I was in the Algarve last year and tried Super Bock (not a bock mind, just a brand name), Sagres, Sagres Preta (a dark beer), Tagus, Sagres Bohemia (an amber beer of 6.7% abv). They were all much of a muchness really. I probably enjoyed Sagres euro lager as a cooler in the sun as much as any of the others.
