Annual Wine Club Sail on the Bay

1:30pm to 5:00pm
Saturday, July 28, 2018

Venue: Sausalito Yacht Harbor, Sausalito, CA


Given our vineyard’s namesake, we feel the Bay is a setting well-befitting for tasting and celebrating the wines of Poseidon Vineyard, so we've chartered the 80-foot classic schooner Freda B for our annual wine club sailing event. We'll depart from Sausalito and embark on a 3-hour cruise around the Bay, enjoying incredible views, local cheese and charcuterie, and of course, plenty of Poseidon Vineyard wine. Tickets are $70/member, up to 2 tickets; any additional are $110/person. Space is extremely limited; this event is for club members only. RSVP is required.
