Im sure im going to get alot of dont worry replies but Im very curious if this is normal or a sign of something wrong. This is my first lager.
Its a 8.4 est ABV oktoberfest using Saflager s-23. I rehydrated yeast in wort cooled to 55 deg. for about 2 hours prior to pitching. I cooled wort to 58 deg , aerated with pure o2 for 40 secs. pitched the 55 deg yeast and put in 52 deg fridge for fermentation. After about 2 days I noticed airlock activity. Its been very steady at around 12 bpm (1 every 5 secs) . 2 weeks later its at around 8 bpm ( 1 every 8 - 10 secs ) . The only brew ive seen go this long was my barleywine. Im assuming it take longer due to the higher amount of sugars for the yeast to eat.
Is it normal for a lager to still be so active after 2 weeks? Is it due to it being a higher ABV brew? my barleywine was 12.6 , this is 8.4 which is high for a oktoberfest but nothing spectacular. Maybe a combo of 8.4 and slower lager yeast at low temps? Most of what ive read people say there lagers take 7-10 days before airlock activity dies down.
