Notes

Brew a 25L batch and then dilute 8L to 10L and pitch WLP830 German lager and 16L to 20L and pitch WLP001.

Brewed Tuesday 3rd March 2015. 25.5L at 1.078 (75% efficiency).

16.5L diluted to 20.7L (1.062) and 1L WLP001 starter pitched at 18oC.
9.5L diluted to 12L (1.062) and WLP830 1L decanted starter added the next morning when wort had reached 8.5oC.

Calcium Sulphate (Gypsum): 1g to strike water and 1g to the sparge water
Espsom salts: 1g to strike water and 1g to the sparge water
Calcium Chloride 3g added to the strike and sparge waters as 33% solution (not as dihydrate) so scaling / correction factor = 110.98 g/mol (anhydrous) / 147.014 g/mol (dihydrate) * 3 = 2.26. 1.5g x 2.26 = 6.8 mL.
Baking Soda: 1g to strike water and 1g to the sparge water.
No Lactic acid as want to leave bicarbonate in the water.

09/03/15 (Mon) Day 7 - Ale porter SG = 1.022. Moved to pan room at 21oC (still some krausen on beer).

15/03/15 (Sun) Day 13 - Lager porter SG = 1.023...

24/03/15 (Tues) Day 22 - Lager SG = 1.019, Ale SG = 1.019. Lager moved to the attic and both beers dry hopped. Ale = 19g Simcoe + 24g Nelson Sauvin. Lager = 9g Simcoe + 10g Nelson Sauvin. So only about 2g/L per beer...

27/03/15 (Fri) Day 25 - Both beers moved to the attic to "cold crash". Not really cold enough...
