Healthy food for your people.
So I tried out making no wine at all, tons of sausages and just a little bread. With 80 serves, my food industry looked like that:
11 farms for wheat
For bread:
2 mills
2 bakeries
For sausages:
5 swine farms
3 putcheries
I ended up having like over 200 extra sausages in storehouses. Even though 2 bakeries look a bit little for 80 serves, it worked fine, since there was always sausages to eat and most people left the inn with 100% condition.
The putcheries should all be really close to the inn and storehouse.
When the fish became available, people didnt eat if they had bread + sausages. They did eat bread + fish in case sausages were out, though.
