The purpose of an embodiment of the present invention is to provide a low calorie-oriented natural beverage in which a reduction in the degree of sweetness due to storage is inhibited. The beverage satisfies conditions: (A) the mass ratio of (RebD and/or RebM)/RebA is 0.52-1.58; and (B) the sum of the Brix values of RebA, and RebD and/or RebM, in terms of sucrose content, is 5-10.
