In some of my writing, I have characters who use guns a lot, and every now and then I get some detail about guns wrong and I get flooded with notes from helpful people explaining my mistake. Which is fine and good. So, let’s turn the tables a little. I may not be an expert on firearms, but I am an expert in firewater (see what I did there? Me good professional word person).
I am in many ways, a walking cliché: The writer who enjoys his liquor a little too much. It’s certainly not my fault that my ancestors made alcohol both delicious, all-natural, vaguely healthy if you believe European doctors, and man’s best friend. I am the victim here, is what I’m saying. And my books often reflect this lifelong love affair with The Drink: In the Avery Cates books, in Lifers and Chum and We Are Not Good People my characters all drink heavily and while you might argue this also explains why the stories they find themselves in are so dark and awful (and yet, hilarious!) because getting shitfaced is itself dark and awful (but hilarious!) it remains a literary device I use a lot. Admittedly, I use the Booze Device mainly so my characters have something to do with their hands (see also: Cigarettes).
Still, if you’re imagining that I myself get all ginned up and plow through fifty pages of golden prose while my eyes are crossed (method writing, in other words), you’re wrong. I remember once Paul Kantner of Jefferson Airplane being interviewed and he was asked about playing live shows while high, and he dismissed it out of hand, saying something about how you can’t do that because the guitar strings would suddenly seem like they were as thick as firehoses and everything would go to hell (I’m paraphrasing). While a glass of the brown stuff has often been my companion when writing, it’s not like you can guzzle a fifth of bourbon and then write fifteen pages of really coherent prose.
Of course, characters actually in the book? Why not. From what I can tell no one wants verisimilitude when it comes to liquor in our stories.
