Notes

Based on the recipe for Societe brewings the Pupil IPA (tweaked the hops a little)
http://meekbrewingco.blogspot.ca/2014/05/brewing-societe-brewing-pupil-clone.html

Brew a 25L batch and then split into 2 fermentors. Dilute back to 1.062 so that one batch (16.6L) is 20L (1.6L WLP001 starter) and the other batch (8.4L) is 10L (1 vial funktown pale).

Brewed Sunday 1st March

18.5L strike water at 72.5oC gave a mash temp of 64.5. Stirred the mash after 20 mins (temp was 64).

Sparged with a little extra water for yeast starters. Approx 30L preboil vol and then topped up after 20 mins. Ended up boiling longer (90 mins). Preboil gravity 1.058.

Added sugar with 10 mins remaining in the boil.

Ended up short of target gravity. 24L at 1.065 diluted to 27L at 1.058. 18L WLP001. 9L conan/brett

Aim for mash pH of 5.4 (predicted) using:
Calcium Sulphate (Gypsum): 3g to strike water and 3g to the sparge water
Espsom salts: 2g to strike water and 2g to the sparge water
Calcium Chloride 1.5g 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 = 3.4 mL.
Lactic Acid (88%): 6.9 mL added to strike water and 1.6 mL added to sparge water (to acidify to pH 5.4).

05/03/15 (Thursday) Day 5 - Beers moved from 17oC ambient "storage" to 21oC ambient "pan room".

06/03/15 (Friday) Day 6 - Funktown Pale (Brett IPA) = 1.016.

09/03/15 (Monday) Day 9 - WLP001 (IPA) = 1.009.

15/03/15 (Sunday) Day 15 - Dry hop 1 14g Mosaic + 14g Citra + 28g Nelson for IPA. 7g Mosaic + 7g Citra + 14g Nelson for Brett IPA.

19/03/15 (Thursday) Day 19 - Dry hop 2 added. Equal amounts.

22/03/15 (Sunday) Day 22 - Moved to attic to crash chill (~8oC ambient temp)

24/03/15 - Tuesday Day 24 - Kegged both beers without gelatine. Attic temp 12oC. Hooked up CO2 at 2.2 bar.
