A very nice baked cinnamon-bun flavour.
Personally tested at 70/30 PG/VG at 10% and at 20% flavour by total volume .
At 10% the flavour strength is ok, at 20% the flavour is very full and rich and could even be dropped back to about 15% for my tastes.
Taste profile: Mild cinnamon flavour as you would expect from the real thing
with a sweet icing and bun tone dominating. Good as a standalone.
YMMV (your mileage may vary)
