Roughly translating into “fresh beer”, Bia Hoi is brewed daily and has to be drunk within 24 hours as it contains no preservatives and therefore spoils quickly: even more of an excuse to have a glass (or three!) in the evenings.
The purity is not the only unique thing about Bia Hoi though, it also has a rice content of up to 50% depending on the brewer. This gives the boozy nectar its golden colour and light, draught taste; a recipe which was stolen by mainstream Budweiser – or so claimed the Vietnamese man who served me in Hanoi.
In a classic Vietnamese way, this bargain beer is delivered across the city streets from the back of motorcycles. You can usually tell when they’re coming as local customers will often wait for their preferred beer bike to deliver their favourite tipple.
