It's called Snake Venom, and it contains a massive 67.5% alcohol by volume. (Vodka, in comparison, is typically 80 proof, or 40% alcohol). The brewery decided to manufacture an even stronger beer after some customers complained its first attempt was too weak, Scotland's Daily Record reported.
Brewers Lewis Shand and John McKenzie said they didn't want Armageddon, now the world's second-strongest beer, to have an overwhelming taste, so they made it oily. This time around, they didn't try to disguise the sharp taste of the alcohol in Snake Venom. It's so strong the beer comes with a yellow health warning stuck to the bottle's neck.
