Vietnamese Coffee: From Highland Slope to Your Glass

Vietnamese coffee is not a mystery blend. It is, first of all, a plant, and the plant is mostly robusta. About 95 % of Vietnam's harvest is robusta, which makes the country the largest robusta producer in the world and, since the 1990s, the second-largest coffee producer overall, behind Brazil.

If your picture of coffee is a fruity, tea-like pour-over from a specialty roaster, adjust your expectations now. Robusta tastes of cocoa, toasted grain and bitter chocolate. It is sturdy, it carries roughly twice the caffeine of arabica (around 2.2–2.7 % against 1.2–1.5 %), and it stands up to milk and sugar like nothing else. The whole Vietnamese cup was built around those traits.

Most of it grows in Tây Nguyên, the Central Highlands: the provinces of Đắk Lắk, Lâm Đồng, Gia Lai and Đắk Nông. Đắk Lắk's capital, Buôn Ma Thuột, calls itself the coffee capital of Vietnam and you feel it. Coffee fields run right up to the edge of town.

The small share of arabica sits higher and cooler: Cầu Đất near Đà Lạt in Lâm Đồng, Sơn La in the north-west, and Khe Sanh in Quảng Trị. We dig into the differences, region by region, in Robusta vs Arabica: Inside Vietnam's Coffee Country.

Robusta cherries ripen from roughly October or November and the picking runs through January. Pickers work the rows with baskets, then the cherries are laid out to dry in sunny yards, raked over by hand until they are ready to be hulled.

Then comes the step that defines the Vietnamese cup: the roast.

Traditional Vietnamese roasting is dark, and often goes further than that. Beans may be roasted with butter or fat, sugar and flavourings, a style called rang bơ. The result is the chocolate and caramel character you taste in a good ca phe sua da, plus a deep, almost smoky bitterness that condensed milk is there to tame.

One word you will see on packs is culi: peaberry. Instead of two flat-faced beans per cherry, a culi cherry holds one small round bean. Many Vietnamese drinkers swear by it for a punchier cup.

The long version, with etiquette, vocabulary and the stories behind the stools, lives in Vietnamese Coffee Culture: History, Etiquette and How to Order.

The phin is a small steel drip filter that sits on top of your glass. You add ground coffee, press the insert on top, pour hot water, put the lid on and wait. No paper, no electricity, no pressure. Gravity does the work.

What comes out is concentrated, not quite espresso and not quite filter. It is also the reason Vietnamese coffee tastes the way it does: a long, slow extraction of a dark-roasted robusta.

The core recipe fits in one line: 20 g of medium-ground coffee, water at 90–96 °C, a 30-second bloom with 20 ml, then top up to about 80–100 ml and let it drip for 4–5 minutes.

Walk into any café and you will meet the same core cast. Learn these and you can order anywhere in the country.

• Cà phê sữa đá: phin coffee over ice with sweetened condensed milk. The default order, and the one most visitors fall for. 1–2 tablespoons of condensed milk go into the glass first.
• Cà phê đen đá: black iced coffee. Strong and bracing, usually with sugar.
• Bạc xỉu: lots of milk, a little coffee. It comes from Sài Gòn and the name is borrowed from Cantonese. The gentlest entry point.
• Cà phê trứng (egg coffee): a custard-like cloud of egg yolk and condensed milk on hot coffee. Recipe in Egg Coffee Recipe.
• Cà phê muối (salt coffee): from Huế, popular since around the 2010s. A salty-sweet cream on top of the coffee.
• Cà phê cốt dừa (coconut coffee): coconut slush with coffee, popularised by Cộng Cà Phê, founded in Hà Nội in 2007.

You do not need a barista course. You need three things: a phin, a robusta-heavy dark roast, and condensed milk. A hand grinder helps if you buy whole beans.
