We are the ‘treasure hunters’ of the wine world, proudly offering you hard-to-find and limited-production wines not often found on retail shelves. Our team scours the globe for some of the most distinctive wines—from shipwrecked 1907 Champagne taken from the bottom of the Baltic Sea—to exclusive Italian wines known only by their small-town neighbors delivered with pristine provenance. We update our website daily with new treasures. Need help finding a unique wine? Contact us through our chatbot (live wine advisor available M-F, 8AM-5PM PST) or email


Wine is our passion! We enjoy procuring the best wines that surprise and delight our customers. Our experienced team of wine advisors, wine buyers, sommeliers, former restaurant owners and wine directors know how to find the best wines domestically and internationally. We’re located in the heart of California’s wine country and have deep relationships with distinguished winemakers. We have access to a selection of exclusive, limited-production wines that are unlikely to reach mainstream wine-store shelves.

Glenn siegel

Founder and President

Glenn Siegel launched Wine Spectrum in 1990 with the goal of making remarkable wines available to wine enthusiasts everywhere. In his international travels, he discovered that truly great wine is often difficult to find, so he began developing relationships with respected winemakers along the way.

His unique person-to-person direct sales philosophy helped him develop rewarding, long-lasting relationships with wine lovers everywhere. His devotion to the wine business also earned him respect among winemakers, giving him access to highly-allocated wines.

As a wine expert, he is often sought out for his opinion and has been quoted in “The Wine Spectator,” several newspapers and business magazines, and even made a special appearance on the “Today Show.” Even in this high-tech, fast-paced world, Glenn believes busy people still prefer a personal touch. By maintaining a well-trained and experienced staff of wine advisors, Wine Spectrum provides new and returning customers alike good, old fashioned personalized care along with some great wine!


Wine Spectrum is managed by a team of professionals dedicated to steering the organization into its next 30 years of success.
