Oleum is 100% plant-based; dairy products are never used. Cheeses, creams, and other traditionally dairy items come from nuts, soy, and other plant ingredients.
The kitchen operates as fully vegan, so no dairy products are kept on the premises. Every item is dairy-free by design, a fact confirmed by the brand’s menu and external listings.
Multiple items are labelled dairy-free (e.g., Barbacoa de Chivo, Pollo en Pipían Verde) while others contain dairy (e.g., Aleppo Honey Wings, Belizean Cold Cake). Menu markings are clear per item.
The menu clearly marks dishes that contain dairy, simplifying the selection of safe options. No dedicated dairy-free kitchen is described, so confirm with staff.
