Generally speaking, Myanmar culture (Burmese culture) means Buddhist culture, and is not identical with the modern geographical unity.
In terms of alcohol, many Burmese drink strong local moonshine-like drinks made from sugar cane. Myanmar Beer, Mandalay beer, Thai-produced Singha beer, Singapore-produced Tiger beer, cheap local beers, and cheap beers brought in from China are popular in Myanmar. Imported wines, whiskies, beers are expensive.
