Too Much Gypsum w/AB Clone?

I know JP was soliciting 'problem beers' awhile back for an upcoming show/project. You may wish to contact him and see if he still needs some if you are planning on dumping it anyway.

Martin - thanks. I've used upwards of 300 ppm SO4 before with no issue as well. My mash pH was 5.35 measured around 25C on a ATC pH meter. End runnings gravity were 1.012.

Timmy your mash ph was too low. Measure your beer ph and see if it is above 4.1.

5.35 is good at mash temp, but it reads about 0.3 higher at room temp. So your mash ph was about 5.05.

Hmph, I am out of calibration solution but will check it hoping my meter is not too out of wack.

Thnx Spider. I'll e-mail him.

Tasted it again today. Still has the off character but it seems to be more in the aroma than the flavor. Beer pH is 4.4 at ~13C. The beer is very clear and it does not seem to be getting worse in any way. It is possibly actually getting a little better. I will likely dump the 5 gal in kegs after botteling some and the let 5 gal in a secondary carboy stand for a bit longer.

That beer PH is pretty much on target.
