4.
The name given to wine, generally white, when removed from the cask. The sack is made of a strong foil, so it can be passed around without getting damaged.
It is a popular alcohol choice for Australian teenagers, as it costs no more than $15 for 4 litres, which is a very affordable way to get fucked up.
When one is intoxicated, they often drink the juice straight from the sack, although it is also commonly mixed with other liquids such as orange juice or soft drink, to make the taste more tolerable.
