I ordered some unflavored base from Mt Baker and a few flavors so I could mix them myself. After putting in bottles with 20% flavor the Lemonade and Cherry flavors have a round "oil" looking ball in the bottom of the bottle. I put them in a heated ultrasonic cleaner for two hours and have shaken them daily for over two weeks now. The oil looking substance always separates from the rest of the juice and goes to the bottom. Anyone experienced this? I called their support and the guy told me that it was a common occurrence and not to worry about it. Just seems weird to me that it won't mix.
