Thailand’s Best Beer? There’s a number of beers on offer in Thailand, and I’ve tested them all… here’s my advice…. stick with Singha and Leo. If you are a restaurant or 7-Eleven in Thailand and trying to decide which mainstream beer to choose… there are only a few choices and the majority are produced by Boonrawd Brewery. Boonrawd Brewery is so ubiquitous in Thailand that one ponders if this giant of a company may somehow have a impact on the very small and weak grass-roots, home-grown craft beer producers in Thailand. Compared with Vietnam…. where home-grown craft beer producers offer a great choice at a great price, Thailand doesn’t have much to offer and out-prices itself from being a viable option. So if you love craft-beer and in Thailand - you’ll be sad to hear that you may be forced to stare a refrigerator in a 7-Eleven or a restaurant and choose between Chang, Leo and Singha.
