Water treatment to the entire water volume (full volume mash)
Calcium Sulphate (Gypsum): 6.5 g
Calcium Chloride 2g (not as dihydrate) so scaling / correction factor = 110.98 g/mol (anhydrous) / 147.014 g/mol (dihydrate) * 3 = 2.26. 2 x 2.26 = 4.5 mL.
Lactic Acid (80%): Calculated as 4.1 mL, but added 2/3 of the calculated value to the mash (2.8 mL).
pH = 5.4 and no further lactic acid required. |

Notes
Recipe changes:
Maris Otter subbed for American 2-row
Columbus used for bittering instead of Magnum
Galaxy used in the whirlpool instead of Cascade
WY1318 used instead of Chico yeast.
Friday 8th January 2016 - 1.6 L starter onto stirplate. WY1318 captured from blow off of last batch (6th generation).
Sunday 10th January 2016 - Added starter to keezer to settle yeast (decanted off 0.5 L for future use).
Sunday 10th January 2016 - Brewday. Heated 29L strike water to 69oC. Mashed in at 15:50. Mash temp = 64.5oC. Aiming for mash pH of 5.4 (adjusted with gypsum, CaCl2 and 80% lactic acid). Added 2/3 of lactic acid before mashing in.
Calibrated pH meter (had drifted by +0.06). Tap water pH = 7.75.
15 mins. Stirred the mash. Mash temp = 63.8oC. Mash pH = 5.45.
30 mins. Stirred the mash. Mash temp = 63oC. Mash pH = 5.40.
45 mins. Stirred the mash. Mash temp = 62.2oC. Turned on the induction plate. Mash pH = 5.41.
60 mins. Stirred the mash. Mash temp 63.7oC. pH = 5.40.
"Sparged" by pouring 4L of 55oC water (no water adjustment) over the grain bag whilst it drained and squeezing the bag.
Approx 28.5L of wort collected from the mash. Preboil gravity = 1.052.
Whirlpool 1. Cooled wort to 80oC and transferred 13L to a sanitised plastic bucket. Added hops to the kettle at 77oC. 69oC after 10 mins. 63oC after 30 mins. Stirred every 5-10 mins.
Whirlpool 2. Chilled in bucket to 51oC and added hops at 49oC. After 15 mins = 45oC. Stirred every 5-10 mins.
Chilled both batches using immersion chiller to about 30oC and then transferred to PET carboys. Left outside at -2oC (covered with foil) to reach pitching temp. Split the starter between each carboy (pitched at 18oC).
OG = 1.058. Post boil pH = 5.3. Each batch approx 12L.
Saturday 16th January (Day 7) - Crash chilled in fermentation fridge at -1oC. Ferm temp has been low on this one as fridge was busy with a lager so these beers were fermented at an ambient 15oC in our basement storage room.
Sunday 17th January 2017 (Day 8) - Kegged with gelatine (carboy to liquid outpost siphon into oxygen purged kegs). FG = 1.016. ABV = 5.5%.
