Black Spanish is a specific variety of grape widely planted in the Southwestern United States, Mexico, and South America. When it comes to antonyms for this term, we can consider several options, depending on the context. If we take Black Spanish as a color reference, then the opposite would be white or light-colored. However, if we assume it as a grape variety, then we could use other grape names as antonyms. For example, white grape varieties like Chardonnay, Pinot Grigio, or Sauvignon Blanc can serve as antonyms. Alternatively, we could use black grape synonyms such as Cabernet Sauvignon, Merlot, or Pinot Noir.
