Carbon Beefsteak represents a distinguished heirloom tomato cultivar prized for its striking appearance, robust flavor profile, and exceptional field performance among large black tomato varieties. This indeterminate plant produces blocky, substantial fruits weighing 10–14 ounces, characterized by distinctive dark olive shoulders that transition to deep brick-red coloration at the base—a visual signature that commands attention at farmers' markets and on the dinner table. The variety demonstrates superior resistance to common physiological disorders affecting large-fruited tomatoes, including fruit cracking and cat-facing, resulting in consistently marketable yields with minimal culling. The complex flavor delivers the concentrated sweetness and umami depth characteristic of premium heirloom black tomatoes, with balanced acidity that enhances both fresh consumption and cooked applications. Organically grown and non-GMO, the 25-seed packet contains open-pollinated genetics enabling seed-saving for future seasons, supporting long-term garden sustainability and cost efficiency. Maturation occurs approximately 75 days from transplant, with indeterminate growth habit ensuring continuous production throughout the growing season in warm climates. Carbon thrives in USDA zones 3–11 with full sun exposure, consistent moisture management, and well-amended soil rich in organic matter and balanced nutrients. The well-proportioned plant architecture facilitates pruning and air circulation, reducing disease pressure while maximizing fruit quality. Ideal for home gardeners, small-scale growers, and competitive exhibitors seeking an heirloom beefsteak combining visual distinction with reliable productivity and exceptional culinary merit.
