About the Index

The Madeira Index ("RWI-MW8") is designed to provide a transparent benchmark for tracking the price performance of vintage and solera madeira wines from established producers. Using repeat sales regression methodology on quarterly auction transaction data, the index reflects real-world secondary market valuations across eight leading producers (Blandy's, d'Oliveiras, Barbeito, Cossart Gordon, Justino's, Leacock, Henriques & Henriques, and H.M. Borges).
