Thought this might be of use to others. Martin noted in this thread httpss://www.homebrewersassociation.org/forum/index.php?topic=14478.0

(a little over a year ago) that you can correct for the additional acidity of Rahr Pale Ale malt by upping the lovibond rating by 3L in BrunWater. So, for example, my sack of RPA rated at 3.7L should be entered as 6.7L in Bru'nWater for the sake of pH estimation. 

 

Martin, do you still find that to be an accurate workaround for pH estimation with this malt?

 

Denny, I noticed you chimed in there too, have you used this adjustment to account for the increased acidity of Rahr Pale Ale malt? What have you found that works?

 

Any further guidance on the same effect that Kai noted with wheat malts and their high distilled water pH?

I use the Rahr pale, not pale ale.  I don't know if the same correction is applicable, so I haven't done it.  I'd be interested to know if it applies to the pale, too, though.

Well, now I'm confused. Which one of these are you talking about. I am referring to the one called Pale Ale in the chart listed at the link. That is the one with the known acidity, no?

Hmm? I do think it is still applicable. I just brewed a Porter last night and my observed pH was a tenth lower than the prediction. As I am writing this, I realized that I had not applied the 3L correction when I input my Rahr pale malt.  Oops!

FWIW, I like the Rahr Pale Ale malt.  There is the standard Rahr domestic 2-row and then there is the Rahr Pale Ale... 2 separate products.  The RPA is a really nice product and this came up in the other pH thread... my blonde made with RPA may have been saved by the fact that this malt lowers pH more than you might assume for a base malt of this color.  It makes really nice beers and the added acidity is a plus for high-bicarb/alkalinity brewers.

What I'm talking about is what they call "standard 2 row".

Got it thanks Denny.

Yeah while I haven't tried it yet I have heard good things from you and many others about it so I bought a sack of it a few weeks ago. Reasonably priced too. The one time I used Briess Pale Ale I got an inexplicably low yield from it so I won't try that again. I just need to remember to use Martin's "correction" when estimating my mash.
