Product Overview
The 9Barista Stovetop Espresso Machine is the only stovetop espresso machine in the world that delivers authentic 9-bar pressure at 93°C — the exact conditions of a professional café machine. No electricity. No pump. No compromise. Just exceptional espresso from your hob.
Designed by William Playford, an espresso enthusiast and aerospace engineer, the 9Barista applies principles from jet engine engineering — high pressures, meticulously controlled temperatures, and precision machining — to create genuine espresso on any stovetop. Unlike traditional moka pots that brew at 0.5-2 bar, the 9Barista achieves true espresso extraction with rich crema that rivals premium counter machines.
🚀 Aerospace Engineering Meets Espresso: The 9Barista uses a patented twin-boiler system that creates exactly 9 bars of steam pressure while maintaining water temperature at precisely 93°C. This is the same engineering precision used in jet engines, applied to making perfect espresso on your stovetop.

How the 9Barista Works — Aerospace Engineering Applied to Espresso
The 9Barista uses a patented twin-boiler system that mirrors the physics of aerospace pressure systems. Here's how it creates true 9-bar espresso on your stovetop:
Stage 1: High-Pressure Primary Chamber (Lower Boiler)
Cold water (110-120ml) goes into the lower boiler — the high-pressure primary chamber. Heat from your stove raises this water to 179°C, creating exactly 9 bars of steam pressure inside the sealed lower boiler.
Stage 2: Heat Exchanger & Temperature Control (Upper Boiler)
The upper boiler contains brewing water that passes through a heat exchanger. As the lower boiler reaches 9 bars, the upper boiler water is heated to precisely 93°C — the optimal espresso extraction temperature.
Stage 3: Extraction at Professional Standards
When pressure reaches 9 bars, a spring-operated valve opens. The 9-bar steam pressure forces the 93°C water through the coffee puck at professional café conditions, extracting a genuine double espresso with rich crema in 25-30 seconds.
Why This Engineering Matters: Traditional moka pots brew at 0.5-2 bar with water exceeding 100°C, producing strong coffee but not espresso. The 9Barista achieves both 9-bar pressure AND 93°C temperature simultaneously — the first and only stovetop machine to do so.

-
Temperature: Often exceeds 100°C (too hot for optimal extraction)
-
Result: Strong, concentrated coffee — but not espresso
-
Crema: Little to no crema
-
Taste: Bitter, over-extracted flavors common
9Barista
-
Pressure: 9 bar (professional café standard)
-
Temperature: Precisely 93°C (optimal espresso extraction)
-
Result: True espresso — meets international espresso definition
-
Crema: Rich, thick crema like café machine
-
Taste: Balanced, complex, café-quality espresso
9Barista Mk.1 vs Mk.2 — Which Should You Buy?
Mk.1 (Original Model)
- Brass heat exchanger
- Cast finish on some surfaces
- Silicon thermal break
- Plastic chimney
- 2-year warranty
- Excellent espresso quality
- Lower price point
Mk.2 (Upgraded Model)
- Stainless steel heat exchanger (improved heat resilience)

Frequently Asked Questions
Is the 9Barista true espresso or just strong coffee like a moka pot?
True espresso. The 9Barista is the only stovetop machine that achieves 9 bar pressure at 93°C — the exact conditions of professional café machines. Traditional moka pots brew at 0.5-2 bar with water exceeding 100°C, producing strong coffee but not espresso. The 9Barista produces genuine espresso with rich crema that is indistinguishable from premium counter machines when beans and grind are dialled in.
What stove types work with the 9Barista?
The 9Barista works on gas, electric halogen, electric ring, ceramic hobs, traditional stoves (Aga, Rayburn), and camping gas stoves. For induction hobs, you need an induction adaptor plate (sold separately). Basically, if it produces heat, the 9Barista will work on it.
How long does it take to make espresso with the 9Barista?
3-6 minutes from cold start depending on your stove's heat output. Gas stoves tend to be faster than electric. The extraction itself takes 25-30 seconds once pressure is reached. For subsequent shots, the machine must cool between uses, so allow 3-6 minutes between shots.
Can I make multiple espressos back-to-back?
The 9Barista produces one double shot (40ml) per cycle and must cool between uses. You can make consecutive shots, but allow 3-6 minutes cooling time between each shot. This makes it perfect for 1-2 people but less suitable for entertaining large groups who all want espresso simultaneously.
Do I need electricity to use the 9Barista?
No — the 9Barista requires zero electricity. It works purely from heat applied by your stove. This makes it perfect for camping, caravans, boats, off-grid living, or anywhere without reliable electricity. You just need a heat source.
Is the 9Barista portable for camping or travel?
Yes — the 9Barista is fully portable. No cords, no water tank, no electricity required. Pack it dry and padded and take it camping, caravanning, to holiday homes, or anywhere you travel. Works perfectly with portable camping stoves for genuine espresso in remote locations.
What's the difference between Mk.1 and Mk.2?
Both produce identical espresso quality. The Mk.2 features upgraded materials (stainless steel heat exchanger, ceramic thermal break, anodised aluminium chimney), improved durability (50% larger O-ring), premium finish (fully machined castings), and extended 5-year warranty (vs 2-year on Mk.1). Choose Mk.1 for excellent espresso at lower cost, or Mk.2 for premium materials and longer warranty.
Does the 9Barista come with a grinder?
No — the 9Barista is just the espresso machine. You need a separate grinder capable of fine espresso grind. Di Pacci offers bundle packages that include a grinder, or you can purchase one separately. The 9Barista works with any quality burr grinder.
How difficult is the 9Barista to use?
There's a learning curve to dial in your grind size, dose, and timing, similar to any espresso machine. Once dialled in, operation is simple: fill water, add ground coffee, place on stove, wait for extraction, remove from heat. The 9Barista rewards the learning process with café-quality espresso. Di Pacci provides guidance and the 9Barista website has comprehensive tutorials.
Is the 9Barista worth the investment compared to a moka pot?
If you want true espresso on the stovetop, yes. Moka pots make strong coffee but not espresso — they can't achieve 9-bar pressure at 93°C. The 9Barista is the only stovetop machine that produces genuine café-quality espresso with rich crema. If you're serious about espresso and want no-electricity operation, the 9Barista is a breakthrough. If you're happy with moka pot coffee, stick with that.
