Answered quickly

Which is the best espresso for a portafilter machine?

The best espresso for a portafilter machine is a bean blend of Arabica and Robusta specifically roasted for espresso. It provides more body, a stable crema, and a balanced taste. Blends with approximately 50% Arabica and 50% Robusta are particularly popular.

The Truth

The caffeine content is primarily determined by the coffee variety and dosage – not by the color of the bean.

Briefly Explained

Strong taste does not automatically mean more caffeine.

The most important criteria

What makes a good espresso for a portafilter machine?

1. The Right Roast

For portafilter machines, the following are particularly suitable:

  • medium-dark to dark roasts
  • gently and slowly roasted beans
  • low acidity
  • intense roasted aromas.

Roasts that are too light can quickly taste fruity or sour in a portafilter.

2. The Right Bean Ratio

Arabica : Robusta

  • fine aromas : strong body
  • slight sweetness : more crema
  • mild : intense flavor
  • less caffeine : higher caffeine content

Many baristas prefer a balanced blend of both varieties for portafilter machines.

Barista Knowledge

Why is 50% Arabica and 50% Robusta so popular?

A balanced blend combines the strengths of both beans:

  • full-bodied flavor
  • creamy texture
  • dense crema
  • low acidity
  • long-lasting aftertaste.

This is precisely why many Italian espresso bars rely on blends with a Robusta content.
