    RO Filters

    Hello all, I am in an area of very hard water (>250ppm) and was looking at a 3-stage RO filter to dilute my water for pilsners. Recently, I've been boiling to soften which is going to be crazy expensive. I'm wondering which one to go for. I was looking at the following: Option 1 (£55) Option 2...

    Residual alkalinity & lactic acid

    I get my water report from thames water and they quote deviations about mean in concentration of minerals between samples so ive got pretty good confience that the Cl and SO4 are 25-30ppm each. Will try boost them up a bit. I had found that before making any adjustments my beers did lack a lot...

    THANKS! will adding CaS04 and caCl also help? My water also happens to be really low in chlorides and sulphates so i dont think I'll making it too minerally by adding that in

    Residual alkalinity & lactic acid

    I'm in an area with LOADS of chalk in the tap water so my alkalinity hardness is over 200ppm. What have people found is the best way to remove alkalinity from water?

    Have just looked back over my notes and realised that there was another common factor with spoiling batches. I think i have been adding too much lactic acid! Tested my pH meter in buffering solution and realised that after i calibrate it, it will automatically turn off and then totally lose the...

    Recurring infection - old irish moss??

    Its a counterflow chiller, so wort goes through one pipe and cold water goes in the opposite direction

    Recurring infection - old irish moss??

    I think my sanitation procedure is quite clinical. Normally run warm PBW for a few hours after brewday, circulating through the wort chiller and then followed by boiling water circulating for half an hour or so. Ill soak fermenter in PBW overnight before and then keep it in starsan from the...

    Recurring infection - old irish moss??

    Relatively new to brewing and have done about 15 brews total now but have had recurring infections on 3 out of the last 4 batches but never before. I always felt like before i got away with a lot of unsanitory practice and beer turned out fine (although still with a couple of moderate off...
