I'm doing my first lager and I am following the directions of the LHB shop guy. He said that once fementation is 75% complete, raise the temp to 70deg and hold it there for 3 days...then rack to secondary and reduce temp by 3deg per day down to 35 and lager at 35deg for 60 days.
After 7 days at 49deg I took a SG reading and it was 1.020 which is what I calculated it would be at 75% complete. There was still a lot of airlock activity (about 1 bubble every 2 seconds) but I did as instructed and brought it up to 70 deg. That was 24 hours ago. There is still a lot of airlock activity.
I did a search on HBT and found most people recomend waiting until visible fermentation is complete and then doing only a 24-48 hour diacetyl rest before racking to secondary and lagering.
Have I made a mistake? Should I cool it back down to 49 and wait until airlock activity stops and then do another diacetyl rest? Or should I just let it finish fermenting at 70 deg and then rack it to the secondary?
