So i brewed my first lager last week and i'm not sure if everything is on track. It was an oktoberfest and my yeast was wlp820. My OG was 1.061. I pitched at about 50 degrees and fermented around 54. At five days in my gravity was 1.030 so i raised the temp to 61 for a d-rest. Today my gravity is at 1.019 which is my predicted FG. The sample did not taste all that great so i was going to lower the temperature to back around 54 and leave for a couple weeks. Does this sound right or should i start lagering now? Could the d-rest cause an off flavor?
