Wisgy is an independently run old and rare spirits consultancy launched in 2024 by Isabel Graham-Yooll, backed by a team of independent experts.
Wisgy provides independent trusted expertise. Experience in building relationships with producers, traders, dealers, collectors and archives.
The Wisgy team offers a range of strategic support services for investors, traders, collectors, bottlers, distillers and brands. For example our complete authentication and counterfeit provenance service includes training and a one stop shop for alerting dealers about stolen bottles as well as prevention advice on avoiding fakes, fraud and theft. Our independent valuation service for collections (small or large) is ideally suited for insurance valuations as well as trade valuations and requests from private individuals.
Our network of contacts means we are able to help clients source old and rare bottles as well as find buyers for bottles and casks. Our expert team of archivists and historians are available to research archives for brands wanting to market their brands more effectively and authentically.
