CRS alternatives

is there another source of Sulphuric now that Murphy's have stopped supplying the HB market?

APC Pure.

thanks - is this food grade? Have you used their stuff?

Mine arrived yesterday! It is food-grade.

Thanks for the info. Do you have a link for ordering? Thanks

Here you can choose your strength. I went for 25%, though looking at the choices now, I'd have probably gone for the 1M, as, similar to other suppliers they don't specify whether the 25% is v/v, w/v or w/w. You know where you are with Molarity.

Thanks for that Dave. What's the situation with Hydrochloric? Can you get it at a decent % (or M) without having to dilute?

APC do that as well, I think. Not sure about the dilutions. I bought mine from eBay and diluted myself.

hmm OK. Was it easy to do? Any guide for this?

Just had a look and APC do all manner of dilution.

I'm now out of sulphuric acid.

After some helpful discussion with Eric after me finding a bottle of AMS lurking in my beer fridge, I am going to trial a new water profile with just using AMS/CRS and gypsum/Cal chloride.

For anyone interested, I am brewing an APA using west coast yeast (MJ) and this is the profile I will try.

• Batch Size (Litres): 23
  Mash Water (Litres): 16.50
  Sparge Water (Litres): 17.00
  Starting tap water CAC03: 228
  Starting Tap Water SO4: 72
  Starting Tap Water CL: 46
  Starting Tap Water CA: 111
  Mash Water CRS (ml): 18.2
  Sparge Water CRS (ml): 18.7
  Mash Water CAC03: 28
  Sparge Water CAC03: 26
  Mash Water PH: 5.25
  Gypsum Mash (gm's): 3.5
  Gypsum Boiler (gm's): 3.6
  Cal Chloride Mash (gm's): 1.0
  Cal Chloride Boiler (gm's): 1.0
  Total Gypsum Addition (gm's): 7.0
  Total Cal Chloride Addition (gm's): 2.0
  Final Sulphate (ppm): 287
  Final Chloride (ppm): 145
  Final Calcium (ppm): 176
  Sulphate:Chloride Ratio: 2.0

When I looked I thought there was only one food grade strength?

That looks fine to me. If anything I might get the sparge water alk down a little, but 26 certainly isn't out of the park.

Yeah, only one that stated food grade, but to be honest I'm not really bothered about that. We use them in such small quantities I don't think it matters much. Because it doesn't say food grade doesn't mean there is something awful in there - apart from acid of course
