This:
Is not a worthwhile double blind, as there was no control group. A double blind test would have to either have a control group comparing two un-oated beers, or have to have 3 glasses (1 from one group, 2 from the other) to test to see if one can identify a difference when there is none to be identified. On top of all that, you would have to do this individually, without discussion for there to be any merit to this experiment.
Do you conduct a double blind experiment every time you make a change in your process to make sure that it's worth doing?
