Rainier Cherries have a delicately floral, sweet flavor with notes of peaches and a caramel-like finish on the palate. Rainier cherries are a good source of potassium to balance fluid levels within the body and fiber to regulate the digestive tract. The fruits also contain vitamins A and C to reduce inflammation, strengthen the immune system, and boost collagen production within the skin, and provide lower amounts of copper and manganese.
