World’s Darkest Tomato-- the darkest tomato we know of! A dark, meaty, very rich-fleshed tomato with extreme anthocyanin expression (same antioxidant in blueberries and blackberries). So dark that some tomatoes turn solid blue-black on the skin. Deep red flesh is among the best tasting of all tomatoes. Rich, smooth and savory with earthy tones. Hangs well on the vine and stores very well, and the flavor improves with room-temperature storage. Our own Dave Kaiser tasted it at the 2015 National Heirloom Exposition and proclaimed it as the BEST tomato he had ever eaten.
