Hello,
I've been experiencing efficiency differences of up to 10% where the only significant variables between brews has been the water profile (addition of gypsum & epsom salts).
I'm speculating that it's a pH problem. I haven't tested it yet but I've got some test strips in the mail (cheers Ross).
I was also going to get my hands on some phosphoric acid too. However, I've discovered a product from Five Star called 5.2 pH Stabilizer. There is a little bit of information around about it. For example, <a href=http://hbd.org/hbd/archive/4665.html#4665-7>this</a> from HomeBrewDigest. I didn't have any success searching this forum.
I haven't been able to find much information about how much of this stuff you get in the container or how much of it you need to use. Grain and Grape have a product listed called "5.2 pH Stabilizer", no brand name, no picture, no information. Its $25. I'll contact them for some more information.
Has anyone used this stuff? Can you tell us a little bit about it?
thanks
Scott
