AeroPress vs Espresso: Can AeroPress Replace an Espresso Machine
A detailed comparison of manual AeroPress brewing versus machine espresso extraction—understanding pressure, crema, and what "espresso" really means
Quick Answer
AeroPress cannot produce true espresso because it lacks the 9 bars of pressure required for authentic espresso extraction. However, AeroPress creates a concentrated coffee similar to espresso that works well for milk drinks. For genuine espresso with crema and full body, an espresso machine remains necessary.
AeroPress and Espresso: Entity Definitions
AeroPress Definition
AeroPress: Manual brewing device using air pressure (0.35-0.75 bar) to force water through coffee grounds, producing concentrated coffee through a combination of immersion and pressure extraction.
- • Pressure: 0.35-0.75 bar (hand-generated)
- • Extraction time: 30-90 seconds
- • Output: 6-8 oz concentrated coffee
- • Temperature: 175-185°F typical
Espresso Definition
Espresso: Coffee extraction method using 9 bars of pressure to force hot water (195-205°F) through finely-ground compacted coffee, producing a concentrated shot with crema.
- • Pressure: 9 bars (machine-generated)
- • Extraction time: 25-30 seconds
- • Output: 1-2 oz per shot
- • Temperature: 195-205°F

| Pressure | 0.35-0.75 bar | 9 bars (standard) |
| Crema Production | Minimal or none | Rich, thick crema |
| Body/Mouthfeel | Medium, clean | Full, syrupy, viscous |
| Equipment Cost | $30-40 | $100-2,000+ |
| Learning Curve | Low to moderate | Moderate to high |
| Portability | Excellent | None (countertop) |
| Milk Drink Suitability | Good (concentrated) | Excellent |
| Maintenance | Minimal | Regular (descaling, cleaning) |
Why Pressure Matters: The Science of Espresso Extraction
True espresso requires 9 bars of pressure (130 PSI) to create the unique extraction dynamics that define the beverage. At 9 bars, water penetrates the compacted coffee puck at high velocity, emulsifying oils and creating the colloidal suspension known as crema. This pressure also drives the extraction of specific compounds responsible for espresso's characteristic intensity and body.
AeroPress generates approximately 0.35-0.75 bar (5-11 PSI) through manual plunging—roughly 12-25 times less pressure than an espresso machine. While this pressure does accelerate extraction compared to drip brewing, it cannot emulsify oils into crema or extract the same compound profile. The result is concentrated coffee, not espresso.
The Specialty Coffee Association defines espresso specifically as "a 25-35 ml beverage prepared from 7-9 grams of coffee through which clean water of 195°-205°F has been forced at 9-10 atmospheres of pressure." By this definition, AeroPress cannot produce espresso regardless of grind size, dose, or technique modifications.
However, the AeroPress AeroPress produces can substitute for espresso in many applications. The concentrated output (when using less water) provides sufficient coffee intensity to stand up to milk in lattes and cappuccinos. The lack of crema matters little once milk is added, as the foam integrates with or replaces the crema layer.
Optimizing AeroPress for Espresso-Style Coffee
AeroPress Espresso-Style Recipe
- 1. Grind: Fine grind (espresso-fine, similar to table salt)
- 2. Dose: 18-20 grams of coffee
- 3. Water: 50-60ml at 195-205°F
- 4. Method: Inverted AeroPress method
- 5. Bloom: Add 20ml water, stir gently, wait 30 seconds
- 6. Fill: Add remaining water to reach target weight
- 7. Steep: 60-90 seconds total contact time
- 8. Plunge: Press firmly and steadily (30 seconds)
- 9. Result: 40-50ml concentrated coffee
This AeroPress recipe produces a 1:2.5 to 1:3 ratio brew—stronger than standard AeroPress coffee but not true espresso. The concentrated output works well as a base for milk drinks, providing enough coffee flavor to remain detectable after milk addition.
