5.1pH?
« on: October 06, 2015, 05:42:04 PM »
Brew Day!  Always a good day-  mashed in added my salts and lactic acid- doughed in and stirred for ~5 min. Took a sample and set on the kitchen counter. Went back out side and got side tracked. Went in, calibrated pH meter and took pH reading around 30min mark into 60 min mash. PH was 5.15 at room temp 74.(my meter also has temp adjustment). My target was between 5.2/5.3.  This is a west coast style IPA so im bot super worried just curious what i can expect.

Thoughts?

Thnx

Myself I would probably do nothing. If you were that worried about it toss in what ever amount of baking soda brunwater recommends for a 0.5-1.0 higher pH.

In my opinion that is a great pH for a hoppy beer.  I shoot for low pH on beers like this.

5.15 rounds to 5.2.  Bru'n Water rounds the same way.  If you find that Bru'n Water systematically overestimates the pH then you may want to take that into account, but for now I wouldn't change anything.

my version doesn't round...if 5.15 thats what it projects.

One thing to remember is that auto temp correction in a pH meter only adjusts for the electrical response of the probe at a temperature other than what it is calibrated for (20C usually).  There is another, bigger difference which is that the mash pH actually changes; as temperature goes up, more hydrogen ions dissociate and the pH decreases.

The reference temperature of 5.2 is usually quoted at mash temperature, and would be closer to 5.5 at room temp.  The range for conversion is pretty big, so I wouldn't sweat it.  Your pH is lower than I go for an IPA, but I've never tried it.
Please do not reply if your[sic] an evil alien!

My understanding and practice is optimal mash ph at room temp is 5.3-5.6 ( 5.2 ok and sometimes desirable for certain beers ). 

Good article by Kai for reference.  http://braukaiser.com/blog/blog/2011/03/02/about-ph-targets-and-temperature/

I've found I like the lower pH better in many instances.  it makes the beer seem brighter and makes it "pop" more.  at least to me anyway.

SMELLING AMAZING!!!  Dryhopped with 1oz Mosaic, Citra, Galaxy AND 1oz of Summer (found some in the freezer!)
