Low pH with Best Pils Malt?
« on: January 06, 2016, 03:02:25 PM »
Has anyone found the mash pH being low when using Best Pils? I was 0.3 low yesterday. Right now I am at a brewery, and the brewer said he was 0.3 low also,  using Best. He said it had tasted a little tart when he chewed it.

I was going to do a mini mash the night before but got lazy. That needs to be part of my procedure with new malts (new to me malts, that is).

interesting you bring this up Jeff. I jumped to the conclusion my lower than expected PH might be my Ro water and carbonic acid. Ive been getting lower than expected PH with some of the lots of avangard malts....distilled or RO water and in the .2-.3 range.  This has been with the pils, munich, pale ale and vienna. 

Im starting to suspect different maltsters and or lots being the culprit, not my water.

I just ordered some weyermann floor malted pils for next batch, and hoping to see if I end up with similar variance in PH or not.

I brewed with Avangard dark Munich on Saturday, my mash ph was .2 lower that expected.  I ended up with 5.3 opposed to my targeted 5.5.

I remember Martin recommending we enter Rahr 2 row in Brunwater as 5L, to account for its higher acidity. Maybe we need to start doing something similar for Pils malts.

That's good to know.  I brewed a Blonde last weekend with Rahr 2 row and my mash pH was .27 low.  It was my first time using phosphoric acid to reduce alkalinity, so I thought I may have added too much.

im selfishly happy to hear others experience variances in PH vs brunwater/software. its been driving me crazy I'm doing something wrong.

I get a specific logarithm in software is determining the PH....just makes me wonder about different malt processes between malt manufacturers and PH.

I do that for Rahr 2-row.

Never had the low pH with Weyermann's Pils.

i cant get software to account for .3 Ph variance just by changing from 2L to 5L though....something Im missing?

100% pils 2L (10#), yellow balanced at 1.6qt/lb with RO would be 5.61. change that to 5L and PH is 5.52

edit: at 12L, you get about .3 Ph drop at 5.30 vs 5.61PH and 2L

Jeff, have you been adjusting it upwards then after getting a low reading? Just wondering how much this could affect the final beer.
I wonder if it's not just Best pils, but maybe their Vienna as well? Gah! I really don't want to have to get a pH meter...

The last 2 German Pilsner batches using Best Pils were lower than expected by .2-.3 pH (actual vs calculated by Brunwater).
I'm always within +/- .05.
Haven't seen the larger variance on my Canada Malting 2 row or TF Maris Otter, yet anyway.

I thought that was just for Rahr Pale Ale malt? I use Martin's +3L correction for that malt with great success. I haven't used it and didn't need it for the Rahr 2-Row pale.

Maybe Martin will weigh in - I remembered it being for the 2 row.

this one was at 5.25, so I let it ride. Conversion eff. was close to 100%, hit my OG. Was going for 5.55, then use lactic to drop. Next time I will try that.
