I have a Hefeweizen fermenting that seems to have stalled out on me. I did a triple decoction with rests at 130, 145, 157, and 169. My OG was 1.052. I put in my tilt which read the OG as 1.048, it always seems to read a little lower than my hydrometer for some reason. One pure pitch pouch of WLP300 with no starter. Open fermentation for the first 24 hours and then put the lid on. Temp started at 62 and was allowed to rise to 69/70. I made this beer Monday so it hasn’t even been 48 hours (I know I know) but airlock activity has stopped and my tilt has been stuck reading 1.022 since airlock activity stopped. What do you think?
