We invite our wine club members to join us for our annual sailing event! We have chartered the 80-foot classic schooner Freda B for an afternoon on the water. Given our vineyard’s namesake, we feel the San Francisco Bay is a setting well-befitting for tasting the wines of Poseidon Vineyard. We'll depart from Sausalito and embark on a 3-hour cruise around the Bay, enjoying incredible views, delicious seafood chowder and of course, Poseidon Vineyard wine. Space is extremely limited and tickets are sold on a first come, first served basis. $50/person for our wine club members (up to 2 tickets); $90/person additional tickets. RSVP IS REQUIRED.
