If you ask me what is the characteristics of Vietnam, one way valve may tell you at first time that coffee is the most distinctive in Vietnam, and the most special is that you can easily to find a café and have a sit.
More than a century after the French brought coffee culture into Vietnam, the Vietnamese still retained an ancient way of drinking coffee – drip, a coffee brewing method that modern and romantic French could not wait, but it becomes into a classic and tradition by lazy Vietnamese. Sprinkle the ground coffee in "Phin (Traditional Vietnamese Coffee filters)" and after pressing balance of ground coffee, pour hot water in it, then patiently wait for it to drip a very dark and bitter cup of coffee at a slowly speed.
The creative Vietnamese pour thick condensed milk into the bottom of the cup, the strong sweetness of condensed milk mixed with the bitter taste of Robusta coffee, and this strong heavy taste seems to be the soul of the Vietnamese coffee. When you first time to sip the coffee, you may be a bit disappointed. But there are two kinds of fragrance in the coffee, and the interpretation of the brain is the same no matter smell or taste. The first taste is lavender, and the fragrance of lavender flowers remain in the mouth, but with a slight soapy smell; another taste is chocolate, it tastes as good as it smells.
In the streets of Vietnam even those who cannot name the cafe, always give travelers a surprise, it’s not only because you can use the price of a bottle of mineral water to drink a cup of good coffee, but also the owner brew again and again in daily life and get the experience. That’s probably the kindest and profound feeling of Vietnamese has coffee.
