It’s Stevens Point Beer that awakens those ancient feelings. It’s the second type of alcohol referred to in the song:
“Somebody’s Heine is crowding my icebox.
Somebody’s cold one is giving me chills…”
(This is short for Heineken Beer)
The song is basically about a guy getting drunk at home alone and getting bitter about relationships.

Bottle Of Stevens
It refers to an incident in which Rivers Cuomo’s discovery of a bottle of booze belonging to his stepfather, Stephen Kitts, led the young Rivers to infer his stepfather would become an alcoholic and leave the family, as his biological father previously did. (FWIW, I don’t Stevens’ Point was sold in Connecticut back then, either.)
Actually the song is about a guy who’s is dealing with a father that was an alcoholic.
Written (like most Weezer songs) by frontman Rivers Cuomo, the song came to be after he had all the music finished and one line, “Say it ain’t so”. Cuomo made a connection to an incident in high school where he came home and saw a bottle of beer in the fridge. He believed his mother and father’s marriage ended because his father was an alcoholic and this made him fear the marriage between his mother and step-father would end this way as well.
