Which is better: a 1-group or a 2-group espresso machine?

Which should you choose: a 1-group or 2-group espresso machine?

Choosing an espresso machine for your café is an important decision, especially the number of group heads, which directly affects workflow and service efficiency.

Key Differences Between 1-Group and 2-Group Machines

The most obvious difference is the number of group heads, which determines how many espresso shots can be extracted at the same time.

1-Group Machine:Has one group head, allowing extraction of 1–2 cups per brewing cycle.

2-Group Machine:Has two group heads, allowing extraction of 2–4 cups per cycle, or brewing espresso while steaming milk at the same time.

They also differ in boiler systems and machine size, which significantly affect performance.

• 1-Group Machines usually have small to medium boilers, suitable for lighter, less continuous use.

• 2-Group Machines often come with larger or multiple boilers, providing more stable temperature and pressure during heavy, continuous operation.

Pros and Cons of a 1-Group Machine

Advantages

• Lower price — ideal for beginners with limited budgets

• Compact size — saves counter space

• Lower energy consumption

Disadvantages

• Slower service during busy periods

• Performance may drop during long continuous use, affecting temperature stability and taste

Pros and Cons of a 2-Group Machine

Advantages

• Higher speed — can prepare multiple drinks at once

• Supports high sales volume, especially during peak hours

• Greater stability in temperature and pressure during continuous use

Disadvantages

• Higher initial cost

• Larger footprint on the counter

• Higher electricity consumption

So, Which One Should You Choose?

Your decision should be based on these factors:

Location & Target Customers

• Small shop / low-traffic area:If expected sales are under 100 cups per day, a 1-group machine is sufficient and cost-effective.

• Prime location / business district:If you expect heavy traffic during peak hours (morning rush, lunch breaks), a 2-group machine improves speed and handles demand without compromising quality.

Budget

• Limited budget: Start with a 1-group machine

• Sufficient budget: A 2-group machine is a better long-term investment and supports future growth

Menu Style

• Mostly hot coffee drinks: 1-group can be enough

• Wide menu with many milk-based drinks: 2-group is better since you can brew and steam simultaneously

Final Recommendation

• If you run a small café, have a limited budget, and expect 50–70 cups/day or less, start with a 1-group machine.

• If you have a strong location, expect high customer volume, and plan to grow, investing in a 2-group machine from the beginning is more worthwhile long-term.

And remember — besides the machine, a high-quality coffee grinder is just as important for achieving great coffee.
