O'Brien Estate Winery

O'Brien Estate Winery is a family-owned Napa Valley winery that also offers its estate as a setting for private gatherings and organised events. Located in the Oak Knoll District, the property combines vineyard views with outdoor and indoor spaces, including a barrel cellar. Organisers can request an intimate group experience or reserve the entire estate for a private occasion.

The estate hosts groups of up to 70 guests. Its private event offering suits company retreats, client dinners, anniversary celebrations, proposals and other small gatherings. Group tastings bring guests together at a private table for estate wines, with a host guiding the experience. For larger occasions, the team can arrange tables beneath the pergola or among the vines, as well as gatherings in the cellar.

Food is not the winery's main service, but catering can be coordinated, from light bites to a seated dinner. Live music, such as a jazz trio or guitarist, can also be arranged on request. For full-estate bookings, the stated arrangement begins with six cases of estate wine rather than a separate site fee, and unopened bottles can be taken home. Smaller events are priced individually.

Event organisers can share their date, guest numbers and occasion through a special event enquiry. The owners help shape the plans personally, making the estate a distinctive option for private celebrations and company gatherings in Napa. Tastings and events are by reservation, so planners should contact the team to discuss availability and the details of their event.
