Since 1940, the Grenal duo did not win the title on just four occasions: the defunct Renner was champion in 1954, Juventude almost 44 years later in 1998, Caxias, in 2000, under Tite's command, and Novo Hamburgo in 2017.

However, due to an outbreak of Spanish flu in Rio Grande do Sul, the tournament was cancelled and postponed until the epidemic subsided.

In December 2021, the Federação Gaúcha de Futebol (Rio Grande do Sul Football Federation) recognised the three participating clubs from the 1918 edition as "Honorary Champions."

Additionally, the main teams from Porto Alegre did not participate in 1937, 1938, and 1939 due to a split within the AMGEA (Associação Metropolitana Gaúcha de Esportes Atléticos) over the adoption of professionalism between clubs and their players.

In the first seven years after unification (1961–67), the Campeonato Gaúcho was contested by 12 clubs in a double round-robin format ("pontos corridos").

In 1973–74, with more of the year dedicated to the Campeonato Brasileiro, the preliminary phase of the Gauchão no longer included the Grenal duo (Grêmio and Internacional).

In 1978, the championship format became so convoluted that Grêmio found themselves in a position where they had to lose a match to secure their place in the final phase.
