To be honest, we've never really heard of Fireball Whisky (it certainly wasn't on the circuit in our J1 days) but if it's anything like it's description, we'll stick to the tequilas thanks.
Obsev managed to find four grandmothers who'd never heard of or tasted 'Fireball Whisky' either and decided that, because this is the internet, they'd be the perfect test subjects to relay to the rest of the world what the rank-sounding alcohol tastes like.
As you can imagine, the results were very entertaining.
