Sparge is distilled.
Reserved and excluded baking soda as measured PH was 6.0 before roasted malts added.

Ph must be in 5.4 to 5.6 range for this style.

Added .5mL of Lactic acid to mash. Could have added more but I've doubts on the PH meter. On mash out, recalibrated teh meter and Ph was bang on 5.5 - 5.6

Notes


This version uses flaked oats and victory to build character.

Lactic acid to mash if needed to balance PH. Last batch required a small addition. Consider adding some Acidulated Malt instead.


First brew added .6ml lactic to mash due to high PH. Plus 5ml lactic to sparge. worked out very well with no acid tastes in the brew.

For next I have added acidulated malt to mash to replace its need for Lactic acid adjustment.
