Tunan on the menu? Try pairing with Merlot, Pinot Noir, and rosé Wine. Though fish is often paired with white wine, 'meatier' fish like tuna can absolutely go with red wine. A Rosé will also pair nicely, particularly if your tunan is prepared with ingredients better suited to a white wine. The Flora Springs Napa Valley Merlot with a 4.2 out of 5 star rating seems like a good match. It costs about 18 dollars per bottle.
