USKO Original is an alcohol-free vodka alternative developed by brothers Roddy and Kerr Nicoll of Spirits of Virtue. The base liquid uses Deeside spring water sourced from the Cairngorm mountains near Balmoral Castle in Scotland, a point the brand positions as central to the product's character. USKO is designed to be mixed at a 1:3 ratio with mixers rather than served neat, making it a functional substitute in long drinks and cocktails. It sits alongside a citrus expression in the brand's range.
