Thunderbird is a low-quality, inexpensive wine made by the Ernest and Julio Gallo Winery. The liquor is light yellow, but it turns the lips and mouth black.
The Ernest and Julio Gallo Winery started producing Thunderbird wine after Prohibition ended, targeting a young market. Fermented Reviews reports a hint of citrus and some sweetness in the flavor. The wine also features a high alcohol content: 17.5 percent by volume. The extra alcohol adds burn to the flavor. Marketed as "The American Classic," Thunderbird has a reputation as being a cheap way to get drunk; 750 mL generally costs less than $3.
