A knowledgeable and experienced kavist, helping the buyer to make a choice, focuses on his taste and takes into account many characteristics of the wine, including:
- price,
- type of wine
- country and region of origin,
- manufacturer,
- harvest year,
- the term and technology of aging, as well as the gastronomic preferences of the buyer, and much more
A cavist must be, like a sommelier, an excellent taster and psychologist.
