Boiling then CRS

(That's water to the rest of us!) Beer is about 95% water, so if you want to discuss water treatment, filtering etc this is the place to do it!

Boiling then CRS

Post by shuggie159 » Fri Jul 08, 2011 4:25 pm

I live in E Surrey with a water profile 200+ caco3

Forgive me if its a stupid question, but....

From all the threads I know hardness and alkalinity are not the same thing, but if 'boiling' is one of the oiptions at the top of Grahams calculator, surely it could be used in conjunction with CRS.

Is there any milage in, 1) boiling hard water to remove the 'temporary hardness' and then 2) treating the cooled water, drained off the precipitate, with CRS?

I've got a alkalinity kit ordered, so I will soon know the answer. I'm not so keen on all the magic potions, but recognise the difference the water quality makes to the finished product.

Boiling removes calcium which you have to put back.

CRS removes alkalinity and leaves calcium intact so you don't have to put any/or as much back in if you live in a hard water area (And I'm using the term Hard in it's correct usage here).

Pretreating by boiling to remove the alkalinity seems to me to be a very expensive way of doing things (in terms of money and time). I can appreciate that it was done that way in times gone by when they didn't have access to meters and indicators that enable us to use our magic solutions to do the job. . . The reason I don't particularly like to use CRS is because it adds both chloride and sulphate ions . .I would prefer to choose which of the two I want to adjust . . . so I use sulphuric or hydrochloric acids rather than a blend

Boiling your water is much safer. To boil your water the carbonate is reduced to a manageable level. Yes, calcium is reduced as well, but that is restored by gypsum additions. The thing is with boiling is that you have a more-or-less clean slate. You can then add calcium sulphate or calcium chloride to suit your preferred sulphate : chloride balance.

The problem with CRS is that it shoves lots of chloride into the water, far more that is found naturally in any water, and if you then use DLS afterwards you are shoving lots more chloride into the water. If you live in a very "chalky" area, you have very little control over your water balance if you are using Murphy's flagship products. I dunno what it is about Murphy's and chloride; I assume that the directors must have shares in a salt mine somewhere. But they do seem to be somewhat out of touch with modern brewing practice.

There is little point in boiling and using CRS in conjunction, unless you are fine-tuning, of course.
