The Bottle label claims an abv of 67.5%.
"Snake Venom is the world’s strongest beer as of 24 October 2013, coming in at 67.5%. It is dark amber in colour with no carbonation due to the high ABV.
Unlike the previous Armageddon, the alcohol is not masked in Snake Venom. It is highly present yet it still tastes like a beer with a good degree of hop profile.
Each batch is tested by the brewery before bottling and random batches are tested externally."
Marked unrateable due to an admission by the brewer of correcting ABV with pure alcohol.
