The wine industry in Monterey County has undergone a remarkable transformation — one that reflects the interplay of climate, vineyard strategy, and scientific research. With nearly four decades of experience, viticulture advisor and researcher Larry Bettiga shares how growers have refined their practices to succeed in this unique coastal region.
Climate and Variety: Match Matters
Monterey’s cool, fog-influenced coastal climate presents both opportunity and constraint. Early plantings often struggled because the variety-site match wasn’t optimal. Over time, growers began leaning into better temperature modeling, clone selection, and site characterization. These practices helped ensure that vines selected could thrive under the region’s wind-swept, marine-moderated conditions — so the rootstock and variety truly align with what the land offers.
Rootstocks, Establishment, and the Vine Life Cycle
One of the major shifts has been in how vineyards are established, from selecting rootstocks to choosing grafted vines over own-rooted material. Research has shown that the choice between dormant vines, green-potted vines, or tall-format grafted vines has lasting implications for vine health, disease resistance, and yield stability. In Monterey, growers learned that building the vineyard with intention — rather than defaulting to traditional methods — leads to stronger performance.
Canopy, Disease, and Long-Term Performance
Disease pressure, canopy management, and trellis design are all intertwined. For example, phylloxera, powdery mildew, and botrytis challenged early plantings and forced experimentation with trellising and canopy systems. Growers learned how to optimize airflow, sunlight penetration, and spray coverage. Larry’s long view of research in this region demonstrates how embracing applied science can lead to measurable benefits in vineyard longevity, fruit quality, and operational resilience.
By weaving together history, site-specific science, and actionable grower insights, the story of Monterey County becomes more than a regional origin — it becomes a blueprint for vineyard managers seeking to make smart, enduring choices.
