Paso Robles, Calif., – Robert Hall Winery, a leader in the Paso Robles American Viticultural Area (AVA) and a Regenerative Organic Certified® winery, is celebrating the one-year anniversary of the Regenerative Viticulture Foundation (RVF)’s One Block Challenge. Please enjoy the below reels about this important milestone:
The initiative, launched by RVF in partnership with Robert Hall in 2025, invites grape growers to dedicate one vineyard block for at least one year to regenerative practices, enabling growers to test regenerative practices to learn farming practices and outcomes. Robert Hall Winery, owned by O’Neill Vintners & Distillers, is part of a growing group of Paso Robles AVA leaders-including Tablas Creek, MAHA Estate, Booker, and Halter Ranch-that are driving the adoption of sustainable, climate-resilient farming practices in the region. At the forefront of this effort, Robert Hall Winery has conducted the region’s only living regenerative organic viticulture case study, showing a side-by-side comparison of regenerative organic and conventionally farmed vineyards to rigorously evaluate impacts on soil health, carbon sequestration, and fruit and wine quality.
The study spans 40 acres of Robert Hall estate vineyards and tracks a comprehensive suite of vineyard and winemaking metrics, including soil carbon, microbiology, biodiversity, yield, grape chemistry, phenolics, and sensory outcomes.
The One Block Challenge provides a crucial platform for collaboration and knowledge-sharing among growers, reinforcing Paso Robles’ reputation as a global epicenter for regenerative viticulture. The initiative is proving instrumental in demonstrating the practical benefits of regenerative viticulture and for accelerating its adoption at scale.
To highlight the influence of Regenerative Organic Certified® farming and Robert Hall’s pioneering role, ROC Tasting Kits have been created and are available to both media and trade. The kit includes two types of samples: “conventionally farmed” wines made from sustainably farmed grapes and a counterpart wine made from Regenerative Organic Certified® grapes, allowing for a direct comparison tasting experience across three vintages. Please respond to this media alert if you would like to receive a ROC Tasting Kit.
