Notes
Add 1.5g baking soda, 0.4g gypsum.
Bring water to 75C, steep specialty malts for 30 mins. Forgot to turn off the heat (lowest flame), when remove lid bring up to boil only used 2mins (water raise from 75C to appox. 88C in these 30 mins?)
Bring to boil, add 6g sorachi-ace and boil for 15mins, then flame out and add malt extract (1kg LME) - used 15 mins for adding the LME as found initial extract have mold.
Bring to boil again, and top up water to 4L. Add 2g sorachi ace and boil for 5 mins, flame out. Cool down wort to 80C and add 6g Nelson Sauvin, hop stand for 10 mins. wort temp drop to 65C in 10 mins. Cool down wort to 23C, pitch 5g dry yeast.
Refractometer reading 1.076, 0.011pt lower than expected, may due to haven't done enough sparging for the steeping malt.
Ferment in room temp (20C)
Priming 2.0 vol CO2 - since I only bottle 1 (500ml), added 1.8g sugar for priming. 1.1g for second bottle (375ml)
Other 2L goes in force carbonation - 8g Co2 cartridge in 15 psi, chill in 5C. After 72 hours noticed that the psi gone up to 20 psi. Close the gas gauge and let it chill for 72 hours more. When open notice no Co2 and no foam, maybe due to no shaking the beer in the process. Replace a new 8g Co2 cartridge and give it a shake 2-3 times a day. After 48 hours served with beautiful foam - Shaking is very important!
Clear flavor profile, some acetyldehyde (green apple), toasted coffee cocoa, some hints of chocolate. Can serve as a good base to add some more ingredients e.g. peanut butter, cocoa nibs, vanilla, etc.
