Ube and taro are often grouped together because they can both appear in purple drinks and desserts, but they are different ingredients.
In cafes, ube is often used when the goal is a bold purple latte or a sweeter signature drink. Taro is more common in milk tea and powder-based mixes.
If you want a menu item with stronger visual impact and a softer, more indulgent taste, ube is usually the better choice.
