Smell. This is where you get the classic “berry on the nose” phrasing. Bosker spends the first couple of pages of her book talking about how humans rely too much on the other five senses and forget to fine-tune their sense of smell. First, think big! Think about which fruits / berries you’re smelling. This initial smell has to do with the grape itself. Then think smaller. Yeasty smell? Vanilla? Nutty? These smells come from the fermentation + aging (barrels) process. PRO TIP: To help “expand your pallet” (or the link between your sense of smell and taste buds) this article from Vogue suggests practicing putting names to smells in your everyday life. Smell the fruits in vegetables at the grocery store, try to note and verbalize what exactly you smell walking through your day-to-day. It should eventually help you pick up on the distinct smell of a distinct wine.
