Has anyone taste-tested some of the gazillion sour cherry juices and juice concentrates that are for sale? I've tried Cheribundi, which tastes great, very $$$, and Smart Juice, much less expensive, which tastes okay, not as excellent. I mixed them. I'd like to find sour cherry juice (usually called tart cherry juice or Montmorency cherry juice) that tastes good w/o added sugar. I tried Lakewood's (??) and that was not good--mixed juices, and didn't taste like sour cherry. All these juices are quite expensive, but there are big health claims (e.g., Dr. Oz) for sour cherry juice, for arthritis pain, antioxidants, and even melatonin, for sleep aid. Can anyone contribute information on what they've tried and liked? Thanks.