Using a metal filter (instead of paper) increases body and allows more oils through, approximating espresso mouthfeel more closely. The Fellow Prismo attachment adds a pressure-actuated valve that increases resistance during plunging, though still far below true espresso pressure.
When to Choose AeroPress vs Espresso Machine
Choose AeroPress When:
- • Budget constraints limit equipment spending
- • Travel or office brewing is needed
- • Milk drinks are the primary goal
- • Space is limited
- • Simplicity and easy cleanup matter
- • Experimentation with recipes is enjoyable
- • Black espresso drinking is rare
Choose Espresso Machine When:
- • Authentic espresso is the goal
- • Crema is important for enjoyment
- • Black espresso is regularly consumed
- • Latte art is a priority
- • Full body and syrupy mouthfeel are desired
- • Entertaining guests with espresso is planned
- • Long-term investment in equipment is feasible
AeroPress vs Espresso for Milk-Based Drinks
The gap between AeroPress and espresso narrows significantly when milk enters the equation. A cappuccino or latte contains 6-12 oz of milk, which dilutes and masks many of the differences between true espresso and AeroPress concentrate.
For home baristas primarily interested in milk drinks, AeroPress provides a cost-effective entry point. The concentrated AeroPress output (using the recipe above) delivers sufficient coffee flavor to create satisfying lattes without the $500+ investment in an espresso machine.
However, espresso machines offer milk steaming capabilities that AeroPress lacks. Creating true microfoam for latte art requires a steam wand—something only espresso machines provide. AeroPress users must use separate milk frothers (electric or manual) that produce foam rather than the velvety microfoam achievable with steam.
The quality of milk drinks from AeroPress concentrate depends heavily on milk preparation. A well-frothed milk using an electric frother combined with strong AeroPress concentrate rivals entry-level espresso machine results. However, the espresso machine's steam wand produces superior texture and integration.

Frequently Asked Questions
Can I make real espresso with AeroPress?
No. True espresso requires 9 bars of pressure, which AeroPress cannot generate. AeroPress produces concentrated coffee that can substitute for espresso in milk drinks but lacks the crema, body, and extraction characteristics of authentic espresso.
Is AeroPress coffee stronger than espresso?
No. While AeroPress can produce concentrated coffee, espresso extracts more soluble compounds per unit volume due to the high-pressure extraction. Espresso typically has higher Total Dissolved Solids (TDS) concentration than even the strongest AeroPress brew.
Can I use AeroPress concentrate for lattes?
Yes. AeroPress concentrate works well for lattes, cappuccinos, and other milk drinks. Use a 1:2 coffee-to-water ratio in the AeroPress, then dilute with milk as you would with espresso. The coffee flavor remains detectable through the milk.
Does the Fellow Prismo make AeroPress into an espresso maker?
No. The Fellow Prismo adds a pressure-actuated valve that increases resistance during plunging, but it still cannot generate the 9 bars required for true espresso. It does improve body and concentration compared to standard AeroPress brewing.
Which is more economical: AeroPress or espresso machine?
AeroPress is significantly more economical initially ($30-40 vs $100-2,000+). However, if your goal is daily espresso drinks, a budget espresso machine may be more satisfying long-term. Calculate costs based on your specific coffee goals and consumption habits.
Final Verdict: Complementary, Not Competitive
AeroPress and espresso machines serve different purposes despite both producing concentrated coffee. AeroPress excels at portable, affordable, and convenient brewing that approximates espresso for milk drinks. Espresso machines deliver the authentic crema, body, and extraction that define true espresso.
For beginners exploring espresso-style drinks, AeroPress offers an excellent entry point. The low investment allows experimentation with concentration, recipes, and milk drinks before committing to an espresso machine purchase. Many home baristas start with AeroPress "lattes" before upgrading to a machine.
For espresso enthusiasts, AeroPress serves as a travel companion or office brewer—not a replacement for the espresso machine at home. Understanding the differences helps set appropriate expectations and choose the right tool for each situation.
