Default Post Your Final Beer pH

I am interested in compiling finished beer pH. I am looking for beers that have finished fermenting and are degassed if they have been carbonated. KCBeersnob posted a lot of good info in another thread of mine and I will consolidate that information here as well.

WY1056:

  • Pale Ale-4.92
  • Rye IPA - 4.78
  • "Snow Cone" IPA - 4.83
  • Pale Ale - 4.54 (post boil pH 5.28)

WLP001:
  • American IPA - 5.00
  • Session IPA - 4.84
  • West Coast Blaster - 4.68-4.75 (Dependent on aeration level, but no to normal aeration, post-boil pH 5.15)
  • West Coast Blaster - 4.51 (aerated very highly, post-boil pH 5.15)
  • Black IPA - 4.63
  • Pale Ale - 4.80
  • American IPA - 4.89

WLP 004:
  • Dry Stout - 4.01 (post-boil pH 5.09)
  • Irish ale - 4.18 (post-boil pH was 5.15)
  • Oatmeal Stout - 4.51

WY1028:
  • Porter - 4.55

WY1968:
  • Oatmeal Stout - 4.43
  • Bitter - 4.10 (post-boil pH 5.30)
  • Amber Ale - 4.30 (post-boil pH 5.21)
  • Bitter - 4.06 (post-boil pH 5.30)
  • Strong Amber Ale - 4.30 (post-boil pH 5.05)
  • Bitter - 4.20 (post-boil pH 5.38)
  • Bitter Best - 4.30 (post-boil pH 5.15)

Brewlabs TV3 1000 (similar to WY1968):
  • Mild Ale - 4.05 (post-boil pH 5.15)
  • Bitter - 4.10 (post-boil pH 5.20)
  • Bitter - 4.00 (post boil pH 5.20)
  • Mild Ale - 4.15 (post boil pH 5.15)
  • Bitter - 4.12 (post boil pH 5.17)
  • Bitter - 4.12 (post boil pH 5.10)
  • Best Bitter - 4.07 (post boil pH 5.13)
  • Bitter - 4.17 (post boil pH 5.12)
  • Best Bitter - 4.10 (post boil pH 5.22)
  • Bitter - 3.95 (post boil pH 5.10)
  • Bitter - 4.03 (post boil pH 5.22)
  • Best Bitter - 4.20 (post boil pH 5.18)
  • Dark Mild - 4.15 (post boil pH 5.10)

WLP060:
  • IPA - 4.47 (post-boil 5.43)

WLP051:
  • American IPA - 4.61 (post-boil 5.35)

Good idea. Two things:

I think this data is most helpful if you also post the knockout pH, so it is possible to identify the extent to which the strain affects final beer pH. I initially got into this ongoing experiment, because I was finding my beers finished high when using 1056. Now I know this strain is a low acid producer that I need to make sure my knockout pH should ideally be <5.2, although I need to repeat the "experiment" to confirm.

I think it would be good to cross-link the threads for reference: http://www.homebrewtalk.com/f13/final-ph-beer-high-451395/

What differences in the final beer are you detecting? (Taste, color, clarity, etc.)

Done, and thanks for linking the cross reference in both threads

I, personally, haven't been able to do a side by side test of the same beer with only different pH Levels (I lack phosphoric acid to adjust with). But if Gordon Strong can be trusted, it should affect the taste, he describes a correct pH beer as being brighter and fresher, and the stability of the beer.


I'm sure there are more of us that monitor this sort of thing. Help us out with all the data points you can. I'm interested in all yeast strains, types of beer, really anything you have.

Added, thanks KC. I also added a couple more of mine, plus another member contacted me and is going to email me his yeast spread sheet from the last 14 years he's been brewing! Big hat tip to Lincs for sharing his information.

It would be really cool if there could be a standard reference for the wort so more accurate info could be had. IE starter using 1L distilled water @ 1.040, measure KO and post ferment.

Lot of other variables that go into it as well, dissolved oxygen levels, yeast nutrients available, ect., but if you ever do a controlled experiment I would be interested to see what you get.

Interesting results so far. Here's another one for you:

WLP051
American IPA: 4.61 (post-boil 5.35)

Very strange: the post-boil pH actually rose slightly compared to the pre-boil pH (5.32). The meter was freshly calibrated and then re-verified in the 4.01 solution after noticing the strange measurement.
