Dan Petroski is the winemaker of Larkmead Vineyards and the founder & winemaker of Massican. Recently, Dan spoke on a panel regarding climate change and sustainability in relation to the global wine industry. Leaving me with more questions, we sat down to chat about the effects of climate change on Napa Valley specifically, with a focus on the benchmarking and data gathering that Larkmead has been doing to assess things like growing degree days in detail, and how Napa Valley is evolving into Zone 5 climatic conditions. We also discuss the affects of alternative packing and how that crosses over in the marketing & customer perception. Then we dig into how Dan is preparing for the potential major effects of climate change with a 21 year plan for testing other grape varietals that might possibly be more viable in the long-term. For those who do not know Dan, I encourage you to go back and list to my original interview with him where we discussed being the winemaker of Larkmead Vineyards in Calistoga, California and the founder & winemaker of Massican, Dan’s all white wine label making beautiful expressions of Italian based white wines like a Pinot Grigio & Greco blend called Gemina.
