How to Use Coffee Capsules Properly (Nespresso Brew Guide)
If your capsule coffee tastes bitter, weak, or ashy, it’s probably not the capsule. It’s your cup size.
Most Nespresso machines are set to extract too much water by default. When you shorten the shot, you unlock a stronger, smoother, better-balanced espresso.
Here’s how to get the best flavour from your capsules.
Why You Should Reduce Cup Size
A standard espresso machine uses around 18–22g of ground coffee per shot. A typical capsule contains about 5g of coffee.
Trying to extract a full-length shot from a small capsule often leads to:
-
Over-extraction
-
Bitter, burnt flavours
-
Thin body
-
Ashy finish
Less water = better balance.
What’s the Ideal Capsule Ratio?
For best results: Aim for a 1:2 ratio
Example: If your capsule contains ~5g coffee, aim for roughly 10g liquid espresso output.
On many machines, this means:
-
Shorter than default espresso setting
-
Roughly 5–8 seconds of extraction (depending on model)
How to Program Your Nespresso Cup Size
⚠️ Programming steps may vary by model. Always check your manual if unsure.
For most Original Line Nespresso machines:
-
Turn the machine on and wait for buttons to stop blinking.
-
Press and hold the espresso button.
-
Release the button when your desired cup size is reached.
-
The machine will save that volume automatically.
Next time you press the button, it will pour the same amount.
Why Default Settings Taste Bitter
Espresso extracts in stages:
-
Bright acids
-
Sweetness
-
Body
-
Bitterness
When you extend extraction too long, you pull out the final bitter compounds. That’s why longer shots often taste:
-
Harsh
-
Thin
-
Over-extracted
Shorter shots preserve sweetness and body.
Should You Use the Lungo Setting?
Only use the Lungo setting with capsules designed specifically for Lungo brewing. Standard espresso capsules are not designed for long extraction. Using Lungo mode on espresso capsules usually causes bitterness.
How to Make a Long Black with Capsules
A proper long black is made by: Hot water first, then espresso poured over it
With capsules:
-
Pull two short espresso shots (correctly sized).
-
Add 100–160mL of hot water (around 95°C).
This keeps flavour balanced and avoids over-extraction.
Can You Reuse a Capsule?
No. Most flavour and body are extracted in the first shot.
Reusing a capsule will produce:
-
Watery coffee
-
Bitter finish
-
Weak body
It won’t double your coffee, it just ruins it.
Does Reducing Cup Size Change Caffeine?
No. Caffeine extracts early in the shot.
Shortening your yield mainly reduces bitterness, not caffeine content.
Find Your Ideal Ratio
Every machine behaves slightly differently.
As a starting point:
-
1:2 ratio
-
Short extraction
-
Smooth, syrupy flow
-
No pale, watery tail at the end
Taste and adjust.
