dls additions

[paulg]

I have recieved my water report from murphys
ph 7.28
nitrate 4.1
calcium 78
magnesium9
chloride 18.18
sulphate 5.87
alkalinity 220 as CaCO3
recommendation of ams 26 ml per 25 litrs liquor
dwb 15 gr per 25 litres beer made

this compares well with my local test here in greece(see previous post ,it gave a reading of 219 alk) and the salfert test but looking at my previous notes re my liquor treatment the crs addition is the same as I was using BUT the dls addition I was under the impression I should treat all liquor
ie for my typical brewday 25 litres beer requires about 40 litres liquor due to evaporation losses and trub /dead space

so instead of using dls at a rate of 15/26 =0.6 per litre I would have been using 40 x 0.6=24 grams instead of 15 gram so about 60 % to much
thats if I understand it correctly
what are the results of this as a taste/efficiecy thing any ideas
thanks Paul

I understand your confusion and a lot of people on this forum disagree on whether to treat, total liquor or final volume, with DLS.

Personally i treat for the final volume of beer because salts dont evaporate in the copper (boiler) they just concentrate, and the other reason is taste. I found when adding a large ammouts of salts it can dry the beer out and be slightly astringent especially when sulphates get high (although this may be what you want?).

Basically brew a beer and adjust the DWB (dls mix) to suit your taste, just like seasoning food but more difficult

I calculate CRS based on the total volume of water used and DLS based on the brew length. The CRS goes in the HLT and the DLS goes into the mash. The main reason I do it this way is because someone told me to....

thanks guys
I had been treating all the liquor volume with both crs and dls
the dls split into mash and pre boil quantities I have previosly complained of bitter taste(astringency?) in my bitters my milds and dark ales not so much
of course with my acidic water I am using very little dls in dark beers so if I am over treating the liquor this could explain the problems
next brew i will try treating to brew length not total pre boil volume
