Pop-Up Chef Dinners & Wine Pairing Events

One of Alder Grove’s signature offerings is a rotating series of pop-up dinners featuring guest chefs and curated wine pairings, hosted on the property under the alders. These limited-seating evenings combine the best of a chef’s table experience with the magic of dining outdoors in the Pacific Northwest — multi-course menus, thoughtful wine selections, and the kind of relaxed conversation that only happens when the table is set in a grove of trees. Past and upcoming events have featured chefs from across the region; see our Upcoming Events for what’s currently on the calendar.

Private Gatherings & Milestone Celebrations

Family reunions, milestone birthdays, anniversary parties, rehearsal dinners, vow renewals, memorial services, and graduation celebrations all find a home at Alder Grove. The property’s mix of formal and casual spaces lets you build the day exactly the way you want — a long farm-table dinner under string lights, lawn games on a Saturday afternoon, a dance floor under the stars.
