Mineral additions to sparge water?

(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!

Mineral additions to sparge water?

Post by Lanky94 » Thu Dec 20, 2018 11:29 pm

Hello all.

I am about to jump from BIAB to 3 vessel with a plan to fly sparge. I am reasonably content with water treatment, but for those who use a 3 vessel system, do you treat your strike liquor to the desired profile only, or both strike and sparge.?

I look forward to your expertise.

Any treatment will depend upon the mineral content of the water used.

Primarily it is essential to adjust alkalinity to that suitable for the style and grist used. As sugars progressively dimish during fly sparging, pH rises as the sparge continues unless measures are taken. Sparge liquor alkalinity should be less than for the mash and as calcium reduces pH, unless the sparge water has adequate cacium, salts should be added.
Without patience, life becomes difficult and the sooner it's finished, the better.

HI Eric.
So provided I have the alkalinity correct during the mash, would I use normal untreated sparge water and then measure the ph of my final running's and go from there?

No, too late by then. As Eric said you need to lower the sparge water alkalinity, somewhere between 20-30 ppm, you want to avoid pH rising and undoing all the good work of getting it into the right range in the mash. You are looking for your final runnings to be under pH 6 when the sparge is finished.

Ok got it. Thanks Orlando. On a side note, I am moving to Norfolk soon, where I seem to the remember the water is hard and probably quite alkaline. I would imagine its OK for darker beers, but requires treatment for pale ales etc. As you live there, do you have any top tips on water treatment for this area please?

Sure. First thing you do is become a member of Norwich Brewing Club . Then get yourself a water report from wallybrew on here. The main problem with our water is the alkalinity levels. Get rid of the appropriate amout of that and it's possible to brew quite a lot of beer styles with the water as is.

Whereabouts are you moving to?

I hope it's alright to jump in here.
Are you saying that I was making a stout where I lower my hard water from alkalinity 210 to 90 ppm, would I still need to lower my sparge water even lower to 20-30ppm?
thanks

Jump in whenever you like, the water's lovely. :D

For a Stout, down to 150 might be a better target, as often Stouts will have a grain bill that provides quite a lot of acidity anyway. But your sparge water should always be 20-30 ppm regardless.

I would welcome joining the club in Norwich deffo. How often do you meet?

I move to Marham in July (Narfalk lad anyhow, born in Narwich).

Do Ineed an RO system, or have been living in the USA too long to think that? lol!
