A study by consultancy OnStrategy has identified the most memorable brands in Portugal among adults aged 18 to 75. The research analyzed over 2,000 brands across 70 economic sectors, evaluating qualities such as authenticity, strength, and inspiration.

Delta was identified as the top most memorable brand overall, followed by Sagres and Olá. The ranking also included prominent names such as Caixa Geral de Depósitos, TAP, CTT, EDP, Galp, Continente, and Super Bock. 

The study noted that brand memorability varies by age group. For instance, Sagres led among those aged 18 to 45, while Olá was most memorable for the 46 to 60 demographic. Delta held the top position for the 61 to 75 age group. 

The methodology followed the ISO 20671 international standard for assessing brand strength, utilizing twelve indicators including solidity, vitality, authority, personality, and inspiration. The findings were based on spontaneous identification by more than 50,000 citizens.
