Just a follow up. My bock finished at pH = 4.74 cf typically 4.4 so way above normal. I added (dissolved) 4g CaCl2 and pH dropped to 4.63. Then I added 2mL 88% lactic and pH went down to 4.57. Still high but acceptable for a malty beer so I stopped mucking around with it. The taste is good end...

Thanks for your reply. Yes, according to the label it is 96% phosphoric acid. I double checked before posting. I guess we buy from different suppliers but a few % won't make any difference in the scheme of things. The other area of concern for me was loss of calcium through precipitation of...

Silly me accidentally spilled about 10ml phosphoric acid (96%) into boiling wort when doing pH adjustment for a dunkle bock. pH dropped to 4.7 and stayed there but after adding NaOH I eventually got the pH back up to 5.1. Water treatment has the water salt profile prior to the accident at about...
