Coffee Drink
Decaf Espresso: Caffeine, Recipe and Dialing In
Decaf espresso is a small, concentrated coffee brewed under pressure from decaffeinated beans. It keeps espresso’s concentrated texture while containing much less caffeine than regular espresso.

Serving, sugar and sources
- Serving
- 1 home shot: 36 g espresso from an 18 g dose
- Made with
- 18 g decaf beans → 36 g liquid espresso
- Sugar
- 0 g reference. No milk, sugar or syrup; generic USDA decaf-espresso entry.
- Preparation
- About 5 minutes; machine warmed
The caffeine example is a named capsule product family. Energy and sugar use a decaf-specific USDA entry for the 36 g serving. See the full calculation or label comparison.
Key Takeaways
- 1Choose a cocoa-led decaf for a mellow espresso or a coffee flavor that carries into milk drinks.
- 2Give a new decaf its own grind adjustment instead of assuming the setting for your regular beans will work.
- 3Start with 18 g decaf coffee to 36 g espresso, then adjust grind for the beans while keeping dose and target yield steady.

- Time:
- About 5 minutes, with the espresso machine ready
Ingredients
- 18 g decaffeinated coffee beans

Method
- Prepare. Warm the machine and cup. Use a clean, dry basket compatible with an 18 g dose.
- Dose. Grind 18 g decaf beans finely, distribute evenly and tamp level.
- Extract. Tare the empty cup on a scale. Brew to 36 g liquid espresso; 93°C (199°F) is an adjustable starting temperature.
- Taste. Stir and sip when comfortable. On the next shot, keep dose and yield fixed while adjusting grind to improve flow and flavor.
Estimated nutrition: 3 kcal · 0 g total sugar. Per 36 g plain decaf espresso.
Recipe notes
For caffeine information about this ground-coffee recipe, consult the coffee producer; capsule figures describe a different preparation.
For a new coffee, compare this starting point with the roaster's guidance.
Use the espresso brewing guide for equipment setup, then keep the recipe’s decaf dose and yield consistent.
This dose and yield also appear in Decent Espresso's manufacturer guide. Use this as a repeatable starting point, recording time alongside flow and taste.
Decaf Espresso Caffeine and Serving Size
Decaf espresso retains some caffeine. For a named example, Nespresso lists 2–4 mg per Original decaf cup. That capsule figure does not estimate the caffeine in our 18 g ground-coffee recipe; ask your roaster for applicable serving data.
Published caffeine examples and their limits
Swipe to see all columnsScroll to see all columns
| Evidence | Published amount | What the number applies to |
|---|---|---|
| Nespresso Hong Kong FAQ | 2–4 mg per cup | Its Original decaffeinated capsule range |
| McCusker and colleagues, 2006 | 3.0–15.8 mg per shot | Six decaf espresso samples from one Starbucks outlet in the study |
| This home recipe | Unmeasured | Your beans, dose and extraction determine the actual result |
The study is historical evidence of variation, not a current Starbucks specification or the range for all decaf espresso. Ask the café what dose and serving it means by a “double.”
The FDA's commonly quoted 2–15 mg per 237 ml (8 US fl oz) example concerns brewed decaf, not this small shot. See decaf coffee for that serving context. If you must avoid caffeine, use product-specific advice rather than treating decaf as zero.
Calories and Sugar in the Plain Shot
The plain 36 g shot has an estimated 3 kcal and 0 g sugar, using USDA decaf-espresso data.
Decaf espresso calorie calculation
The USDA decaffeinated-espresso entry, FDC 174125, supplies the energy estimate: 9 kcal per 100 g × 36 g = 3.24 kcal, rounded to 3 kcal. Its sugar entry is 0 g.
Milk and sweeteners add their own calories and sugar. Adding water changes concentration and cup size, but it does not remove the caffeine already in the shot. For a milk-based serving with separately counted ingredients, use decaf latte.
Planning the Decaf Espresso Yield
“Dose” means dry ground coffee; “yield” means the liquid beverage collected. Crema changes apparent volume, so 36 g espresso is not a claim of 36 ml (1.2 US fl oz), or two 30 ml (1 US fl oz) shots.

| Dry dose | Beverage mass target | Dose-to-yield ratio | Role in a tasting trial |
|---|---|---|---|
| 18 g | 27 g | 1:1.5 | Shorter yield to compare |
| 18 g | 36 g | 1:2 | Starting recipe |
| 18 g | 45 g | 1:2.5 | Longer yield to compare |
Changing yield affects extraction as well as dilution; compare the shorter and longer yields to find the balance you enjoy. The espresso ratio guide offers more comparisons.
Decaf Espresso Troubleshooting
Treat a new decaf bag as a new coffee. Start with the roaster's recommendation when available, then adjust one variable at a time.
| Observation | First check or trial |
|---|---|
| Fast flow, thin and sharply sour | Grind a little finer while keeping 18 g dose and 36 g yield |
| Very slow flow and harsh taste | Check basket capacity and try a slightly coarser grind |
| Spraying or uneven flow | Improve distribution and a level tamp before changing the ratio |
| Even flow but still sour | Compare a slightly longer yield, keeping other settings steady |
| Balanced but too intense | Add hot water after brewing for a small Americano |
Do not keep tightening the grind to force a time target if the cup is getting worse. For equipment setup and extraction detail, see the espresso brewing guide.
What Does Decaf Espresso Taste Like?
Decaf espresso keeps the small serving and concentrated mouthfeel of espresso. Choose chocolate-and-nut notes for a more mellow, bittersweet style, or a fruit-led coffee for a brighter shot.
I prefer a cocoa-led decaf for espresso because it gives me a clear coffee finish without relying on smoky roast flavors.
Stir before tasting. Freshness and preparation influence crema, so taste the whole drink before deciding whether to adjust the shot.
Choosing Decaf Beans
Use beans sold as decaffeinated, with roast and flavor information you find useful. The NCA describes caffeine removal at the green-bean stage; Swiss Water explains one specific water-based system.
| Choice | Practical distinction |
|---|---|
| Decaf espresso versus regular espresso | Same pressure-brewing idea; the coffee has undergone caffeine removal |
| Decaf espresso versus brewed decaf | Filter brewing and a larger serving than the espresso recipe |
| Decaf espresso versus a decaf latte | Milk is added to a decaf espresso base; it does not cancel residual caffeine |
| Whole beans versus capsules | Capsules use pre-portioned coffee; the home recipe uses an 18 g basket |
If you share a grinder with regular coffee, follow its maker's cleaning and retention advice. Clearing retained regular grounds helps keep them out of the next decaf dose.
Common Questions
Can I Use Decaf in an Ordinary Espresso Machine?
Yes, using beans and a dose appropriate for the machine and basket. A capsule machine needs compatible decaf capsules. For a moka pot, follow the separate moka-pot method with decaf beans.
Is This One Shot or a Double?
It is one 18 g double-basket extraction yielding 36 g total, served together. It does not mean two separate modern double-basket extractions. For serving terminology, see doppio.
Can I Make Decaf Espresso Without a Machine?
Use a pressure-capable manual espresso brewer if you want espresso itself. For a stovetop alternative, brew decaf beans with the moka-pot method; for a milk drink, the decaf latte recipe gives measured moka and instant-coffee options. These alternatives have their own caffeine basis.
