Hal likes to say that he was born a tree hugger, even though he was actually born in southeast Los Angeles, a land of very few trees. After two careers in New York and attending medical school for a PhD in brain science, Hal returned to his native California to do something good for the earth. In 2010 & 2012, he bought two adjoining ranches in Geyserville, the heart of Sonoma’s Alexander Valley. By 2016 he had restored its creeks, replanted the vineyards, repaired the existing roads and started his first vintage. Working first with Jesse Katz (now of Aperture) from 2014 to 2018 and now with Kate Nowell-Smith, starting in 2019, he has set about to make the highest quality Bordeaux varietal wines, that are most fitting to the Alexander Valley, in the most earth friendly way. High-end viticulture is inherently an intense farming activity that can be very hard on the land. Through careful, yet unrelenting practices to support his motto “great wines come from a healthy planet”, Hal has pushed the envelope on sustainability from organic, to fish and bee friendly, all the way to climate friendly. Today, the team at Sei Querce is working to be among the first to produce certified carbon neutral wines in the United States. And with the daily farming and winemaking in the hands of his team, Hal focuses his energies leading Global Bamboo Technologies/BamCore as CEO, where he hopes to have an even broader impact doing good for the earth.
