Here's where to get the cheapest beer in the world

Head to Slovakia if you want cheap beer.

According to the newly released Beer Price Index, which collected prices on beers from supermarkets and bars in 70 cities around the world, Bratislava ranks as the cheapest place to buy a cold one.

The BPI is the end result of extensive data collection from the travel site GoEuro, which puts together price indexes on common goods tourists like to buy.

Researchers at the company visited three supermarkets and three hotels in each of the cities they visited, combining the costs for each, standardizing the quantity of alcohol, and converting the end number into a single currency.

New York, unsurprisingly, ranks near the expensive end of the world's beer-loving cities at $5.36 a pop. Although, its beer was still found to be cheaper than eight other cities.

Lausanne, Switzerland came in as the most expensive, with an average price of $9.51 per bottle.

These price differences are partly reflected in consumption levels. New York's annual per capita consumption of four gallons pales in comparison with that of both Bratislava (18 gallons) and Kiev (27 gallons), but it still drowns out Cairo, which consumes just one gallon on average.
