Hi all,
Recently I decided to brew up my first real lager with a tin and some extracts, hops etc, etc. I have good temperature controll with my new brewing fridge set at 12'C ready to go. After 1 week my air lock has slowed down considerably and after checking my gravity reading several times over the last couple of days I have a steady reading of 1.020.
After reading some posts on AHB I have found some brewers use 2 packets of yeast in order to maintain 1.010 final gravity. I am using Saflager S-23 and only pitched 1 packet with my wort at 22'C. After waiting 12 hrs my airlock was starting to discharge Co2 so I placed the fermentor into the fridge and chilled it down to 12'C after 24 hrs.
I understand lagers can take a longer period of time to ferment due to lower temperature conditions. With S-23 at 12'C how long should a normal fermentation period last? I started of with a gravity of 1.040 and after 8 days im at 1.020. Is brewing at lower temperatures with lager yeast a slow process in comparison to ale brewing with Safale US-05 at 20'C with around the same gravity of 1.040. Most ales i have done with US-05 maintain airlock movement untill 1.010 or 2 weeks in primary.
