Diamond Bar Friends Of The Library Wine Soirée And Benefit Auctions

Diamond Bar Friends Of The Library Wine Soirée And Benefit Auctions is an annual grand tasting fundraiser held each spring in Diamond Bar, California — now in at least its 32nd year, the event typically draws hundreds of guests and supports the Diamond Bar Library and local literacy programs. The 2026 edition is scheduled for Sunday, June 7, 2026. All proceeds benefit the Diamond Bar Friends of the Library, a 501(c)(3) nonprofit established in 1977 and incorporated in 1996.

The Diamond Bar Friends Of The Library Wine Soirée And Benefit Auctions gives attendees the opportunity to sample wines from around the world alongside food provided by local restaurants. The evening also features a live auction, a silent auction, a book auction, raffles with dozens of prizes, and live music — making it a multi-format fundraising event rather than a straightforward wine tasting. The suggested dress code is "California casual," though the organizers note that guests in everything from a coat and tie to jeans and a Hawaiian shirt will feel at home. Comfortable shoes are recommended.

Tickets can be purchased online in advance — online purchases are held at Will Call — or at the door, though advance purchase is encouraged. A limited quantity of tickets is also available at the Friends' bookstore inside the Diamond Bar Library. All attendees must be 21 or older, and proof of age may be requested at the reception desk. The Diamond Bar Library is one of 88 branches in the Los Angeles County Library System and is consistently rated among the top 3 branches for patron visits and materials checked out.

Revenue raised at the Diamond Bar Friends Of The Library Wine Soirée And Benefit Auctions underwrites Summer Reading Programs for children, teens, and adults, funds new books and media for the library's collections, and supports capital improvement projects. Surplus funds are directed to the library's Endowment Fund, created to provide a stable, long-term funding source for the Diamond Bar Library.
