Alcohol in Mongolia The first day of each month is forbidden to sell alcohol because it is belived that at least one day should be sober. In addition alcohol has an extra tax of 1% to demotivating its selling, even so, it is really cheap. A 500cc can of beer, in 2018, cost an average of 0,7 USD and one bottle of 2 litres only 2,3 USD The best thing is the quality is still good even in the most economical one and unlike Chile, buying beer in glass bottles is cheaper than cans.
