Sept 9th, Sept 17th, and Oct 8th only. From 9:45 a.m. to 11:30 a.m. Walk our beautiful upper vineyard with views of the Dry Creek Valley just before harvest with winemaker Katarina. During this unique experience in a small group, we will pick cabernet sauvignon grape samples and field test sugar, pH, and of course taste. She will share how we decide when to harvest and other winemaking topics. Each walk includes and will end with a guided wine tasting flight on our vine-side patio. (Group size limited to 10. Wear comfortable closed toe shoes with good soles as this is uneven hillside terrain.) $60, $30 for Compass Club Members – please call Tasting Room to reserve: 707-433-2066.
