In this OpenDev, the Granary doesn't become available until the Early Modern Era.  (What I would relabel the Renaissance.)  That's wwwwaaaayyyyyy too late.  The ANCIENT Egyptians had granaries for Pete's sake.

If the problem is that it's too powerful, then weaken it.  In Truth, the primary reason for building granaries is to alleviate the effects of famine.  So unless they plan to introduce that kind of event, there really wouldn't be any Granary effects.  (A granary doesn't provide MORE food for the citizens to consume.  It's purely for storage, just in case the extra is needed.  As in, a famine is occurring.) 

Granary is ancient era

We must have different games then.  Yes, you can BUILD it in the Ancient Era.  But you can't USE it until the Early Modern Era.  (Next time you play, take a closer look at the red text on the Granary panel.)  To clarify, you can't use the Granary until you have researched the Supply Line tech.... which is sooooo far up the tech queue, a player would have an extremely hard time finishing researching it until well into the Early Modern Era.

You should pay closer attention to the tooltip. It shows that the next upgrade to the granary infrastructure in the tech tree is in the Early Modern era. The Granary is usable once you have built it in your city, you don't need to research Supply Lines to get it.

As you can see here, the red text is talking about the next infrastructure of the Grain Storage family, Grain Silos.

As a player I don't expect to have any important information (since it is red in color) relating to something that I haven't yet been able to build. From my point of view this information is not in its place and I propose to delete it or else to just specify (and not in red font) the era in which the following construction will be produced.
