Primary Temperature: 68 degrees F

Original Gravity: 1.053 SG 13.10 Plato

Mash Notes
Trying a dilution of the DC tap water: mash with 3 gallons distilled plus 2 gallons tap, plus a little over a teaspoon of CaCl2, the remaining water in the session being DC tap. At mashout the infusion ratio was 1.8 qts per pound so the manifold found the bottom pretty easily. I sparged with 3 gallons and collected about 8 gallons into two pots. Next time much more volume.

Fermentation Notes
Should have made a larger batch, maybe 8.5 gallons

Added about 16 ml of 88% lactic acid during primary fermentation.
