I have brewed two 5 gal all grain batches of the Dogfish 60 IPA clone with an OG of 1.068-1.070 using WLP001 with a 1 liter starter at 67* and good temp control. Both times the 3ft long 1" blow off tube has done the trick, but I wound up with a 1/4" to 1/2" of yeast in the bottom of the blow off container filled with starsan. Seems a little much. Am I looking at off flavors or other issues from this almost explosive fermentation?
