The first mention of this, I believe, was in 1988's Web of Spider-Man #38, by Fabian Nicieza and Alex Saviuk. Peter's moving out of his crummy old Chelsea apartment and he's throwing a party to celebrate (a party that ends up being attended by both Alice Cooper guitarist Dick Wagner and beer-shilling dog Spuds MacKenzie). His landlady's husband decides to surreptitiously spike the punch, and Pete downs a couple glasses before heading out to fight the Hobgoblin. It doesn't go well.
|Do not break the seal, man. That suit doesn't have a fly.|
Luckily, it turned out that the Hobgoblin couldn't even beat a drunk Spider-Man, which would prove to be a harbinger of where his career was going. The whole thing concludes with everyone having learned a valuable lesson.
|Now I know - and knowing is half the battle! SPIIIIIII-DERRRR-MAAAAAAN!|
And he never touched booze again, right? Well, no. Amazing Spider-Man #51 (2003), by J. Michael Straczynski and John Romita Jr., is one of the few occasions we see Peter willingly drinking; having Mary Jane return to him after a long absence is a pretty special occasion, I suppose. We don't know how much he drank, exactly, but the odds are it wasn't much, given that he's still conscious enough to make a total ass of himself.
|Heh heh. Ballpeen.|
Such is Peter's unfamiliarity with booze that, during his aunt's wedding to J. Jonah Jameson Sr., his roommate/nemesis Michele Gonzales was able to ply him with apple-ginger ale, convince him it was champagne, and watch him get psychosomatically hammered. And, uh, then had sex with him. But she was for-reals drunk, so it's okay, I guess?
|A similar thing happened to me at a wedding once, but the alcohol was real, and also somebody stole my tie.|

(Do they make apple-ginger ale? That sounds friggin' delicious.)
It's not just that Peter's experience with alcohol has been limited, and he hasn't built up a tolerance - it's gotta be genetic, given that both Ben Reilly...

...both of whom are clones of Peter, are total lightweights. Not depicted: that time Spidercide got into the Jackal's liquor cabinet and drank peppermint schnapps until he puked.
It's honestly for the best, given how Peter's other friends have succumbed to substance abuse, be it pills...
