For this session sour, we didn’t want to bang the same old drum, stick to what we know, or take on the challenge alone. We recruited our pals at Thirsty Cambridge, House of Trembling Madness and The Caledonian Craft Beer Merchant, who paid a visit to the Vault City Brewery to lend a hand for our latest indie collaboration. A sweet shop sensation was born, with delicious flavours of delicately tart raspberry, smooth vanilla and creamy lactose alongside our golden sour base.
