I'm having a problem mixing any flavors that have cinnamon in them. Specifically capella's cinnamon danish swirl and flavor west's churro flavors. If I mix them to where they taste great at the time of mixing, after a week or so they are very week. FW churro for example; When I received it, I mixed up a sample batch of just that flavor at 10%. Next day it tasted great. A week later I could barely taste any cinnamon at all and the juice was just bland. I remixed at 15%. A little strong on the cinnamon a day after mix. A week later. Bland. Made another batch at a whopping 20%. Didn't taste it the next day, but a week later it was barely as strong as the 10% batch on the day of mixing. CDS is the same way. What is the trick to getting the cinnamon flavor to be present without having to use an astronomical amount of flavoring?
