Episode 154: Soil, Sheep, and Superior Grapes with Ivo Jeramaz

Ivo Jeramaz, a mechanical engineer turned vintner, immigrated from former Yugoslavia (now Croatia) to Napa Valley, where he rediscovered his ancestral connection to farming. Initially resentful of agriculture due to its demands in his youth, Ivo’s perspective shifted dramatically within weeks of arriving in Napa, where he embraced grape growing and winemaking as a fulfilling life’s work, now leading Grgich Hills Winery with a commitment to regenerative practices.

Raised in a family that produced much of their own food and clothing, Ivo brings a deep-rooted appreciation for self-sufficiency and nature to his work at Grgich Hills. With six children and a passion for biodiversity, he is dedicated to promoting regenerative farming, aiming to convert Napa Valley’s vineyards to sustainable practices while producing high-quality wines that reflect the health of the land.

In this episode, John and Ivo discuss:

• Ivo’s quick adoption of regenerative practices and how it impacted soil organic matter

• How diverse cover crops and sheep grazing enhance vineyard resilience

• The impact of regenerative farming on grape quality, including thicker cuticles

• Challenges of red blotch virus and how regenerative practices help vines coexist with it

• Ivo’s vision for a regenerative future in Napa Valley
