Bia hơi, (hơi means gas, bia is from French bière, "beer"), is a type of draught beer popular in Vietnam.
Bia hơi are available throughout Vietnam. It is mostly to be found in small bars and on street corners. The beer is brewed daily, then matured for a short period and once ready each bar gets a fresh batch delivered every day in steel/metal barrels. It is a very light (~3% alcohol) refreshing lager at a fraction of the cost of draft or bottled beer in the Western-style bars. Bia hơi production is informal and not monitored by any health agency.
It is typically priced between 3000vnd and 7000vnd which is equivalent to 15 US cents to 35 US cents per 12oz bottle, making it a fraction of the price of any Western beer.
