a DO meter and lots of other...
