You have the capacity to store enough for "a few weeks" I have over 110 days of food stored in Libidizedd. I know that other cities in Astrum have the same, or more.
Keep in mind that Giask is an outlier with your massive food requirements. Youu *will* have special needs that most don't. You will have to build more granaries, and pay more attention to your food situation than, say, the Margrave of Gaston or Chrysantalys. But that's also why you make 3k+ gold per tax. Get used to the fact that being Margrave of Giask puts you in a special situation. You *will* have to do more work than most other city lords.
