Ca phe sua da or cafe sua da (Vietnamese: cà phê sữa đá) is a unique Vietnamese coffee recipe. Literally, ca phe sua da means "coffee milk ice". Ca phe sua da can be made simply by mixing black coffee (typically a dark French roast, often with chicory) with about a quarter to a half as much sweetened condensed milk and then pouring it over ice. The coffee is traditionally brewed with a small drip filter into a cup containing the condensed milk. The condensed milk and coffee are stirred together and then poured over the ice. Ca phe sua nong (Vietnamese: 'cà phê sữa nóng') - literally, "coffe milk hot" - is made by excluding the ice.
pretty sure that will have less caffeine by volume at least than an espresso. with a proper espresso, you have about 9 BAR of pressure forcing nearly boiling water through fine coffee grounds. so 10x as strong sounds embellished..
sorry, can't bash the sacred espresso.
