A Long Black looks simple: hot water and espresso. But when you make one with a capsule machine, a few small decisions have an outsized effect on flavour. Use too much water, run the capsule for too long or pour things in the wrong order and a potentially rich, aromatic coffee can quickly become thin, bitter or flat.
The good news is that you do not need barista equipment or complicated recipes to improve it. A capsule machine can make an excellent Long Black when you treat the capsule as a concentrated espresso source and build the drink around it.
Here is the method we recommend at JustFreshRoasted.
What Is a Long Black?
A traditional Long Black is made by adding espresso to hot water. That order matters. The hot water goes into the cup first, then the espresso is extracted over the top.
Compared with an Americano, which is commonly made by adding hot water to espresso, a Long Black is designed to retain more of the crema and aromatic character on the surface of the drink. The result should be fuller and more concentrated than a large black coffee, while still being easier to sip than a straight espresso.
A good Long Black should have:
· A rich, rounded body
· Clear sweetness and aroma
· Enough intensity to remain satisfying after dilution
· A clean finish without excessive bitterness
· A crema layer that still carries aroma across the top of the cup
The 7 Steps to a Better Long Black From Coffee Capsules
1. Warm the machine properly
Give your capsule machine time to come fully up to temperature before brewing. A machine that is only just switched on can produce a cooler, less consistent extraction. If your machine allows it, run a short water-only cycle first. This also helps rinse the brew path before you make the coffee.
2. Preheat the cup
A cold ceramic cup can pull heat out of the drink immediately. Rinse the cup with hot water, let it sit briefly, then empty it before making your Long Black. It is a tiny step, but it helps the finished coffee stay hotter and taste more balanced.
3. Add hot water first
Put the hot water into the cup before you brew the capsule. This is the defining step in a Long Black and helps preserve the crema when the espresso lands on top.
Start with around 80-100 ml of hot water. You can adjust from there depending on the strength you prefer, but starting smaller is better than drowning the coffee and trying to recover flavour afterwards.
4. Use the espresso or short-cup setting
For most Nespresso Original-style compatible machines, use the espresso or short-cup button rather than the lungo setting. You want a concentrated extraction from the capsule, not a large volume of water forced through the same dose of coffee.
As a practical starting point, aim for roughly 30-40 ml from one capsule. If your machine is programmable, this is a useful range to work around before fine-tuning to taste.
5. Extract the coffee directly over the hot water
Place the preheated cup containing the hot water under the machine and extract the capsule directly on top. You should see the crema form and spread across the surface rather than disappearing immediately into a large volume of water.
6. Taste before adding more water
This is where many Long Blacks go wrong. People often make the drink to a predetermined cup size rather than to flavour. Taste it first. If it is too intense, add a small amount of hot water. If it already tastes balanced, stop there.
7. Never run the same capsule twice
Once the useful soluble flavours have been extracted, pushing another full shot of water through the same capsule mainly increases dilution and pulls more dry, bitter compounds into the cup. If you want a larger or stronger Long Black, use a second capsule instead of over-extracting the first one.
How Much Water Should You Use?
There is no single correct cup size because capsule intensity, roast development and personal taste all differ. But the relationship between coffee and water is what determines whether the drink tastes rich or washed out.
· Strong and compact: about 60-80 ml hot water plus a 30-40 ml espresso extraction.
· Balanced everyday Long Black: about 80-100 ml hot water plus a 30-40 ml espresso extraction.
· Larger cup: use more hot water carefully, or consider two capsules if you want to retain strength and body.
The biggest mistake is using the lungo button simply because you want more coffee in the cup. A longer extraction does not create more coffee flavour; beyond a point, it creates more dilution and bitterness.
Water Temperature Matters More Than Most People Think
For the added water, use freshly heated water that is hot but not aggressively boiling when it reaches the cup. Boiling water is not automatically disastrous, but letting the kettle settle briefly makes the drink easier to control and avoids needlessly overheating the cup.
If your Long Black regularly tastes sharp, hollow or surprisingly bitter, do not assume the capsule is the problem. Check the machine temperature, cup temperature, extraction volume and water dilution before changing coffee.
Choose a Capsule With Enough Body for a Long Black
Because a Long Black deliberately dilutes espresso, the capsule needs enough flavour and body to remain present after the hot water is added. Chocolate, caramel, molasses, toffee and nutty flavour profiles often work particularly well because they tend to remain clear and satisfying as the drink opens up.
At JustFreshRoasted, we roast and pack our coffee capsules in Melbourne. Our range is designed for original/classic Nespresso-compatible systems, and different coffees give you different ways to build the drink.
For a sweeter, balanced style, browse our Organic Nespresso-compatible coffee capsule range. If you prefer a bolder capsule with more impact, Mighty Moka is developed specifically for capsule brewing and is best used on the espresso or short-cup setting.
One Capsule or Two?
For a normal Long Black, start with one capsule and control the water volume. If you prefer a large mug or a particularly strong black coffee, two capsules will usually produce a better result than extending one capsule into a very long extraction.
That gives you more actual coffee in the cup rather than simply extracting the same small dose for longer. It also lets you keep the coffee-to-water ratio in a range where the drink still has body and sweetness.
Small Adjustments That Make a Noticeable Difference
· Keep the machine clean. Old coffee oils and scale can mute sweetness and introduce stale or harsh flavours.
· Use fresh water. Water that has been repeatedly boiled or left sitting for long periods can make coffee taste flat.
· Do not automatically fill the mug. Choose the final volume according to taste, not the size of the cup.
· Use a second capsule for more strength. Do not compensate for weak flavour by repeatedly extending the extraction.
· Try the coffee before adding milk. A small dash of milk is perfectly fine if that is how you enjoy it, but first make sure the Long Black itself is balanced.
A Simple Long Black Recipe to Remember
If you want one reliable starting recipe, use this:
· Preheat the machine and cup.
· Add 80-100 ml of hot water to the cup.
· Insert one fresh coffee capsule.
· Select the espresso or short-cup setting.
· Extract approximately 30-40 ml of coffee directly over the water.
· Taste it before deciding whether it needs any more water.
· For a larger, stronger drink, use a second capsule rather than running the first one again.
From there, change only one variable at a time. Add a little less water if you want more body. Add a little more if the drink is too concentrated. Try a different capsule if you want more chocolate, fruit, sweetness or intensity. Within a few cups, you will have a Long Black recipe that suits your machine and your taste far better than simply pressing the lungo button and hoping for the best.
Better Long Blacks Start With Better Control
The advantage of capsule coffee is consistency and convenience, but you still control the most important part of a Long Black: how the espresso and water come together. Keep the extraction short, put the water in first, avoid excessive dilution and use a capsule with enough flavour to carry through the finished drink.
Those small changes are usually enough to turn a thin or bitter capsule coffee into a richer, smoother and much more satisfying Long Black.
