Delta coffee: the Delta Cafés brand from Campo Maior | Cafemalin

The Delta Cafés story in 90 seconds

The Delta Cafés story began in 1961 in Campo Maior, a small village in the Alentejo region of southern Portugal, when Manuel Rui Azinhais Nabeiro — a visionary young entrepreneur aged 30 — launched his brand in a 50 m² warehouse with three employees and two 30 kg roasters. His ambition: to offer the Portuguese artisan-quality coffee at a fair price, roasted using the traditional slow method that preserves its aromas. This vision would transform Portugal's coffee industry for years to come.

As early as the decades spanning 1970–80, Delta Cafés became the benchmark for Portuguese café and restaurant owners. Growth accelerated with the industrialisation of roasting in Campo Maior, the creation of signature blends (Gold, Platinum), followed by international expansion in the decade beginning in 90. In 2007, Delta launched Delta Q, its proprietary capsule system — a technological venture that established the brand in the premium home coffee segment.

Today, Delta Cafés has been Portugal's leading roasted coffee brand for more than twenty years and is present in more than 40 countries. The Nabeiro-Novadelta group — still 100% family-owned — employs more than 4 000 people and embodies a unique model of social capitalism: housing for employees, the Alice Nabeiro educational centre in Campo Maior and, since 2019, support for coffee growing in the Azores. Delta has been voted Marca de Confiança, the trusted brand of Seleções do Reader's Digest readers, in the coffee category for 20 consecutive years.

Delta Cafés expertise

What has defined Delta since 1961: 4 pillars of expertise that explain its No. 1 position in Portugal and its international reach.

Slow roasting

A Delta hallmark since 1961: traditional slow roasting in Campo Maior, preserving the beans' essential oils and developing complex, balanced aromas. This allows each blend to retain its profile in the cup.

Signature Portuguese blends

Delta blends (Gold, Platinum, Ritual) define modern Portuguese coffee: slow-roasted Arabica/Robusta blends, from Gold with its notes of honey and ripe fruit to full-bodied Ritual. Our bestseller: Delta Gold 1 kg.

Delta Q innovation

Delta Q (2007) — the brand's capsule system, Portugal's capsule market leader as early as 2012. Blends numbered by intensity (Qalidus No. 10, Qharacter No. 9, MythiQ No. 15…) and compact machines (Mini Qool, Mini MilkQool, Qool Evolution, ICONIQ) designed for the home.

Commitment to social responsibility & sustainability

Social capitalism: housing for employees, the Alice Nabeiro educational centre in Campo Maior, and support for coffee growing in the Azores since 2019. Part of the range is Rainforest Alliance certified (The Harvest Collection).

Frequently asked questions

Where does the Delta Cafés brand come from?

Delta Cafés was founded in 1961 in Campo Maior (Alentejo, Portugal) by Manuel Rui Azinhais Nabeiro, a young entrepreneur aged 30, in a 50 m² warehouse with three employees. His vision: to offer the Portuguese artisan-quality coffee at a fair price, roasted using the traditional slow method. Delta has more than 60 years of uninterrupted history and remains a family business — the Nabeiro-Novadelta group (more than 4 000 employees).

Where is Delta coffee made?

Delta is roasted in Portugal, at the historic factory in Campo Maior (Alentejo). The green beans are sourced from more than 15 producing countries — mainly Brazil, Timor, Angola, Colombia, Ethiopia and Vietnam: Delta blends green coffee from more than 50 origins. Since 2019, the brand has also supported coffee growing in the Azores, Portugal's only coffee production.

Roasting takes place slowly and at a low temperature at the Novadelta complex in Campo Maior, described by the brand as the largest roasting factory on the Iberian Peninsula. Each bag is fitted with a one-way valve.

What is the difference between Delta Gold and Delta Platinum?

These are the two signature blends in the Delta coffee beans range, each with a distinct positioning:

Delta Gold — our bestseller. An Arabica + Robusta blend: slow-roasted African Robustas and Central American Arabicas, intensity 8/10, for a clean, balanced cup with notes of honey and ripe fruit (24,50 € per kilo).

Delta Platinum — premium selection. A blend of Central American Arabica and Asian Robusta, slowly and naturally roasted, with the same intensity of 8/10 as Gold but a rounder, milder cup with a longer finish: notes of ripe fruit, caramel and chocolate (25,91 € per kilo).

Our advice: Gold for everyday coffee in the Portuguese tradition, Platinum for savouring. View the full range of Delta coffee beans.

What is Delta Q and how does it work?

Delta Q is the capsule system launched by Delta Cafés in 2007, which became Portugal's capsule market leader in 2012. Its plastic capsules, sealed with an aluminium lid, work only with Delta Q machines (Mini Qool, Mini MilkQool, ICONIQ, Qool Evolution…), which brew them under pressure (19 bar on the Mini Qool and ICONIQ).

The blends are numbered by intensity: Qonvictus No. 5 (mild), Qharacter No. 9 (balanced), Qalidus No. 10 (full-bodied), MythiQ No. 15 (very intense) and decaffeinated Deqafeinatus No. 7. Boxes of 10 (0,48 € per cup for Qalidus) or packs of 40 capsules (0,37 € per cup).

Important: Delta Q is not compatible with Nespresso Original or any other system. View the full range of Delta Q capsules.

Does Delta offer organic or Rainforest Alliance certified coffee?

Yes. Delta offers several products with sustainability commitments:

  • Delta The Harvest Collection Bio Décaféiné — 500 g coffee beans, organically grown and Rainforest Alliance certified: a decaffeinated blend of South American Arabicas and African Robustas, with an intensity of 9 on Delta's scale of 15.
  • Delta The Harvest Collection Rainforest — 1 kg Rainforest Alliance certified coffee beans: an intense, full-bodied blend of Arabica and Robusta, with an intensity of 12 on Delta's scale of 15.

More broadly, Delta has supported coffee growing in the Azores since 2019, working with more than 500 farming families, and funds social projects in Campo Maior, such as the Alice Nabeiro educational centre.

How do you choose between Delta coffee beans, Delta Q capsules and Delta Q machines?

The choice depends on your equipment and how you use it:

  • Delta coffee beans — for automatic machines with a built-in grinder or professional espresso machines with a separate grinder. Optimal aroma (ground just before extraction). Pack sizes from 500 g to 30 kg for professional use. Bestseller: Delta Gold 1 kg.
  • Delta Q capsules — for Delta Q machines only. Convenience and consistent dosing. Price: 0,48 € per cup (Qalidus). Ideal for home use.
  • Delta Q machines — if you do not yet have Delta Q equipment: Mini Qool (compact), Mini MilkQool (built-in milk tank) or ICONIQ (touchscreen), on their own or with an initial supply of capsules.

For quality in the cup alone, freshly ground coffee beans remain superior. For convenience and consistency, Delta Q capsules win.
