Notes

Brewday 18.01.2015.
Mashin at just above 60deg, temp drop to 54-55deg. Let rest for 15min. Add boiling water to reach 65deg, ca 7-8liters.
Let rest for 20mins.
Add 4liters of boiling water to reach 70deg. Let rest for 20.
Have 10-15 liters of sparge water at 75.
Sparge to collect 24liters of wort @ ~1060.

IBU Calculations have to be done separately since boil gravity will be ca 1060. Dry malt extract added last 15 mins of boil.



Pitched yeast at 20deg, cooled to 18during first night and let rise to 19during first day. Keep at 19 till end of primary.

ca 22l into fermentor @ 1103

Fermented at 18.5-19.5deg C.
Gravity ca 1034 after 10days.

08.02.2015
Racked to keg with a pack of CBC-1 yeast. Gravity @ 1033
Will try to referment it to get below 1030.

15.02.2015
Sample from keg after 1 week is 1031.

29.03.2015
Racked off yeast. FG is 1030.
Abv 9,5%-9,6%
