No, they won't hold carbonation at all. They are meant to pull a vacuum, for canning, and so won't seal with any pressure from the inside. Also, the glass isn't rated for carbonation so even if they do manage to seal, they will explode.

Works great for still (non-carbed) cider. They make half gallon jars which are very inexpensive compared to growlers. I pour them into and server from a pitcher though... something about the aesthetics of having a jar of alcohol on the table doesn't always work with my guests.
As Yooper said, they don't work at all for carbonation, years ago I tried to bottle beer in them (some 'expert' told me it would work, it doesn't). It is pretty safe though, the tops pop way before they will burst.
They're fine for still things, but not for carbonation. Mason jars are meant to contain a vacuum NOT the outward pressure of carbonation.
