Vault City's Tropical Sour delivers an explosion of exotic flavours: mango, mandarin and passionfruit. This fruited sour from the Scottish brewery reflects growing demand for authentic, fruit-based drinks. The beer combines sharp acidity with bright tropical notes, with fruit dominating the front end.

The Edinburgh brewer employs a unique mixed fermentation culture of Kveik and Lactobacillus strains, which provide tropical esters and pleasant tartness. A dry hop of Cashmere and Bramling adds subtle hop character that complements the tartness. This is a highly drinkable sour that balances fruit and acidity with skill.
