Why does the last thing you eat sometimes not come up when you vomit but something before that comes up?

Question

I threw up last night because I scraped my tongue a bit too far back and it activated my gag reflex. I’d been at dinner with a friend, and I’d had a fair amount of wine, but when I threw up it was only the food that came up and not the wine? Why is this?
