Liquor additions - for the mash or boil?

(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!

Liquor additions - for the mash or boil?

Post by Jocky » Thu Apr 02, 2015 7:40 am

With me about to brew with a new water source I thought I should review what I'm doing with water treatment.

Using the GW water calculator I've established I'll have 120ppm of calcium left in my water after CRS treatment.

For my other additions (50-70ppm of Calcium, Sulphate and Chloride) should I just split them across boil and mash?

And should I be treating based upon the water used for the mash or end boil volume?

How you split your additions is a personal choice but given that you have enough calcium in your water there is little to be gained by adding them to the sparge or mash so putting them in the copper would be best.

Ideally you want to know what you end up with in the beer so you need to calculate how much of a concentration factor you have and add the appropriate amount of salts to get the final beer levels correct. If you do not sparge your hops you will have to add the volume retained by the hops to the volume of wort you get in the fermenter as being the final volume of beer.

Hope that makes sense
