Bia hơi is available primarily in northern 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 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 5,000VND and 12,000VND for a small cup of about 100-150mL (as of March 2020).
