"Gira, for all its refreshing qualities, can be a bit of a mischievous drink," Eidukevičius adds. "There's a running joke in Lithuanian households about 'gira explosions' because it ferments in closed containers where enormous pressure can build up like a bottle of Champagne. There's nothing quite like walking into a cellar and finding gira sprayed across the walls and ceiling like some kind of fizzy, rye-bread-scented geyser. It's a testament to how alive this drink is. It's a reminder that we're working with natural processes, and sometimes, those processes have a mind of their own."

Mr wtg's grandparents had this happen to a batch of beer they brewed. Instead of using metal caps, they pounded a cork into each bottle and put the bottles up in the attic to "age" a bit.

Hilarity ensued.
