Rượu sim

Rượu sim is a traditional rose myrtle liqueur that hails from Phú Quốc. It is usually made with a combination of rose myrtle berries (Rhodomyrtus tomentosa), sugar, and rice wine. Rose myrtle grows wild in the mountainous regions of Phú Quốc, and the berries are usually harvested in spring.

The drink originated in rural areas and is traditionally promoted as a health remedy. It can be produced by fermenting berries and sugar or steeping berries and sugar in rice wine for several months. The result is a fragrant red liqueur with a distinctive sweet and tart flavor.

There are several available styles, which may differ in character and alcohol content. Commercially produced varieties are also available.
