This medium flavor-intensity dish requires a medium intensity wine. If the wine has too much or too little intensity, either the flavor of the food or the flavor of the wine will be lost and you will miss the opportunity to enjoy the interplay of the two flavors.
The right wine for this acidic dish needs to be low in acidity. If the acidity is too high, the wine will clash with the food resulting in an unpleasant sour or tart taste.
For this acidic dish, the right wine needs to have low tannin. If the tannin is too high, the wine will clash with the acidity in the food, creating a dominant bitter or astringent taste rather than a balanced taste of the wine and food flavors.
To complement the bright, focused fruit flavor of the tomato, the right wine needs to have a bright and focused fruit flavor as well.
