Descriptiontext

Spectrum Wine Auctions LLC (operating as Spectrum Wine) is a privately-held fine and rare wine and spirits auction, retail, and storage firm headquartered in Santa Ana, California. Founded in 2009, the company conducts weekly online wine and spirits auctions through its website and native iOS/Android mobile bidding applications, serving affluent collectors, estate liquidators, and repeat consignors across a global footprint spanning the United States, Europe, Asia-Pacific, and Latin America. The platform supports live online bidding with detailed lot information, complemented by direct retail e-commerce (over 3,286 SKUs at price points from under $10 to over $10,000) and complimentary confidential wine appraisals using real-time market data. Dedicated account managers handle consignment inquiries, providing inspection, cataloging, photography, and logistics services, with consignment appraisal offered at no charge and proceeds paid to consignors 30 business days after auction close.

The technology stack centers on an online auction platform supporting real-time bidding through web and mobile channels, paired with a state-of-the-art temperature- and humidity-controlled warehouse in Santa Ana that is monitored 24/7 by sensors and a professional alarm service. The firm operates satellite offices in Newport Beach, Minneapolis, and Hong Kong (with a JAS Forwarding warehouse for international lot storage), enabling cross-border consignment logistics. The company is part of a multi-vertical collectibles network that includes coins and currency entities (A-Mark Precious Metals, Stack's Bowers Galleries, Spectrum Numismatics International, Teletrade) and a financing partner (Collateral Finance Corporation), extending ecosystem reach and enabling potential collateralized lending against wine assets.

Revenue is generated through three primary streams: auction commissions (transaction-fee model on successful sales), direct retail wine and spirits sales (one-time e-commerce transactions), and storage subscriptions (recurring fees for climate-controlled custody). In November 2025, Spectrum Wine acquired Wine Exchange, combining two leading fine and rare wine platforms to create a comprehensive offering spanning sales, storage, and appraisal services. The company is founder-led with no disclosed private equity or venture capital backing, and operates with 11-50 employees across its offices.
