Chemically, both cane and beet sugar are sucrose, making them nearly identical in sweetness and structure.

Cane sugar: extracted from sugarcane (a tropical grass).

Beet sugar: extracted from the sugar beet (a root vegetable).

While they are interchangeable in almost all recipes, beet sugar can carry a subtle "earthy" aroma, while cane sugar is perceived as having a cleaner or "fruity" aftertaste.
