a month ago, my boss gave me a packet of coffee, i was so happy and rush to try, i put 1 big spoon coffee in a pot, then i put a glass of hot water, then i taste it, urh! so terrible, just like water no coffee taste at all.
a week ago, i went to a cafe and order a Vietnamese coffee, just like the photo, i look in side the brewer and realize i need to put the coffee and water 1:1, like 1 teaspoon coffee with 1 teaspoon water. Wow!!! the taste very good. I think I am outdated.
