Never tried to make a lager before. Making an all-grain Oktoberfest. Pitched with wyeast bohemian lager. Has been in primary at 54 deg for the past week. Didn't really notice a strong CO2 coming off the blow off. After 5 days, noticed what appeared to be true at the bottom, similar to my experience with ales. Pulled today and took gravity reading and it's the same as when I put it into primary, 1.064. Tasted beer and it's still sweet, without any noticeable sign of contamination. So I put the blow off back on, and put it back into the fridge at 54deg. So their than absolutely nothing happening the last week, any ideas on what's gone wrong? Appreciate your time.
