pH reading gone wrong...??

Great points as always Martin. Thx for that. Fortunately, I have enjoyed every beer since I began this process. I haven’t noticed any thin beers yet. It seems to work great for me on my system.

I found 10% Phosphoric Acid even at a dose rate of 1/8 tsp too strong for the RO/distilled I use, so I tried 1 tsp Ascorbic Acid powder along with 1 tsp CaCl in the mash this last batch. The phosphoric would drop the pH too low, too fast. Maybe it’s because at zero or near zero TDS there was nothing to buffer it.

There are reports of AA creating hydrogen peroxide in the absence of sulfur but so far so good in the mash.  I’ve not noticed any darkening or off flavors.

I also use Brewtan B, Active Dry Yeast and sugar to create my brewhaus liquor and add flavor salts to the boil.
