To you, what makes a fine wine?
Red or White?
What are a few factors that contribute the most to the characteristics of a wine such as the grapes, soil the grapes are grown, climate of region, weather of the year grapes were grown?
What is your “desert island” bottle of wine?
Interesting question. Whites and Reds both are made into fine wines. All of the characteristics you mention are a part of what make up the taste, aroma, and mouth feel of wines. This is terroir. As to the bottle on a desert island. Since it will likely be fish or seafood, a Vincent Dauvissat 2017 Chablis.
