Low pH with Best Pils Malt?

Martin, is there a simple procedure a brewer can perform on a small malt sample to determine its relative acidity in a mash?  Something along the lines of “take X grams of pulverized malt, add to Y grams of distilled H2O at 68 degrees F, wait Z minutes, record pH?”

I’m sure there are plenty of people on this forum who would be happy to perform this sort of data gathering (and send you the results), so having a standard process seems like good idea.  And if there is also a simple way to translate that discovered pH value to an adjusted “L” value to plug into Brunwater to improve its performance, that would be good to know.

It’s quite simple really. All you need to do is get the malt analysis info. For instance this is my vienna malt I have http://www.weyermann.de/pdf_analyses/q204-002360-01.pdf

Why must we always make more work for ourselves, all the malsters have lot analysis on the malt. More over how do you know how to properly mash the malt without the specs.
Simple as that :wink:

It seems to me the issue is with conflicting results to what the analyses is saying…

The lot analysis from Country Malt Group does not have pH listed. Best Malz gives a range. Lot Analysis entry is not apparent on the Best Web Page.

No, Weyermann just lists general specs as well. No one here is getting lot analysis.
If north country is lacking, one should contact best. They are quick responders.

Mashed 0.25 lbs in a half quart of distilled water at 155F in a SS coffee thermos. Calibrated the Milwaukee 101 with fresh 7 and 4 solutions. Then measured the pH after my usual 10 minutes. Result was 5.55 pH.

and is 5.8ish Ph what you would have expected?

Yes. The range Best has on their page is 5.8-6.1. So it measured low.

I know this has been discussed a million times, but is it possible that some analysis sheets are listing pH at mash temp rather then at room temp?

The standard reference is at room temperature. It has been stated that the German Brewing texts are clear about that.

Edit-it would be lower at temperature of the mash by about .3-.35. I measured at room temperature.

Thanks for that, Jeff.  I’ve never checked it.

i want to do same thing with avangard pils…having trouble locating any specs on it though.

That might just be for this lot of pils malt.

FWIW best is my house pils and using Brewers Friend I’ve been getting accurate predictions

When you get right down to it, the base malt is what dominates the resulting wort pH for most brews. The distilled water pH of typical pale and pils malts should fall in the 5.7 to 5.8 range. If the distilled water pH in a test came up much different than that, some adjustments to your calculations should be made.

and for that presume that’s what you have loaded into your software. I want to test my house base malts from Avangard and see what it comes out as.

Jim, I have shared data from Best Pils Lot number 12665. Malt has variance as an agricultural product. This one seems a little acidic for whatever reason.

What lot numbers have you had better luck with? As a Chief Engineer used to say, can you show us your data?

Can’t we just throw some 5.2 stabilizer in there?

Absolutely.  :wink:
