Smoothie Sours take the fruited sour base and push it toward near-purée intensity. Defined by heavy fruit loading, thick viscosity, and a soft, low-acid structure, these beers drink more like blended fruit beverages than traditional tart ales. Carbonation is often subdued to support the dense texture, and the focus is squarely on raw fruit expression, colour, and mouthfeel rather than pastry-like sweetness or dessert character. Smoothie Sours are built around volume, body, and bold fruit presence.
