But these days brews are far more important to the rock n' roll star than they were in the 90s.
In 2017, a clip of the former Oasis frontman popping the kettle on - while reminiscing about the days he had four people to make cups of tea for him - went viral.
Now, the 46-year-old has given his verdict on who make the best tea bags - and it is predictably emphatic/sweary.
In footage from new rockumentary As It Was, released on Friday June 7, Gallagher declares his love for tea, before being asked which bag is the best.
While making a brew, flanked by son Gene, Liam replies: "Yorkshire...PG Tips - fuck off."
D'you hear that PG Tips monkey? You can take your tea bags and shove em up your primate arse as far as LG is concerned.
Former Oasis frontman Gallagher then elaborates on his disliking for PG Tips with a footballing analogy.
"PG Tips is like a football team that was mega, went down to the first division and it can't get back into the Premiership," he says.
"It's a little bit the opposite way around with the Yorkshire Tea, they got great tea, but they're teams are FUCKING SHITE!"
He also throws an illustrative wanker hand gesture in there for good measure.
No doubt As It Was will bring us many more of the singer's signature insights. The film follows Gallagher's return to the music scene as a solo artist and the release of his debut album As You Were.
A synopsis of the film reads: "As It Was documents the musical comeback of the decade; an honest and emotional story of how one of the most iconic rock 'n' roll frontmen went from the dizzying heights of his champagne supernova years in Oasis to finding himself ostracised and on the periphery of the rock 'n' roll world.
"Starting again alone, stripped bare and with nowhere to hide, Liam risks everything to make the greatest rock 'n' roll comeback of all time, battling against the odds to return to the top of the charts.
"Directors Charlie Lightening and Gavin Fitzgerald invite us backstage for a no-holds barred look at the life of one of the most talked-about and charismatic artists of his generation."
