Mash Notes |
1.5 level teaspoons Calcium Carbonate in roughly 4 gallons. Made no other adjustments. Really need water closer to 170 for mash-in. Mash was more like 150F for 20 minutes, then 154F for an hour. |
Boil Notes |
20 minutes from end, add 1/2tsp yeast nutrient, whirlfloc, hops & chiller. 1.056 pre-boil, overshot by a point. Added some Britta water. Wow, way overshot OG. Try less vigorous boil, and watch volumes. Maybe go back to collecting 8 gallons. |
