Glad you liked to interview. It seemed to go well from where I was sitting anyway.
They were definitely looking for someone to be outraged by this. When I was talking to the researcher yesterday she was actually surprised when I defend brewdog. She thought I was just going to jump on the "less of that now!" band wagon and try to add that we're not all that bad.
The outrage is actually all part of the same alcohol culture as binge drinking. The only reason people would be bothered by the concept of a high alcohol beer is if they see beer as nothing more than a means to an end. If pints of the stuff to get drunk is your only experience of beer then this would seem like a very bad idea indeed, but it requires a very narrow and unhealthy attitude to alcohol.
People with a healthy attitude to alcohol would not see this as a problem, because they drink a sensible amount of alcohol, regardless of how strong the beverage is.
