My freezing point is that what is the difference between a whisky and a ‘sink the bismark’type beer. A barley wine is a barley wine, so how can something stronger be called a beer?
Barley wine is a beer style like Stout or IPA, not a strength classification. The name was coined because it can be as strong as a wine, but it’s technically a beer due to ingedients, barley, hops, yeast, water. The style guidlines for Barley wine mean that most of them are around 8/9%. Plenty of IPA’s, Porters, Stouts at 8% and above but not called barley wine. But they’re all beers.
Same goes for STB, it’s brewed from barley, hops, yeast, water. It’s fermented using yeast, rather than distilled as a spirit is. So it’s a beer.
It’s a crazy strong beer, and should be treated like a spirit as a result. Brewdog themselves say this. It’s served in spirit measures in their bars, and should be enjoyed like a fine malt. But it’s still a beer.
