Big RIS water profile

I’m brewing a big RIS at around 1.110 OG. I use almost 25% of specialty grains including roasted barley and carafa.

Can anyone give me advice on what water profile should I use?

For now I have something like this:

[quote]Starting Water (ppm):
Ca: 55
Mg: 34
Na: 0
Cl: 4,9
SO4: 39,4
HCO3: 473

Mash / Sparge Vol (l): 40 / 30
RO or distilled %: 0% / 0%

Total Grain (lb): 22,2

Adjustments (grams) Mash / Boil Kettle:
CaSO4: 2 / 1,5
CaCl2: 4 / 3
MgSO4: 0 / 0
NaHCO3: 0 / 0
CaCO3: 0 / 0
Lactic Acid (ml): 9
Sauermalz (oz): 0

Mash Water / Total water (ppm):
Ca: 94 / 94
Mg: 34 / 34
Na: 0 / 0
Cl: 53 / 53
SO4: 67 / 67
Cl to SO4 Ratio: 0,79 / 0,79

Alkalinity (CaCO3): 148
RA: 61
Estimated pH: 5,54
(room temp) [/quote]

I still need a lot of lactic acid to lower down the pH which is kinda strange taking into account the amount of roasted malts.

What do you guys think?

If you’re referring to water profile in Brunwater, I’d use black bitter for a RIS.

Knowing your grain bill would help but I think something is off with your volumes.

You’re mashing in with 40L? and sparging with 30L? Almost 18 gallons of water for 22 lbs of grain?

I agree that the black bitter or balanced should be good targets. Because of the Mg content in the tap water, it appears that dilution may be called for. That will help with the high alkalinity
