3/20/2018 3:01 PM over 6 years ago	-1	Yeast Starter	1.040	1.4 Liters	2/20/2021 3:43 AM over 3 years ago	Yeast starter placed on stirrer in Fermentarium 48-hours ahead of Brewday.
3/21/2018 9:52 PM over 6 years ago	+0	Brew Day Complete	1.040	44 Liters	2/20/2021 3:43 AM over 3 years ago	Some issues with chilling that needed mid-chill change of plate chillers, not good. Left the post chill wort to settle for 45 mins which was a major success for the clarity of the transfer. Left 3-4 litres of shit and trub in bottom of kettle
3/27/2018 5:00 PM over 6 years ago	+6	Sample	1.008		2/20/2021 3:43 AM over 3 years ago	Still bubbling at 2 or 3 bubbles per second, so probably a few days away from terminal gravity
4/12/2018 6:20 PM over 6 years ago	+22	Fermentation Complete	1.006		2/20/2021 3:43 AM over 3 years ago
4/12/2018 6:22 PM over 6 years ago	+22	Packaged		38 Liters	2/20/2021 3:43 AM over 3 years ago	2x full cornies collected. Will 'lager' in the fridge at 1-3oC for 1 month.
5/3/2018 9:40 AM over 6 years ago	+43	Tasting Note			2/20/2021 3:43 AM over 3 years ago	First taste after 4 weeks of conditioning. Excellent flavour, subtle malt and bitterness with no off flavours - requires a little further settling for clarification purposes.
5/9/2018 2:00 PM over 6 years ago	+49	Other			2/20/2021 3:43 AM over 3 years ago	Flavour good as reported yesterday - however probably needs a little more CO2 as keezer is only set to 12psi for the ales. Separate feed added to further charge the Kölsch to 18psi
5/9/2018 2:02 PM over 6 years ago	+49	Tasting Note			2/20/2021 3:43 AM over 3 years ago	After 5 days at 18psi at 2oC - the carbonation level is now spot on. Refreshing, clean Kölsch flavour
