Four Sisters Ranch Vineyards & Winery hosts weddings, company events and private celebrations for up to 300 guests. The family-owned estate sits in San Miguel, in the Paso Robles wine region of California, and combines a large indoor and outdoor event space with gardens, lawns and a barrel room on a working vineyard.
Seminars and company events
The ranch sells corporate events alongside private parties: staff meetings, team training and retreats, team-building days, company holiday parties, summer picnics and employee appreciation events. The lawns are set up for outdoor games, including bocce, horseshoes, lawn bowling and ring toss, and there are fire pits and Adirondack chairs for informal breaks between sessions. A raised outdoor stage suits speeches, award presentations or a live band. The site does not list audiovisual equipment, so technical needs should be discussed with the team at the planning stage.
Weddings and receptions
Weddings are a core part of the offer. Ceremonies take place on the hilltop above the vines or under a decorated pavilion, and receptions move to the main event space and the courtyard garden, lit with bistro lights after sunset. The Barrel Room can host a rehearsal dinner the evening before. The wedding team prepares custom packages, and private tours of the property can be arranged for couples before they decide.
Rooms and capacities
The main event space covers 7,000 square feet, combining indoor and outdoor areas with an enclosed lawn, and holds up to 300 guests. The courtyard and garden add 4,000 square feet with raised seating areas facing the vineyard. The Barrel Room is the smaller option, used for private tastings, dinners and rehearsal dinners. Tables and chairs for up to 300 guests are supplied, along with indoor and outdoor event lighting. Security staff are provided according to guest count.
Accommodation
A fully equipped bridal suite with its own bathroom is available on event days. The ranch does not list guest bedrooms, so groups stay in hotels around Paso Robles.
Catering
An outdoor barbecue and tasting bar is equipped with a wood-burning pizza oven, a gas grill and beer taps. The winery pours its own wines, including Chardonnay, Zinfandel, Syrah, Cabernet Sauvignon, Tempranillo and two sparkling wines made by the traditional method. The site does not state its catering policy, so the menu and the caterer are agreed with the events team.
History and setting
The family established the ranch in 1989 and grows eight grape varieties. The tasting room looks over the vines and has a wood-burning fireplace and three patios. The property describes itself as family and pet friendly, which makes it an easy setting for company picnics that include families.
Getting there
The ranch is at 2995 Pleasant Road, San Miguel, a few minutes by car from downtown Paso Robles. Guests park on site, and valet parking can be added. The tasting room opens Wednesday to Sunday, with Monday and Tuesday by appointment, which helps when planning a site visit.
