I don't know about the wine or cheese but I have to disagree with you on the bread thing.
There are people that make multigrain, wholegrain, sourdough, etc bread based on medieval recipes and while they're not wonderbread they're also not unrecognizable as bread to a modern person and they're not terrible either. There are even people who buy the grains and stone grind it themselves to make it more authentic.
People tend to grossly overestimate the hardships of pre-industrial life. Not that things were easy because of course a lot of labor went into simple things but people have always been cooking, the biggest difference between now and then would have just been consistency since people were cooking smaller batches more frequently with less precise tools.
