Vietnamese Iced Coffee

Ca phe sua da (literally "coffee milk ice") is Vietnam's signature coffee drink and one of the most distinctive coffee preparations in the world. It is made by brewing strong, dark roast robusta coffee through a small metal drip filter called a phin, directly over a generous layer of sweetened condensed milk. Once the coffee has finished dripping — a slow, meditative process that takes four to six minutes — the thick, dark coffee and the sweet, creamy condensed milk are stirred together and poured over a tall glass of ice.

The result is a drink that is simultaneously bold and sweet, bitter and creamy, strong and refreshing. Unlike most iced coffees that dilute and weaken as the ice melts, Vietnamese iced coffee is brewed so concentrated that it maintains its intensity even as it chills. The combination of robusta's natural bitterness with condensed milk's caramel sweetness creates a flavour profile that is entirely unique — rich, chocolatey, and deeply satisfying.

Vietnamese coffee culture is deeply social. In Vietnam, coffee shops are gathering places where people spend hours talking, reading, or simply watching the world go by over a single glass of ca phe sua da. The slow drip of the phin filter is part of the ritual — it forces you to slow down, wait, and savour the anticipation. At Pho By Night in Ottawa's ByWard Market, we bring this tradition to every glass we serve.

Vietnamese coffee stands apart from virtually every other coffee tradition in the world, and the differences go far deeper than just the filter. It begins with the beans. While most speciality coffee cultures prize arabica beans for their delicate, nuanced flavours, Vietnam built its entire coffee industry on robusta — a hardier species with nearly double the caffeine content, a bolder flavour, and a more intense bitterness. Vietnam is the world's largest producer of robusta, and this bean defines the country's coffee identity.

The choice of robusta was not accidental. When the French brought coffee cultivation to Vietnam in the 1850s, the country's climate and terrain proved ideal for robusta rather than arabica. Vietnamese farmers and coffee drinkers embraced the bean's strength and adapted their preparation methods to complement it. The phin filter's slow extraction softens robusta's harsh edges, while sweetened condensed milk — introduced because fresh dairy was scarce and expensive in tropical Vietnam — balances the bitterness with rich, caramel-like sweetness.

The French colonial influence is unmistakable. The tradition of long, leisurely coffee drinking, the cafe culture, even the use of condensed milk (a French invention by Nicolas Appert) all trace back to the colonial era. But Vietnam transformed these European influences into something entirely its own — a coffee culture that is simultaneously bold, patient, and deeply social. The phin filter forces you to wait for your coffee, turning every cup into a small ritual of anticipation.

Today, Vietnamese coffee has inspired a global movement. From specialty ca phe sua da shops in Los Angeles and New York to Vietnamese coffee chains expanding across Asia, the world is discovering what Vietnam has known for over a century: that coffee does not have to be subtle to be extraordinary. At Pho By Night, we are proud to serve this tradition in Ottawa's ByWard Market — authentic phin-brewed Vietnamese coffee, just as it should be.

At Pho By Night, Vietnamese coffee is not an afterthought — it is an essential part of the dining experience. We serve authentic ca phe sua da brewed using traditional phin filters with dark roast robusta beans. Every glass is prepared fresh and served exactly as it would be in a Vietnamese coffee shop: with the phin still dripping over a bed of condensed milk, so you can watch the brewing process and stir it yourself when it is ready.

Our Vietnamese iced coffee is the perfect complement to any meal on our menu. Many of our regular customers order it alongside a bowl of pho, a banh mi sandwich, or a vermicelli bowl. The bold sweetness of the coffee provides a refreshing contrast to the savoury, herbaceous flavours of Vietnamese cuisine.

We also serve ca phe den da (black Vietnamese iced coffee) for those who prefer the pure, uncut intensity of robusta without condensed milk. Whether you choose sweet or black, hot or iced, our Vietnamese coffee is brewed with the same care and authenticity that has defined Pho By Night for 26 years. Visit us at 309 Dalhousie St in Ottawa's ByWard Market and experience Vietnamese coffee culture firsthand.

Coffee arrived in Vietnam in 1857, brought by French Catholic missionaries who established the first plantations in the central highlands. The French initially attempted to grow arabica, but the tropical lowland climate proved better suited to robusta — a species that thrives in heat, resists disease, and produces abundantly. By the early 20th century, coffee was firmly established as a Vietnamese crop, and the country's relationship with the bean had begun its unique evolution.

During the French colonial period, cafe culture took root in Vietnamese cities, particularly in Hanoi and Saigon. The French-style sidewalk cafe became a fixture of urban Vietnamese life, but the coffee itself was distinctly Vietnamese — strong robusta brewed slowly through metal filters, sweetened with condensed milk because fresh dairy was impractical in the tropical climate. It was during this era that the phin filter became the standard Vietnamese brewing method, and sweetened condensed milk became coffee's inseparable companion.

In 1946, during a period when fresh milk was especially scarce in wartime Hanoi, a bartender named Nguyen Van Giang created ca phe trung — egg coffee. He whipped egg yolk with condensed milk and sugar to create a thick, custard-like foam that he layered over strong black coffee. His cafe, Giang Cafe, still operates in Hanoi today, and egg coffee has become one of the city's most iconic beverages.

After reunification in 1975, Vietnam's coffee industry entered a period of transformation. The government invested heavily in coffee production, and by the 1990s, Vietnam had become the world's second-largest coffee producer — a position it still holds today. The country produces over 1.5 million tonnes of coffee annually, the vast majority of it robusta. This enormous production capacity has made Vietnamese coffee not just a domestic tradition but a global commodity.

Today, Vietnamese coffee culture is experiencing a renaissance both at home and abroad. In Vietnam, modern coffee chains like Highlands Coffee and The Coffee House coexist alongside traditional sidewalk cafes where elderly men still spend entire mornings over a single glass of ca phe den. Internationally, Vietnamese iced coffee has become a fixture of specialty coffee menus from New York to London to Melbourne. The world has discovered what Vietnamese people have known for generations: that boldness and sweetness, patience and intensity, can create something extraordinary in a glass.
