French Vanilla Deluxe Flavor This is a stronger, richer French Vanilla. It may be too strong for some, but we still have our original French Vanilla! *** Note: This flavor contains 'custard' ingredients: Acetoin & Acetylpropionyl. The following link explains the frequent questions & concerns involving custard notes. http://shop.perfumersapprentice.com/flavorsworkshop/custard.html? Our original French Vanilla does not contain these custard ingredients.
