28 Days: This is very good. 7 days is really all you need, but it does get more "deep" around 2 weeks. Holding strong at 28 days with only a slight fade. I'm not picking up any fizz, but it does taste like Black Cherry Soda. Maybe a good-quality hard candy/lollipop if you didn't know it was a soda base.
This Cherry extract is very nice. No medicinal or chemical notes. Just a nice, deep Black Cherry. Available at diyvaporsupply.
