I'm brewing an extract Barley Wine kit (from More Beer!), with Safale US-05 yeast. I know a lot of you much more experienced brewers follow a schedule of holding the temperature somewhat low for a few days and then increase it for a few days more before cold crashing. I set my fermenter at 65F at the outset--which is the ideal mid-point temp for this yeast--and have held it there for the past nine days with steady, though decreasing, airlock activity throughout this time. My Tilt hydrometer indicates that the SG continues to drop: from an initial reading of 1.087 to 1.024 this morning. If I'm still seeing airlock activity and the SG continues to drop, is there a reason to increase the temperature, or should I just let it ride at 65 degrees until the Tilt suggests fermentation has stopped? I don't have a glycol chiller, so cold crashing is not an option for me.
