In this episode of Grown in Napa Valley, guest host Jonathan Cristaldi presents highlights from the 2025 Napa Valley Harvest Press Conference, presented by the Napa Valley Grapegrowers and Napa Valley Vintners,  joined by growers and winemakers Ashton Leutner, Mayan Koschitzky, Nate Weis, and Megan Gunderson. They unpack a cooler, steady 2025 growing season shaped by early rains, slow canopy development, minimal heat spikes, and strong fruit set. With phenolic ripeness outpacing sugar accumulation, the panel notes vibrant color, natural acidity, and balanced alcohol across the vintage.

They discuss the year’s key challenges — elevated mildew pressure and a stop-and-start harvest caused by intermittent rain — and share how tight spray intervals, sport-trap monitoring, and thoughtful canopy work helped maintain fruit quality. Market shifts also left some fruit unharvested, creating an opening for growers to redevelop vineyards, adjust crop loads, and focus on long-term soil and plant health.

The conversation turns to the Pickett Fire, which produced highly localized smoke impacts. Thanks to improved air-quality tools and advanced ETS smoke-taint testing, growers were able to assess risk with far more precision than in past fire years. Early takeaways from the panel point to a distinctive, expressive 2025 vintage — wines with strong color, refined tannins, and clear AVA character — underscoring a maturing Napa Valley rooted in adaptation, stewardship, and continuous learning.
