Okay kiddo, you know how when you smell something, it gives you an idea of what it might taste like? Well, just like with food, wine has a smell that can give us an idea of what it might taste like.
When you take a good sniff of wine, you might smell things like fruit, flowers, spices, or even things like leather or earthy smells. These smells are called the wine's aroma, and they come from different things in the wine.
The fruit smells come from the grapes that the wine is made from, and different types of grapes can give off different smells. The flowers and spices might come from the barrels that the wine was stored in, or from the yeast that was used to ferment the wine. And those earthy smells might come from the soil where the grapes were grown.
So basically, the aroma of wine can give us hints about what the wine might taste like, and where it came from. It's like smelling a secret code that tells us all about the wine before we even take a sip!
