Hello,

I am building APA water for an upcoming brew, from RO/DI water.

 

I am adding this to 12 gallons of water

Gypsum Calc. Chloride Epsom Salt

CaSO4 CaCl2 MgSO4

12 7 4 - grams each addition

 

To end up with this

 
Calcium Magnesium Sodium Chloride Sulfate Chloride / Sulfate  
(Ca ppm) (Mg ppm) (Na ppm) (Cl ppm) (SO4 ppm) 
Mash + Sparge Water Profile: 82 8 0 59 152 0.39

 

I am cautious to go any higher on the sulfate / chloride, thoughts? Suggestions?

 

thanks Kevin

 

EDIT - sorry about the formatting... it was in HTML boxes when created the post.

The formatting is a bit scrambled on my display, but the final numbers look like a good start. If you like that, you can try higher SO4 next time. You may find that you still need to lower the pH, depending on the malts.

What Brauer said. Looks like a fine profile for a pale ale. Looks like you are using some water software of some kind so just make sure your mash pH is correct with your grist and if not adjust accordingly.

I agree with brauer.  for a pale ale that will be great.  if you really like the sulfate kick you can keep pushing that number up.  I often go up to 300-350 ppm for IPAs.

Do you have an idea of where this leaves your mash pH?

I was assuming that was already in line but yes, the mash pH is even more important than those other water numbers.

Hello,

I used EZ Water Calculator to get these numbers, the sheet always works well for me.

 

The sheet said my ph was 5.5 - the sheet suggests 5.4 to 5.6 as the target mash ph to shoot for.

 

thanks 

Kevin

I typically go for 5.3 or 5.4 depending on the beer.  That's just me though.

I would expand that range to 5.2-5.6 based on what I have read and experienced. A pH of 5.5 should be OK. One thing to think about though would be to get a pH meter and test your mash pH (at room temp) to confirm what the calculator is predicting. The calculators can be pretty off at times and different malts can bring an unpredicted amount (not correlated with malt type/color) of acidity to your mash. Rahr Pale Ale specifically is known to be more acidic than the calculators will predict. I am with Morty too in that I like to shoot for 5.3-5.4 on most beers and only occasionally stray from that range.

I've had really excellent luck with bru'n water - people with different water or malts may experience something different though.  I use colorpHast strips to check my pH and very rarely (1 out of 20) do I not land pretty much exactly where it predicted.  usually in these cases I'm not drastically off, just 0.2 and I throw in some gypsum or something and all is right with the world.  even doing nothing in these cases I would have been fine.

 

as for the pH goal, 5.3 is my go to for anything that is hoppy.  I think the acidity is just the ticket for these beers.  if it's something more malty I'll do 5.4 or 5.5.

Fixed for me

 

I'd probably consider 5.2 if I trusted the colorpHast strips more but I figure 5.3 gives me a little bit of wiggle room since I don't really have great resolution and trust in the strips.

The resolution on my meter is great :)

Agree with the acidity in hoppy beers, I think it helps keep them bright but I've not made any side to side examples to confirm. I should clarify too that I, like Ken have noticed that BrunWater will slightly overestimate the pH from time to time and when I say shoot for 5.3-5.4 it's frequently 5.2-5.3 on my meter. I like to keep it from straying under 5.2. Hoppy beers and Saison (which frequently aren't 2 different things) where I will most often shoot for the lower end.

did you know I cut my strips in half so I get twice as many readings out of the little box?  :D

What's the shelf life?

that could be the case for me and I might not know it.  good point on the saison, even a non-hoppy saison would probably benefit from a low pH.

What's the shelf life?

 

I've probably gone past what is recommended but they still seem to be agreeing with what bru'n water predicts.  at some point I could probably just stop measuring and it wouldn't make much difference.

I have heard some cut them in thirds .. I still like my mete but I like toys.

Thanks for all the help guys.

 

I will shoot for 5.3 in the future, I appreciate the feedback.

 

I am always wanting to purchase new brew stuff, but I have not purchased a ph meter yet.

From what folks who have them say, the EZ water  sheet gets me/them close enough, or spot on to the calculated number with the hassle of calibrating the meter and hoping it is accurate.

 

Sorry if that upsets some folks.

 

thanks Kevin

Welcome to the forum, haeffnkr!

 

Thanks, I followed Ken L here.

He has helped me a lot in the past.

 

thanks Kevin
