What Is a Flat Black? The Black Coffee With a Borrowed Name
Share
What is a flat black? It is an informal café name, not a standardized drink. Where you see it, it almost always means a short, strong black coffee made from espresso and a modest amount of hot water, served in a small cup like a flat white but with no milk. The name is a play on the flat white, the Australian and New Zealand milk drink, and you will usually get something very close to a long black or a short Americano.
Because there is no official recipe, this guide explains what to expect, how the flat black sits beside its better-documented cousins and how to make a great version at home.
What is a flat black, and where does the name come from?
The flat white is an espresso drink with steamed milk, with more coffee relative to milk than a latte and a thinner layer of microfoam than a cappuccino. Both Australia and New Zealand claim it; one documented Australian reference is Alan Preston adding it to the menu at Moors Espresso Bar in Sydney in 1985, while New Zealand stories point to cafés in Auckland and Wellington. In Australia it is typically served in a roughly 200 ml cup, and in New Zealand in a roughly 175 ml cup.
Black coffee lovers simply borrowed the format. Swap “white” for “black,” leave out the milk, and you have a flat black: the same cup size and coffee strength, built with water instead. You will not find the term in coffee standards or most encyclopedias, so treat it as café slang. For a full breakdown of the milk drinks, see our guide to latte vs cappuccino vs flat white.
Flat black vs long black, Americano and espresso
| Drink | How it is built | Typical espresso | Water | Taste |
|---|---|---|---|---|
| Espresso (short black) | Espresso only | Single or double | None | Most intense |
| Flat black (informal) | Espresso with a small amount of hot water, small cup | Usually double | Modest; café dependent | Strong, slightly softened |
| Long black | Double espresso poured onto hot water | Double | About 100–120 ml | Strong, pronounced crema |
| Americano | Hot water poured onto espresso | Often single | More than a long black | Milder, longer |
The long black is the closest documented drink. It is popular in Australia and New Zealand, where it was introduced in the 1950s and 1960s, and it is made by pouring a double espresso into hot water, which keeps more crema on top. An Americano reverses the order and usually uses more water. We cover that pair in detail in Americano vs long black, so here we will focus on what makes a flat black different: the small cup and short, punchy ratio.
How to order a flat black (and get what you expect)
Because the term varies, a quick clarification saves disappointment:
- Ask what it means at that café. Some use it for a long black in a small cup, others for a double ristretto with a splash of water.
- Name the size. “A double shot in a small cup, topped with a little hot water” is universally understood.
- If it is not on the menu, order a long black and ask for less water, or a short Americano.
How to make a flat black at home
Makes: 1 small cup (about 5–6 oz / 150–175 ml)
| Ingredient | US | Metric |
|---|---|---|
| Freshly ground coffee (espresso grind) | about 1 1/4 tbsp, weighed | 18 g |
| Double espresso yield | about 1 1/4 fl oz | 36–40 g |
| Hot water, about 195°F | 3–4 fl oz | 90–120 ml |
- Warm the cup. A small ceramic cup, around 6 oz, keeps the drink hot and gives the right look.
- Add the water first. Pour in 3–4 fl oz (90–120 ml) of water just off the boil, around 195°F (90°C). Water first protects the crema.
- Pull the double shot on top. Brew straight onto the water, aiming for about 36–40 g of espresso in 25–30 seconds.
- Taste and adjust. Too strong? Add a splash more water. Too thin? Next time use less water or pull a ristretto.
No espresso machine? Use 2 fl oz (60 ml) of strong moka pot or AeroPress coffee instead of espresso and reduce the water to about 2–3 fl oz (60–90 ml).
Ristretto version
For a sweeter, rounder flat black, pull a double ristretto: the same dose with a shorter yield of roughly 20–25 g. Top with just 2–3 fl oz (60–90 ml) of water. Our guide to ristretto vs lungo explains how shot length changes flavor.
Iced flat black
Fill a small glass with ice, add 2 fl oz (60 ml) cold water and pull the double shot over the top. Stir and drink immediately.
Troubleshooting a flat black
| Problem | Likely cause | Fix |
|---|---|---|
| Sour and sharp | Under-extracted shot | Grind finer or extend the shot slightly |
| Harsh and bitter | Over-extracted shot or boiling water | Grind coarser and let the kettle rest a minute |
| Watery | Too much water for the cup | Cut water to 2–3 fl oz |
| No crema | Water poured on top of the espresso, or stale beans | Water first, and use freshly roasted coffee |
Best coffee for a flat black
A short black drink shows every detail of the coffee, so choose something you enjoy straight. Our African Espresso blends Kenya, Tanzania and Ethiopia in a medium-dark roast with red fruit and chocolate notes. For a classic, chocolatey cup, the 6 Bean Blend is a dark roast house blend built for espresso. If you prefer something brighter, Colombia Medellin brings dried orange, berry and chocolate. All are roasted 1–5 days before delivery, which matters for crema.
Flat black FAQ
Is a flat black the same as a long black?
Often very close. Both are espresso with hot water, but “flat black” is informal and may mean a smaller cup or less water than a long black.
Is a flat black a flat white without milk?
In spirit, yes: same small cup and coffee strength, with water instead of steamed milk.
How much caffeine is in a flat black?
It depends on the shots. Most versions use a double espresso, so the caffeine equals a double shot. See what is a shot of espresso.
Is a flat black stronger than an Americano?
It usually tastes stronger because it uses less water per shot, though the caffeine depends on how many shots each contains.
Can I add milk to a flat black?
Then it becomes something else. A splash of milk makes it closer to a long black with milk; steamed milk makes it a flat white.
