A lot of fanfics write that Dick doesn't really drink alcohol much and that Jason likes Scotch. What do the comics say (if anything)?
I know Bruce never drinks, Jason gets pictured in bars often having a beer, I believe I’ve seen Dick and Babs enjoy red wine and also beer together.
okay fun/random thing, WAY back in the mists of time when parents freaked out that superhero comics were making their son’s gay (the 1950s, it was a thing) comic book publishers came up with a “Comics code” which was mostly about sex, but is also why there’s no swearing in comics, or not much any ways DC ditched the code formally in 2011, but old habits die hard, I’d guess that’s why you don’t see much hard alcohol in comics, the code
but to answer your question I’ve never seen a comic in which Dick says he doesn’t drink, or a comic where Jason drinks scotch, I’ve seen them both drink beer
