Judging by the badly-attached sticker and the odd sediment at the bottom of the bottle, this vodka is home-made.
― In-game description
The Cossacks 2 vodka is a mission item in S.T.A.L.K.E.R.: Clear Sky.
Description[]
This item is part of a side mission given by Bandits squad leaders in the Garbage. The leader who gives the job states that "it's not the crap everyone's drinking". The vodka can be found in a pipe just north to the Bandits base, beside a Electro anomaly.
The player cannot drink this vodka, much like the "Magic" vodka, and it only serves as a mission item.
