That is very helpful to know!  Thanks.  I'm going to test my new sack of Avengard Pils tonight if I get a chance.

that would be great. would help to see if this is incidental or norm.

Last weekend I did a pils and I adjusted it to 10 in software and ended  up almost right on vs projected.


Edit: I've only mini mash tested this sack of Avangard pils. I will be getting another in March and will be testing that also to see if it's consistent.

Whoa, 10L and you hit your mark??? Holy crap.

open up brunwater, put 1lb of pils at 2srm with 1.76qt distilled water and no salts. PH estimate is 5.69. change the srm to 10 and estimated PH is 5.46.....right where I came in on mini mash test.

I still can't get over that.

some acid treatment and not so surprising.

Avengard Pils was 5.2 at 34C/93F - I was in a hurry, so it was a bit warm still after mashing at 151F for 10 minutes.

Well that gives more credence to them acidifying their malts similar to Rahr's 2 row - I remember Martin thinking so. As long as it's consistently around that pH, at least we could account for it in software. Was that in distilled ? Thanks for the info !

Hmm, that is low for a base malt, but the temperature was too high. That was a test mash, you had the time to let it cool. The other caution is that you do need to go much longer than 10 minutes. A half hour isn't unreasonable.

I've noted that initially low pH's tend to rise and initially high pH's tend to fall during the mashing period. They happen to point to a pH of around 5.4. It's a weird phenomena that I've also shared with AJ DeLange to see if we can figure out what's going on. Its probably something to do with the phosphate buffering system in malt.

I will run it again, Martin and be sure to let it rest at 150F for 30 and then chill the sample to 70F - I did the check early on Saturday before heading out a a day trip with some friends - they arrived early, so I had to cut it short.  Still I bet it will be lower than expected.  But I wanted to pass it along and wanted to note the short mash time and high temp, so that it would be noted by others.

That wouldn't surprise me at all. Calcium-Phosphate stability curves get pretty complicated. They are heavily influenced by concentrations of both sugar and protein in solution. This would obviously shift over time as the mash proceeds and more sugars are being put into solution.

Low pH with Best Pils Malt?
« Reply #143 on: February 13, 2016, 06:18:11 am »
I followed martins advice on length of the mini mash and did 30minutes . I also decided to do one with distilled and one with my RO water. Results the avangard Pils were 5.38PH distilled, 5.41PH for RO.

Previous 10 minute mash vs the 30minute mash was .02  (5.40PH 10min, 5.38PH 30min w/distilled)
