Vault City Brewing makes modern sour beers in Portobello, Edinburgh. But there is no need to hop on a plane and set off to rainy Scotland to try what they 'brewed up'. You can head to HOPS Beer Bar Budapest on Thursday, where Vault City beers will be on tap from 5 pm. Come prepared, as they have the magical power to make even the most unwilling beer taster go for an extra pint.
