Vietnam is known for having super strong coffee. Here in Vietnam they primarily grow Robusta coffee as opposed to Arabica which is more common is all western countries. The Robusta coffee has almost double the caffeine of Arabica and has a darker, more bitter flavor. Many people will drink it with condensed milk for a sweeter flavor. (cà phê sữa) Other popular options: black coffee with no sugar (cà phê đen không dường) egg coffee (cà phê trứng) coconut coffee (cà phê cốt dừa) Salt coffee (cà phê muối) I was never a big coffee drinker before I moved to Vietnam, now I can't live without 2 cups a day. I wonder if I'm going overboard or if I have any more coffee fiends out there?!
