My first Hefe, brewed last June with this yeast had quite a lot of banana flavors. It was the middle of the summer, with a bucket and bottles of ice I kept the temp at the high end of the strain, around 70 degrees.
I have a second batch fermenting now, and have kept the temp on the lower side - 60-64 degrees - for a week. Airlock activity has been steady but not vigorous enough to require a blow-off tube. I am now a bit concerned that it will not finish as completely as I would like it to.
I have not taken a gravity reading yet since the original (1.060).
Should I increase the temperature for a few days to encourage a bit more activity?
