update for promash hops, yeast, and malt

[ben the brewman]

i just finished the yest file it has all of the wyeast, white labs, and all of the most common dry yeasts. the hops file is very updated with lots of new hops and the malt update is something that i found online but is very good and complete.

to install the yeast or hops file open program files, then open promash find the yeast or hop dat. file and move it to a new folder (incase you dont like the updates) then replace the files with the new ones.

to install the malt update open promash go to the grain tab then go to import and find the malt file and import it.

here are the downloads let me know if i missed anything.

Sweet thanks.

Nice. Thanks...

Yeah thanks for all the work.

[ben the brewman]

no problem this should be put where everybody can find it easily since there hasnt been an update in years.

Thanks man.

Excellent Thanks mucho!

While we are on the subject of Promash, has anyone noticed that the refractometer utility for the raw wort conversion from Brix to SG is wrong? I plugged in 17.4 Brix and it tells me the SG shold be 1.069. The correct SG value shoud be 1.074. I verified this with a table I found elsewhere and this agrees with my hydrometer reading exactly at 1.074. I'm using the default correction factor of 1.040.

ProMash is a good program, but it sure could use an update. I'd be willing to pay something for an update and I am sure others would too. You'd think that the original developer would hand it off to someone else if he has lost interest. I'm sure someone would pick up the ball and he could still rake in some royalties from it. very baffling.

Awesome! THanks so much

I think it might be because of the correction factor. I don't fully understand it yet but according to the help in promash, to find your conversion factor take readings with both instruments, convert SG to Plato then divide brix by plato. so if you did measure 1.069 (i know you didn't but wait for it) then that = 16.8 plato and 17.4/16.8 = 1.04 which matches promash. However if I use your actual numbers to figure a correction factor it comes out less than 1 which doesn't make sense so I guess I'm still confused. Plus I see what you mean about the table, and that is more like what I've experienced as well.

To make the matter even more confusing, if you google up some brix to SG conversion tables you will find that they are not all in agreement. WTF? I did find one that matched if I applied the 1.040 correction factor. I think it was published by the the USDA IIRC. I would think that all the tables available would match fairly closely, but they don't seem to and some of them mention the correction factor while others don't. This is relatively simple science and simple math, so I don't understand what the problem is. It's not a big deal as I only use the refractometer to get an approximation of my OG while boiling the wort. After that I rely on the hydrometer for both a more precise OG determination and, of course, the FG.

Here's a link to the table that my readings agree with if I use the 1.040 correction factor. It appears to have been published by the National Bureau of Standards back in 1974:

http://www.boulder.nist.gov/div838/SelectedPubs/Circular%20440%20Table%20114.pdf

My Brix reading of 17.4 corresponds to an uncorrected S.G. of 1.07151 in the table provided. Then applying the 1.040 correction to the decimal portion .07151 = 0.0744 Adding back the 1 gives us 1.0744 which I think is the correct answer as it jives with my hydrometer reading of 1.074

Sweet! I replied to this just so I can find it tomorrow when I'm at work :D
