Purple Yam: Definition & Origin
Purple yam is the common English name for ube (pronounced oo-beh), scientifically known as Dioscorea alata. It's a vine-grown tuber native to Southeast Asia that has been cultivated in the Philippines for centuries. In Filipino culture, ube is a beloved ingredient used in iconic dishes like ube halaya (purple yam jam), halo-halo (shaved ice dessert), and pandesal (bread rolls).
The finest purple yam comes from the Pangasinan province in the Philippines, where volcanic soil and tropical climate produce roots with the deepest purple color and richest flavor profile. This is where UBE NOLIA® sources its ube, directly from farmers in Dagupan and Urdaneta.

What Does Purple Yam Taste Like?
Purple yam has a unique flavor that surprises most first-timers. It's mildly sweet with aromatic notes of vanilla, hazelnut, and sometimes almond or coconut. Unlike regular yams or potatoes, ube is not starchy or earthy. It's smooth, delicate, and genuinely aromatic.
This distinctive profile is why ube works so well in both lattes and pastry. It adds flavor depth and natural color without overpowering other ingredients. When processed into powder with low-temperature drying, these aromas are preserved at their peak.
