Review of Soho Flavor-FA:

Outstanding flavor, currently mixing at 3% plus 2% CAP Caramel, 1.5% CAP Bavarian Cream and 1.5% CAP Cinnamon Danish.

Has a small sweetener aftertaste that goes away after about a five-day steep and this is the RY4 type that should define all other RY4 blends.  Highly recommended.
