Homer. He drinks cerveza in almost every episode of the Simpsons for the past 22-23 years, and I have barely seen Moe drink a lick of beer, even alcohol, but maybe I've seen him drink a martini at like a party o something, not sure, but Barney Gumble is probably the only person who can beat Homer at cerveza drinking, and Barney goes on and off at trying to go straight and non-alcoholic. But I guess Moe has a little bit every now and then ;P!
Homer definately. The only person that could probably beat him is Barney Gumble, but he wasn't in the question. tu see homer at Moe's tavern o even at inicial drinking beer, whereas tu never really see Moe drinking beer.
