A few notes
- Researchers do not appear to be brewers
- Research has not been peer-reviewed
- Taste comparison test has not been done yet (if somebody has it please share)
- Main study is from 2016, and no taste data until now, when the only thing they needed to do is to repeat the experiment and assemble a taste panel...

Seems to me they tasted the beer and everything stopped at that point.

Cheers

At least option 2 (online community) is not mutually exclusive with all other options.
May I suggest you take it off the list, and if you wish to know, ask it as a separate question.

In my case Option 1 would be the answer but Option 2 represents me equally well.

Cheers,

I am OK with it, but if they accept cans what's the argument against odd crown caps or flip tops?

What would happen if you Connect the keg gas to the top of the Speidel?
Wouldn't gravity move the beer to the keg and keg co2 to the Speidel?

I don't use gravity. Scroll up to see my configuration. Post #69.  It's basically a Sanke transfer spear, for a Speidel.
My bad. I was responding to Macbrews and you got your message in before I pressed Send.

Here you go.
If you use the Speidel spigots use the Chrome ones not the plastic ones. If you use the norcal ones, make sure you buy the plastic cap and the silicone wrap. I bought the ball valves independently for much cheaper and added adaptors for hoses.  If you want to ferment with the spigot, just sanitize it like anything else and then cover the exit in sanitized foil.
Fill by gravity. Insert a gas quick disconnect once everything is connected and the beer going down will push the gas off the keg through the disconnect. I imagine that in addition to gravity, you will push from the top with CO2 in this case.
You can easily see the yeast/ trub level in the speidel. If it is below the level of the spigot, then transfer until you reach the level of the yeast. If it is above the level of the spigot, incline the Speidel backwards until it is below the level of the Speidel. Use something that won't slide.
I would cut the keg gas-in tube so that the beer can reach the top of the keg.
If you have more beer than the keg can take, then beer will eventually come out of the disconnect; at tha point get the disconnect out and you are done.
Keep in mind that your keg is filled to the top, so get some beer out before you connect gas or make sure gas has pressure, otherwise beer will come into the gas line.
I have done 300 beers this way, so if it can happen, I have seen it :-)

I did not understand Palmer said that. Just that it is not proven. Many combinations and impossible to test them all.

Life is so much simpler with metric

...And so much more difficult either way when pi is involved.  Not much we can do about that!  :)
If you type pi in the Google bar it will do the math for you

Most calculators have pi as well

General Homebrew Discussion / Re: How to calculate Kettle volume
« on: January 26, 2018, 10:13:41 PM »
I'm trying to find the equation to calculate the height of volume in my kettle.  I'm trying to figure out what size wort chiller will work.  I know how to calculate the total volume of a kettle, just don't know how to calculate the height of the liquid in the kettle.  For example, if I put 1 gallon of water in a 3 gallon kettle, the water height is 2.94 inches.  I don't want to keep running to my computer to use the calculator, which won't show the equation. And I don't want to keep multiplying the number of gallons I pour in a kettle by 2.94 inches, because I know that's 1 gallon, but that will change depending on the size of the kettle.

You assume a perfect cylinder:

V = (PI) * (r^2) * h

Rearranging  you get:

h = V / (PI) * (r^2)

So:

h (in) = Vwort (gallons) / 3.14159265359 * (r (in) ^2) * 0.004329


The 0.004329 factor converts cubic inches to gallons. Alternately, if using liters and cm, you use 0.001.

We were approached by Brew Your Own magazine to write a feature about Low Oxygen brewing and we accepted. It will be released in the March/April issue in mid February and plan on have a Google Hangout Live Q/A to go along with it.

General Homebrew Discussion / Re: Who filters and why, why not?
« on: November 05, 2017, 05:07:49 PM »
In the recent BYO there was an article about filtering. I have never thought or cared about it that much but it would be additional toy to play with and in that article it stated that unfiltered beer can suffer from decreased shelflife? I do care about that.
 So excluding New England IPAs, hefes, and wits, I was wondering you all‘s opinion on filtering and why? Can a decrease hop flavor? Does it increase shelflife?
Cheers
All you are stating is correct except for the hop flavor. It is the process macros use to speed up the lagering process. The hop flavor depends on what you like about hops. That said, it is not easy to avoid oxidation when using filtering processes available to us, so +1 with Denny. Get the wort to be clear into the fermenter, use a yeast that flocculates in a reasonable time, and be patient. If you are inpatient, gelatin and isinglass are good finings for ales that you want to clarify.

Yup, I guess I will add lactic acid to decrease it about 0.3 in the program and try again.
Would anyone have tried to adjust the mash at that time and how?  Same way with lactic acid?
Yep. This is what you need to do.

If your software gave you a pH of 5.4 with that grain bill, distilled water and no acid additions, software is wrong or you are using it incorrectly.  A pH of 5.7 is very reasonable. Did you add acid?
