Add 3ml Lactic acid to each G70.
G702 mash start 0855. G701 mash start 0900.
G702 pH 5.6. add 2ml Lactic acid, G701 pH5.7 add 2ml lactic acid. Next readings g
G702 5.5 and G701 5.4.
G701 collect 65.5L, G702 collect 65L.
Both boiling at 1115.
Then it all went pear shaped when one counter cooling coil blew up....
G702 56.25L after boil G701 forgot to check probably similar so say two at 56 = 112L less 6L ( 3 each G70 ) left in G70's do 105-106 into fermenter - top up with 5.5L filtered water.
