Another vote for coffee!!!
Maybe I'm just not envisioning the same kind of scenario here as many, because I see lots of things listed that can be made yourself. Heck, growing up on a farm in the Midwest, several of these things we regularly did/do make ourselves. Bratwurst (spiced differently to make other kinds of sausages such as pepperoni), bacon, smoked & cured ham, steak, beer/cider (never tried distillation since it's illegal, but it's certainly possible), cheese, and anything made with flour... We have thousands of bushels of wheat, corn, etc., stored on the farm so I don't think we'd run out of flour. I make sourdough bread about once a month now; of course I'd do it like every day if that's all the bread I had. So for me I guess long term it would be more like exotic spices and foods that I'd miss.
