The beer known for reaching an extreme 75 percent alcohol by volume (ABV) is Beithir Fire, produced by Scotland's 88 Brewery. Surpassing traditional brewing thresholds, this specialty beverage combines a foundational Scottish barley ale with pure distilled spirits through innovative blending and filtration techniques. Because of its immense alcoholic strength, it is classified as a collector's item and is intended to be sipped in tiny measure quantities rather than consumed like a standard pint.
