Sustaina Wines is the associated agency specializing in sustainable wines and spirits. Its offerings include an exclusive portfolio of international producers as well as a broad network for the strategic sourcing of your required products and private labels.
Peter Douglas works at the intersection of sensory excellence and strategic procurement. His career in the wine industry began in 2009 in the fine dining sector, where stints at renowned establishments shaped his understanding of quality.
The logical next step into the industry led him to spend four years in category management at a major e-commerce player. There, he managed the wine markets in France, Spain, Italy, Eastern Europe, and the U.S., and was responsible for purchasing spirits and beverages in the private-label segment.
Today, he applies this expertise on an international scale. With his WSET Level 4 certification, Douglas combines global sourcing with strategic consulting. Through his agency, Sustaina Wines, he serves as an expert liaison between international producers and decision-makers in the retail sector.
We have been working with Sustaina Wines since 2023. As a ship supplier, we require an enormous range of international wines—from champagne to wines from Eastern Europe. The sourcing and the entire process run absolutely smoothly and like clockwork.

Peter verfügt über umfassende Kenntnisse der europäischen Weinbranche und ist ein hervorragender Partner für die Weiterbildung in der Branche! Er hielt nicht nur auf der diesjährigen Bar Convent Berlin einen aufschlussreichen Vortrag zum Thema Eigenmarken im Weingeschäft, sondern konnte uns dank seines starken Netzwerks in der europäischen Weinbranche auch andere hervorragende Referenten vorstellen. Wir hatten großes Glück, dass Peter mit uns zusammengearbeitet und sein Fachwissen mit uns geteilt hat!
