The "Aromas vs Bouquet" Class is THE BEST EVER! I use my fun aroma kit to pass around samples of fun aromas. It is very helpful for participants of the class to understand the difference in a citrus fruit, a tree fruit (coming from an orchard), and a stone fruit (a fruit that has a pit in it).
In this experience, our guests may think their a wine novice, but this is not true. We all have the ability to use our senses to recognize what it going on in the glass. My favorite is when a guest exclaims a note they are getting in the wine and I have the opportunity to say "Exactly!" I then go on to explain why they are getting those specific bouquets or aromas.
Sometimes its a primary aroma, sometimes its a bouquet coming from a process post-fermentation. Either way, guests leave learning something, having fun, and building their own wine vocabulary. A very cool experience.
