According to Seedman's site, the blueberry enhancer contains: natural and artificial flavorings, purified water and propylene glycol ( USP ), ethyl alcohol, citric acid and dextrose.
I've tried a few of Seedman's flavors, but not that one yet.
The English and Commercial flavors are my favorites for mixing with other tobaccos, and I like adding a dash of the Capt. Black from time to time.
I also just got in the Virginia fire-cured, but haven't tasted it yet as I've been too swamped lately to take a break and play Betty (CC) Crocker.
On a sidenote I just checked-in my initial TPA order for the shop last night, and had to break into the English Toffee that everyone's been talking about.
At 5% I can definitely taste the Toffee notes, but I have a feeling this is one of those flavors that needs to steep to get the full experience.
Once I get some time again I'll have to play around with it in some RY4-type mixes.
