Indeed it isn't a beer. It's 40% so it's probably going to cost anywhere between
£10-50 per bottle, which for a specialised spirit/liquor isn't too bad....
At that ABV it's going to be sipped and savoured and should provide many
days/nights of enjoyment.
When you compare the cost to one bottle of super-dooper barrel aged beer
which could easily be the same cost it is actually pretty cheap!!! That's
because barrel aged beer is mainly silly money.
