"This is Vault City’s mixed fermentation base beer, the foundation of every sour we’ve brewed since 2018. Originally brewed for our brewery launch party, it showcasing our unique house mixed culture of lactobacillus and saccharomyces, delivering a refreshing tartness with layers of fruity esters and a zingy sherbet finish. A light dry-hop of Cashmere and Bramling complements the tartness with subtle hop character."

"There are many things Scotland has given to the world but perhaps the most iconic is Iron Brew.

The bold colour and unique flavour evoke a sense of national pride that’s otherwise only found when talking about our tap water. It’s timeless, like a pint at the airport.

So, here’s our take on the nation’s favourite soft drink, packed with pride and irony goodness in every sip."
